Notes to Consolidated Financial Statements

(Unaudited)

NOTE A – BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES

We are a geographically diversified oil and gas services company focused on completion fluids and services, production testing, wellhead compression, and selected offshore services including well plugging and abandonment, decommissioning, and diving. We were incorporated in Delaware in 1981. We are composed of five reporting segments organized into three divisions – Fluids, Offshore, and Production Enhancement. Included in our Offshore Division is our Maritech segment, an oil and gas exploration and production business that sold approximately 95% of its proved oil and gas reserves in the first eight months of 2011, and whose continuing operations consist primarily of the ongoing well plugging, abandonment, and decommissioning of its remaining offshore production platforms. Unless the context requires otherwise, when we refer to “we,” “us,” and “our,” we are describing TETRA Technologies, Inc. and its consolidated subsidiaries on a consolidated basis.

The consolidated financial statements include the accounts of our wholly owned subsidiaries. Investments in unconsolidated joint ventures in which we participate are accounted for using the equity method. Our interests in oil and gas properties are proportionately consolidated. All significant intercompany accounts and transactions have been eliminated in consolidation.

The accompanying unaudited consolidated financial statements have been prepared in accordance with Rule 10-01 of Regulation S-X for interim financial statements required to be filed with the Securities and Exchange Commission (SEC) and do not include all information and footnotes required by generally accepted accounting principles for complete financial statements. However, the information furnished reflects all normal recurring adjustments that are, in the opinion of management, necessary to provide a fair statement of the results for the interim periods. The accompanying unaudited consolidated financial statements should be read in conjunction with the audited financial statements for the year ended December 31, 2010.

Certain previously reported financial information has been reclassified to conform to the current year period’s presentation. The impact of such reclassifications was not significant to the prior year period’s overall presentation.

Cash Equivalents

We consider all highly liquid cash investments with a maturity of three months or less when purchased to be cash equivalents.

Restricted Cash

Restricted cash is classified as a current asset when it is expected to be repaid or settled in the next twelve month period. Restricted cash reported on our balance sheet as of September 30, 2011, consists primarily of escrowed cash associated with our July 2011 purchase of a new heavy lift derrick barge. The escrowed cash will be included in restricted cash and released to the sellers in accordance with the terms of the escrow agreement.

Inventories

Inventories are stated at the lower of cost or market value and consist primarily of finished goods. Cost is determined using the weighted average method. Significant components of inventories as of September 30, 2011, and December 31, 2010, are as follows:

	September 30, 2011		December 31, 2010
	(In Thousands)
Finished goods	$	70,433	$	75,874
Raw materials		5,391		5,103
Parts and supplies		21,234		22,457
Work in progress		445		871
Inventories	$	97,503	$	104,305

5

Finished goods inventories include newly manufactured clear brine fluids and recycled brines that are repurchased from certain of our customers. Recycled brines are recorded at cost, using the weighted average method.

Net Income per Share

The following is a reconciliation of the weighted average number of common shares outstanding with the number of shares used in the computations of net income per common and common equivalent share:

	Three Months Ended				Nine Months Ended
	September 30,				September 30,
	2011		2010		2011		2010
Number of weighted average common
shares outstanding		76,717,063		75,538,455		76,517,144		75,469,030
Assumed exercise of stock options		1,622,958		1,082,591		1,587,783		1,283,383
Average diluted shares outstanding		78,340,021		76,621,046		78,104,927		76,752,413

In applying the treasury stock method to determine the dilutive effect of the stock options outstanding during the first nine months of 2011, we used the average market price of our common stock of $12.28. For the three months ended September 30, 2011 and 2010, the calculations of the average diluted shares outstanding exclude the impact of 2,054,303 and 2,668,312 outstanding stock options, respectively, that have exercise prices in excess of the average market price, as the inclusion of these shares would have been antidilutive. For the nine months ended September 30, 2011 and 2010, the calculations of the average diluted shares outstanding exclude the impact of 1,874,492 and 2,311,805 outstanding stock options, respectively, that have exercise prices in excess of the average market price, as the inclusion of these shares would have been antidilutive.

Environmental Liabilities

Environmental expenditures that result in additions to property and equipment are capitalized, while other environmental expenditures are expensed. Environmental remediation liabilities are recorded on an undiscounted basis when environmental assessments or cleanups are probable and the costs can be reasonably estimated. Estimates of future environmental remediation expenditures often consist of a range of possible expenditure amounts, a portion of which may be in excess of amounts of liabilities recorded. In such an instance, we disclose the full range of amounts reasonably possible of being incurred. Any changes or developments in environmental remediation efforts are accounted for and disclosed each quarter as they occur. Any recoveries of environmental remediation costs from other parties are recorded as assets when their receipt is deemed probable.

Complexities involving environmental remediation efforts can cause the estimates of the associated liability to be imprecise. Factors that cause uncertainties regarding the estimation of future expenditures include, but are not limited to, the effectiveness of the anticipated work plans in achieving targeted results and changes in the desired remediation methods and outcomes as prescribed by regulatory agencies. Uncertainties associated with environmental remediation contingencies are pervasive and often result in wide ranges of reasonably possible outcomes. Estimates developed in the early stages of remediation can vary significantly. Normally, a finite estimate of cost does not become fixed and determinable at a specific point in time. Rather, the costs associated with environmental remediation become estimable as the work is performed and the range of ultimate cost becomes more defined. It is possible that cash flows and results of operations could be materially affected by the impact of the ultimate resolution of these contingencies.

Fair Value Measurements

Fair value is defined as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date” within an entity’s principal market, if any. The principal market is the market in which the reporting entity would sell the asset or transfer the liability with the greatest volume and level of activity, regardless of whether it is the market in which the entity will ultimately transact for a particular asset or liability or if a different market is potentially

6

more advantageous. Accordingly, this exit price concept may result in a fair value that may differ from the transaction price or market price of the asset or liability.

Under generally accepted accounting principles, the fair value hierarchy prioritizes inputs to valuation techniques used to measure fair value. Fair value measurements should maximize the use of observable inputs and minimize the use of unobservable inputs, where possible. Observable inputs are developed based on market data obtained from sources independent of the reporting entity. Unobservable inputs may be needed to measure fair value in situations where there is little or no market activity for the asset or liability at the measurement date and are developed based on the best information available in the circumstances, which may include the reporting entity’s own judgments about the assumptions market participants would utilize in pricing the asset or liability.

We utilize fair value measurements to account for certain items and account balances within our consolidated financial statements. Fair value measurements are utilized in the allocation of purchase consideration in acquisition transactions to the assets and liabilities acquired, including intangible assets and goodwill. In addition, we utilize fair value measurements in the initial recording of our decommissioning and other asset retirement obligations. Fair value measurements may also be utilized on a nonrecurring basis, such as for the impairment of long-lived assets, including goodwill. The fair value of our financial instruments, which may include cash, temporary investments, accounts receivable, short-term borrowings, and long-term debt pursuant to our bank credit agreement, approximate their carrying amounts. The fair value of our long-term Senior Notes at September 30, 2011, was approximately $334.8 million compared to a carrying amount of approximately $305.0 million, as current rates are more favorable than the Senior Note interest rates. We calculate the fair value of our Senior Notes internally, using current market conditions and average cost of debt. We have not calculated or disclosed recurring fair value measurements of non-financial assets and non-financial liabilities.

During the second quarter of 2011, in connection with the sale of substantially all of our Maritech oil and gas producing properties, we liquidated our derivative contracts and paid $14.2 million to the counterparty. For further discussion see Note F – Hedge Contracts.

During the second quarter of 2011, Maritech recorded impairment charges of approximately $9.2 million associated with its remaining oil and gas properties. During the first nine months of 2011, Maritech sold approximately 95% of its oil and gas reserves as of December 31, 2010, and it is seeking to sell its remaining properties at current market values. Accordingly, all of Maritech’s remaining oil and gas properties as of September 30, 2011, have been reclassified to oil and gas properties held for sale and their net book values have been adjusted to fair value less cost to sell. Fair values are estimated based on current market prices being received for these properties’ expected future production cash flows, using forward oil and natural gas pricing data from published sources. Because such published forward pricing data was applied to estimated oil and gas reserve volumes based on our internally prepared reserve estimates, such fair value calculation is based on significant unobservable inputs (Level 3) in accordance with the fair value hierarchy.

A summary of the nonrecurring fair value measurements discussed above as of September 30, 2011 and 2010, using the fair value hierarchy is as follows:

New Accounting Pronouncements

In September 2011, the Financial Accounting Standards Board (FASB) published Accounting Standards Update (ASU) 2011-08, “Intangibles – Goodwill and Other (Topic 350), Testing Goodwill for Impairment” (ASU 2011-08), which simplifies how entities test goodwill for impairment. The amendments in ASU 2011-08 permit an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test described in Topic 350. The ASU is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. Early adoption is permitted. The adoption of ASU 2011-08 is not expected to have a significant impact on our financial statements.

In June 2011, the FASB published ASU 2011-05, “Comprehensive Income (Topic 220), Presentation of Comprehensive Income” (ASU 2011-05), which has the objective of improving the comparability, consistency, and transparency of financial reporting and increasing the prominence of items reported in other comprehensive income. As part of ASU 2011-05, the FASB decided to eliminate the option to present components of other comprehensive income as part of the statement of changes in stockholders’ equity, among other amendments in this ASU. The amendments require that all non-owner changes in stockholders’ equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The amendments in this ASU are to be effective for fiscal years, and interim periods within those years, beginning after December 15, 2011, and the amendments are to be applied retrospectively. In October 2011, the FASB announced that it will consider deferring certain aspects of ASU 2011-05. The adoption of the accounting and disclosure requirements of this ASU is not expected to have a significant impact on our financial statements.

In May 2011, the FASB published ASU 2011-04, “Fair Value Measurement (Topic 820) – Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs,” whereby the FASB and the International Accounting Standards Board (IASB) aligned their definitions of fair value such that their fair value measurement and disclosure requirements are the same (except for minor differences in wording and style). The Boards concluded that the amendments in this ASU will improve the comparability of fair value measurements presented and disclosed in financial statements prepared in accordance with U.S. GAAP and IFRS. The amendments in this ASU are effective during interim and annual periods beginning after December 15, 2011, and are to be applied prospectively. The adoption of the accounting and disclosure requirements of this ASU will not have a significant impact on our financial statements.

NOTE B – ACQUISITIONS AND DISPOSITIONS

In March 2011, we acquired a project management and engineering consulting services business that provides liability and risk assessment services for domestic and international offshore well abandonment and decommissioning projects. The purchase price for this acquisition was $1.5 million and the assets acquired consist primarily of intangible assets.

In late 2010, we began to decrease our investment in Maritech by suspending oil and gas property acquisitions, decreasing our development activities, exploring strategic alternatives to our ownership of Maritech and its oil and gas properties, and reviewing opportunities to sell Maritech oil and gas property packages. As part of this overall effort, in February and March 2011, Maritech sold certain properties, along with the associated decommissioning liabilities. As part of these transactions, Maritech paid an aggregate of

8

approximately $2.8 million after normal purchase price adjustments. These sold properties, in the aggregate, accounted for approximately 12% of Maritech’s proved reserves as of December 31, 2010.

On May 31, 2011, Maritech completed the sale of approximately 79% of its proved oil and gas reserves as of December 31, 2010, to Tana Exploration Company LLC (Tana), a subsidiary of TRT Holdings, Inc. (TRT), pursuant to a Purchase and Sale Agreement dated April 1, 2011. The sale was made to Tana for a base purchase price of $222.3 million. At the closing of the sale, Tana assumed approximately $72.7 million of associated asset retirement obligations, and Maritech received $173.3 million cash, representing the base purchase price less $11.1 million that consisted of a deposit that was paid in April 2011 and purchase price adjustments, including those adjustments reflecting cash flows subsequent to the January 1, 2011, effective date. The proceeds are subject to additional post-closing adjustments. As a result of the sale, we recorded a consolidated gain on sale of assets of $58.1 million. Due to Maritech’s continuing efforts to sell its remaining oil and gas properties, such properties have been reclassified to oil and gas properties held for sale, and their net book values have been adjusted to fair value. In connection with the sale of Maritech oil and gas producing properties, during the second quarter of 2011, we charged to general and administrative expenses approximately $2.7 million of employee retention and incentive benefits paid in connection with these sales.

In August 2011, Maritech sold an additional remaining oil and gas property in exchange for the purchaser assuming the associated decommissioning liability. The sold property represents approximately 3% of Maritech’s December 31, 2010 oil and gas reserves.

On July 20, 2011, we purchased a new heavy lift derrick barge (which we have named the TETRA Hedron) with a 1,600-metric-ton lift capacity, fully revolving crane. The vessel was purchased from Wison (Nantong) Heavy Industry Co., Ltd. and Nantong MLC Tongbao Shipbuilding Co., Ltd. for $62.8 million. Approximately $20.8 million of the purchase price is held in certain escrow accounts and will be released in accordance with the terms of the escrow agreements. The amount of remaining cash in escrow will be included in restricted cash on our consolidated balance sheet until the final release of escrow cash on April 30, 2014. The vessel was transported to the Gulf of Mexico during the third quarter and will be placed into service during the fourth quarter of 2011 following final outfitting and sea trials.

NOTE C – COMPRESSCO PARTNERS, L.P. INITIAL PUBLIC OFFERING

On June 20, 2011, our Compressco Partners, L.P. (Compressco Partners) subsidiary completed its initial public offering of 2,670,000 common units (representing a 17.3% limited partner interest) in exchange for $53.4 million of gross proceeds (the Offering). Following the issuance of an additional 400,500 units to us in July 2011 as a result of the expiration of an underwriters’ option to purchase additional common units, our ownership in Compressco Partners has been increased to 83.2%, including common units, subordinated units, and a 2% general partner interest. In connection with the Offering, certain of our wholly owned subsidiaries, including Compressco Partners GP Inc. (the General Partner), contributed substantially all of our Compressco segment’s wellhead compression-based production enhancement service business, operations, and related assets and liabilities to Compressco Partners and its wholly owned subsidiaries. In exchange, including the additional units issued in July 2011, Compressco Partners issued to us 6,427,257 common units (representing a 40.6% limited partner interest), 6,273,970 subordinated units (representing a 39.6% limited partner interests), an aggregate 2.0% general partner interest, and incentive distribution rights. Also, certain directors, executive officers, and other employees of the General Partner were then issued 157,870 restricted units (representing a 1.0% limited partner interest) granted pursuant to a long-term incentive plan. The issuance of the 2,670,000 common units in the Offering, at a $20 per unit Offering Price, resulted in Compressco Partners receiving $53.4 million of gross proceeds, $32.2 million of which was distributed to us to repay an intercompany loan balance. Approximately $11.1 million of the Offering proceeds was or will be used to satisfy Offering expenses, including underwriters’ discount and approximately $7.3 million that was paid to us by Compressco Partners to reimburse us for costs we incurred on their behalf. The contribution transactions described above represent transactions between entities under common control. Consequently, the contributed assets were recorded at our carrying value.

The contributions of the majority of the operations and related assets and liabilities of our Compressco segment were effected pursuant to the terms of a Contribution, Conveyance and Assumption Agreement (the Contribution Agreement). Compressco Partners is governed by the First Amended and

9

Restated Agreement of Limited Partnership (the Partnership Agreement). The Partnership Agreement requires Compressco Partners to distribute all of its available cash, as defined in the Partnership Agreement, to the holders of the common units, subordinated units, 2% general partner interest, and incentive distribution rights in accordance with the terms of the Partnership Agreement. The Partnership Agreement also provides for the management of Compressco Partners by the General Partner. The reimbursement of direct and indirect costs incurred by us in providing personnel and services on behalf of Compressco Partners, as well as other transactions between us and Compressco Partners, is governed by the terms of an Omnibus Agreement between us and Compressco Partners.

Following the Offering, as of September 30, 2011, the 16.8% portion of Compressco Partners owned by public unitholders is reflected as a noncontrolling interest in our consolidated financial statements.

Under the Partnership Credit Agreement, Compressco Partners, along with certain of its subsidiaries, are named as borrowers, and all obligations under the credit facility are guaranteed by all of Compressco Partners’ existing and future, direct and indirect, domestic subsidiaries. All obligations under the Partnership Credit Agreement are secured, subject to certain exceptions, by a first lien security interest in substantially all  of the assets (excluding real property) of Compressco Partners and its subsidiaries and all of the capital stock of the subsidiaries of Compressco Partners (with some limitations). The Partnership Credit Agreement includes borrowing capacity of $20.0 million, less $3.0 million that is required to be set aside as a reserve that cannot be borrowed. The facility is available for letters of credit (at a sublimit of $5.0 million) and includes an uncommitted $20.0 million expansion feature. The Partnership Credit Agreement will be used to fund Compressco Partners’ working capital needs, letters of credit, and for general partnership purposes, including capital expenditures and potential future acquisitions. So long as it is not in default, Compressco Partners may use its credit facility to fund its quarterly distributions. Borrowings under the Partnership Credit Agreement are subject to the satisfaction of customary conditions, including the absence of a default. As of September 30, 2011, there is no balance outstanding under the Partnership Credit Agreement.

NOTE E – DECOMMISSIONING AND OTHER ASSET RETIREMENT OBLIGATIONS

The large majority of our asset retirement obligations consists of the future well abandonment and decommissioning costs for offshore oil and gas facilities and platforms owned by our Maritech subsidiary, including the remaining abandonment, decommissioning, and debris removal costs associated with offshore platforms destroyed by hurricanes. The amount of decommissioning liabilities recorded by Maritech is reduced by amounts allocable to joint interest owners, anticipated insurance recoveries, and any contractual amount to be paid by the previous owner of the oil and gas property when the liabilities are satisfied.

10

The changes in the asset retirement obligations during the three month and nine month periods ended September 30, 2011 and 2010 are as follows:

	Three Months Ended September 30,
	2011			2010

Settlement of retirement obligations		(183,129	)		(68,046	)
Ending balance as of September 30	$	133,595		$	202,235

Revisions in estimated cash flows for the three months and nine months ended September 30, 2011, are primarily related to the retained Maritech facilities and platforms. Settlements of asset retirement obligations during the three months and nine months ended September 30, 2011, include approximately $3.3 million and $122.0 million, respectively, of obligations associated with oil and gas properties that were sold by Maritech during the periods.

NOTE F – HEDGE CONTRACTS

We are exposed to financial and market risks that affect our businesses. We have currency exchange rate risk exposure related to transactions denominated in a foreign currency as well as to investments in certain of our international operations. As a result of our variable rate bank credit facilities including the variable rate credit facility of Compressco Partners, to the extent we have debt outstanding, we face market risk exposure related to changes in applicable interest rates. We have concentrations of credit risk as a result of trade receivables owed to us by companies in the energy industry. In addition, we have market risk exposure in the sales prices we receive for the remainder of our oil and gas production. Our financial risk management activities may involve, among other measures, the use of derivative financial instruments, such as swap and collar agreements, to hedge the impact of market price risk exposures. Prior to the execution of the purchase and sale agreement in April 2011 pursuant to which we sold substantially all of our remaining Maritech oil and gas properties in May 2011, we utilized cash flow commodity hedge transactions to reduce our exposure related to the volatility of oil and gas prices. For these and other hedge contracts, we formally document all relationships between hedging instruments and hedged items, as well as our risk management objectives, our strategies for undertaking various hedge transactions, and our methods for assessing and testing correlation and hedge ineffectiveness. All hedging instruments are linked to the hedged asset, liability, firm commitment, or forecasted transaction. We also assess, both at the inception of the hedge and on an ongoing basis, whether the derivatives that are used in these hedging transactions are highly effective in offsetting changes in cash flows of the hedged items. As indicated below, these cash flow commodity hedge contracts were liquidated in the second quarter of 2011.

Derivative Hedge Contracts

In April 2011, following the execution of the purchase and sale agreement pursuant to which Maritech agreed to sell approximately 79% of its proved reserves as of December 31, 2010, we liquidated our remaining oil hedge contracts and paid $14.2 million to the counterparty. Therefore, during the three

11

months ended September 30, 2011, we had no remaining cash flow hedging swap contracts outstanding associated with our Maritech subsidiary’s oil or gas production.

 Pretax gains and losses associated with oil and gas derivative swap contracts are summarized below:

NOTE H – COMMITMENTS AND CONTINGENCIES

Litigation

We are named defendants in lawsuits and respondents in governmental proceedings arising in the ordinary course of business. While the outcome of lawsuits or other proceedings against us cannot be predicted with certainty, management does not reasonably expect these matters to have a material adverse impact on the financial statements.

Derivative Lawsuit

Between May 28, 2008 and June 27, 2008, two petitions were filed by alleged stockholders in the District Courts of Harris County, Texas, 133rd and 113th Judicial Districts, purportedly on our behalf. The suits name our directors and certain officers as defendants. The factual allegations in these lawsuits mirror those in a federal class action lawsuit which was settled during 2010. The claims are for breach of fiduciary duty, unjust enrichment, abuse of control, gross mismanagement, and waste of corporate assets. The petitions seek disgorgement, costs, expenses, and unspecified equitable relief. On September 22, 2008, the 133rd District Court consolidated these complaints as In re TETRA Technologies, Inc. Derivative Litigation, Cause No. 2008-23432 (133rd Dist. Ct., Harris County, Tex.), and appointed Thomas Prow and Mark Patricola as Co-Lead Plaintiffs. This lawsuit was stayed by agreement of the parties pending the Court’s ruling on our motion to dismiss the federal class action. On September 8, 2009, the plaintiffs in this state court action filed a consolidated petition which makes factual allegations similar to the surviving allegations in the federal lawsuit prior to it being settled. On April 19, 2010, the Court granted our motion to abate the suit, based on plaintiff’s inability to demonstrate derivative standing. On June 8, 2010, we received a letter from plaintiff’s counsel demanding that our board of directors take action against the defendants named in the previously filed derivative lawsuit. On August 22, 2011, the Court issued a Preliminary Approval Order preliminarily approving the settlement of the suit as set forth in the Stipulation of Settlement dated August 12, 2011 (the Stipulation). The Stipulation does not provide for the payment of monetary compensation to stockholders; rather, it provides for certain additions to our corporate governance policies and procedures and for the payment of plaintiff’s attorneys’ fees and litigation expenses, which will be paid by our insurers. On October 17, 2011, the Court granted final approval of the settlement.

Environmental

One of our subsidiaries, TETRA Micronutrients, Inc. (TMI), previously owned and operated a production facility located in Fairbury, Nebraska. TMI is subject to an Administrative Order on Consent issued to American Microtrace, Inc. (n/k/a/ TETRA Micronutrients, Inc.) in the proceeding styled In the Matter of American Microtrace Corporation, EPA I.D. No. NED00610550, Respondent, Docket No. VII-98-H-0016, dated September 25, 1998 (the Consent Order), with regard to the Fairbury facility. TMI is liable for future remediation costs and ongoing environmental monitoring at the Fairbury facility under the Consent Order; however, the current owner of the Fairbury facility is responsible for costs associated with the closure of that facility.

NOTE I – INDUSTRY SEGMENTS

We manage our operations through five operating segments: Fluids, Offshore Services, Maritech, Production Testing, and Compressco.

Our Fluids Division manufactures and markets clear brine fluids, additives, and other associated products and services to the oil and gas industry for use in well drilling, completion, and workover operations in the United States and in certain countries in Latin America, Europe, Asia, the Middle East, and Africa. The Division also markets liquid and dry calcium chloride products manufactured at its production facilities to a variety of markets outside the energy industry.

Our Offshore Division consists of two operating segments: Offshore Services and Maritech, an oil and gas exploration, exploitation, and production segment. The Offshore Services segment provides (1) downhole and subsea oil and gas services such as well plugging and abandonment, workover, and wireline services, (2) decommissioning and certain construction services utilizing heavy lift barges and various

14

cutting technologies with regard to offshore oil and gas production platforms and pipelines, and (3) conventional and saturated air diving services.

The Maritech segment consists of our Maritech subsidiary, which is an oil and gas exploration, development, and production operation focused in the offshore and onshore U.S. Gulf Coast region. As a result of certain sales transactions during the first nine months of 2011, including the May 31, 2011, sale of a significant portion of Maritech’s oil and gas properties, Maritech has sold approximately 95% of its proved reserves as of December 31, 2010. Maritech’s remaining operations consist primarily of the ongoing abandonment and decommissioning associated with its remaining offshore facilities and production platforms. Maritech intends to acquire a significant portion of these services from the Offshore Division’s Offshore Services segment.

Our Production Enhancement Division consists of two operating segments: Production Testing and Compressco. The Production Testing segment provides production testing services in many of the major oil and gas basins in the United States, as well as certain onshore basins in certain regions in Mexico, Brazil, Northern Africa, the Middle East, and other international markets.

The Compressco segment provides wellhead compression-based and other production enhancement services throughout many of the onshore producing regions of the United States, as well as certain onshore basins in Canada, Mexico, South America, Europe, Asia, and other international locations. Beginning June 20, 2011, following Compressco Partners’ initial public offering, we allocate and charge certain corporate and divisional direct and indirect administrative costs to Compressco Partners.

We generally evaluate performance and allocate resources of our segments based on profit or loss from operations before income taxes and nonrecurring charges, return on investment, and other criteria. Transfers between segments and geographic areas are priced at the estimated fair value of the products or services as negotiated between the operating units. “Corporate overhead” includes corporate general and administrative expenses, corporate depreciation and amortization, interest income and expense, and other income and expense.

Summarized financial information concerning the business segments from continuing operations is as follows:

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

Business Overview

Following the strategic steps taken earlier this year, we believe we are well-positioned to further advance our plans for future growth. The May 2011 sale of a significant portion of our Maritech oil and gas producing properties for a net purchase price of approximately $184.4 million, along with other Maritech property sales, has essentially removed us from the oil and gas exploration and production business and provided capital available to fund our growing energy service businesses. The July 2011 purchase of a $62.8 million heavy lift derrick barge with a 1,600-metric-ton lift capacity, fully revolving crane will enable our Offshore Services segment to significantly increase its heavy lift capacity and enable us to serve customers with heavier structures. We expect to place this vessel into service in the Gulf of Mexico during the fourth quarter of 2011. Our available borrowing capacity under our revolving credit facilities, together with our available cash and our potential to access additional capital resources, equips us in pursuing suitable acquisition opportunities. Approximately $19.6 million of our consolidated cash balance is held by our Compressco Partners, L.P. subsidiary and is solely available for its purposes as a separate publicly held limited partnership.

The current strong demand for domestic onshore oil and gas services has significantly benefitted our Production Testing and Fluids segments, as each of these businesses seek to capitalize on the growth in domestic onshore drilling activity, particularly shale field activity. In addition, international demand, particularly in Mexico, has also strengthened. As a result, revenues and profitability for these segments have increased compared to the prior year period. Our Fluids segment has also reported improved profitability from its manufactured chemicals operations, as continuing efficiencies in our El Dorado, Arkansas, calcium chloride facility have been realized compared to the prior year. Partially offsetting the increases in our onshore businesses, the performance of our offshore businesses, including our Offshore Services segment and the offshore portion of our Fluids segment, has reflected the continuing sluggish demand for services in the U.S. Gulf of Mexico, although offshore activity has improved compared to the third quarter of 2010. However, drilling activity levels continue to lag pre-Macondo spill levels, and the

17

demand for offshore well abandonment and decommissioning services has been soft, despite new regulations issued last year. The sales of Maritech oil and gas properties discussed above have significantly reduced revenues from this segment, and excess decommissioning charges during the current year quarter associated with Maritech’s remaining asset retirement obligations also affected our profitability for the period.

Critical Accounting Policies

There have been no material changes or developments in the evaluation of the accounting estimates and the underlying assumptions or methodologies pertaining to our Critical Accounting Policies and Estimates disclosed in our Form 10-K for the year ended December 31, 2010. In preparing our consolidated financial statements, we make assumptions, estimates, and judgments that affect the amounts reported. We periodically evaluate these estimates and judgments, including those related to potential impairments of long-lived assets (including goodwill), the collectability of accounts receivable, and the cost of future abandonment and decommissioning obligations. Our estimates are based on historical experience and on future expectations that we believe are reasonable. The fair values of large portions of our total assets and liabilities are measured using significant unobservable inputs. The combination of these factors forms the basis for judgments made about the carrying values of assets and liabilities that are not readily apparent from other sources. These judgments and estimates may change as new events occur, as new information is acquired, and as changes in our operating environments are encountered. Actual results are likely to differ from our current estimates, and those differences may be material.

Consolidated revenues for the quarter ended September 30, 2011, decreased compared to the prior year period due to a reduction in revenues from our Maritech segment, which sold approximately 95% of its December 31, 2010 proved oil and gas reserves during the first eight months of the current year. These sales of oil and gas properties will significantly reduce Maritech segment revenues going forward and Maritech continues to seek buyers for its remaining producing properties. This decrease in Maritech revenues was partially offset by increased revenues for our Production Testing, Fluids, and Compressco segments. Our Production Testing segment reported increased revenues and gross profit, driven primarily

18

by strong demand domestically. Our Fluids Division also reported increased revenues and gross profit due to increased CBF sales, both domestically and internationally, including increased offshore Gulf of Mexico activity compared to the prior year period, although offshore activity levels continue to lag pre-Macondo levels. Gross profit of the Fluids Division was also positively affected by improved efficiencies in its chemicals manufacturing business. Compressco revenues and gross profit increased, primarily due to increased sales of compressor units and improving activity levels. Our Offshore Services segment revenues were down slightly, partly due to overall decreased pricing that also contributed to the segment’s decreased profitability. Maritech gross profit decreased due to the sales of properties earlier in the year and increased excess decommissioning costs charged to earnings.

Consolidated general and administrative expenses increased during the third quarter of 2011 compared to the prior year period due, in part, to approximately $1.8 million of increased employee-related costs. In addition, general and administrative expenses increased due to approximately $0.7 million of increased professional fee expenses, approximately $0.5 million of increased office expenses, and $0.4 million of increased insurance expenses. These increases were partially offset by approximately $0.4 million of decreased bad debt expense.

Net consolidated interest expense decreased slightly during the third quarter of 2011 as compared to the prior year period due to increased interest income on invested cash during the period. Proceeds from the sale of Maritech properties during the second quarter of 2011 contributed to significant cash balances during the third quarter of 2011.

We recognized a consolidated loss on sales of properties as compared to a consolidated gain on sales of assets during the prior year period primarily due to adjustments to the gains on Maritech property sales during the current year period.

Other expense increased during the third quarter of 2011 compared to the prior year period, primarily due to approximately $0.8 million of decreased earnings from an unconsolidated joint venture and despite approximately $0.5 million of decreased foreign currency losses.

Our provision for income taxes during the third quarter of 2011 increased due to increased earnings compared to the prior year period.

The increase in Fluids Division revenues during the third quarter of 2011 compared to the prior year period was primarily due to $4.9 million of increased product sales revenues. This increase was due to increased revenue from sales of clear brine fluids (CBFs), both domestically and internationally. Domestically, the increase was due to increased onshore product sales and the slow but steady ongoing recovery of our offshore operations, which was severely impacted during the third quarter of 2010 following the April 2010 Macondo accident. International activity primarily reflects the increased activity in Brazil. 

19

These increases in CBF sales offset the performance of our chemicals operations, which reflected flat revenues compared to the prior year period despite increased sales in Europe. Increased onshore domestic activity levels contributed to the approximately $2.7 million of increased service revenues, including increased revenues from frac water services.

Our Fluids Division gross profit increased compared to the prior year period, primarily as a result of improved efficiencies at our El Dorado, Arkansas, plant. During the prior year period, we reflected higher product costs, early production inefficiencies from the plant, and the impact of decreased oil and gas industry demand. We continue to take steps to improve the operational efficiency of this plant, which are expected to result in continued incremental improvement in plant performance going forward. Associated with these plant operational inefficiencies, in March, 2011, we filed a lawsuit in Union County, Arkansas, seeking to recover damages related to certain design and other services provided in connection with the construction of the El Dorado plant. In addition to the increased gross profit from the El Dorado plant, gross profit from service activities also increased due to the increase in domestic activity levels discussed above.

Fluids Division income before taxes increased compared to the prior year period due to the increase in gross profit discussed above. Increased administrative costs, primarily due to increased professional fees and personnel-related costs, were offset by increased other income.

Revenues from our Offshore Services segment decreased slightly during the third quarter of 2011 compared to the prior year quarter. Increased offshore well abandonment and decommissioning revenues were offset by the impact of the May 2011 sale of our onshore well abandonment operations, decreased diving and cutting service activities, and an overall softer pricing environment. During 2010, the BOEMRE issued NTL 2010-G05, the “Idle Iron Guidance” regulations, which require that wells located in federal waters must be permanently plugged within three years of becoming uneconomic to operate and that platforms and other infrastructure must be removed within five years of becoming uneconomic to operate. We anticipate that these regulations will increase the future demand for offshore well abandonment and decommissioning services. In July 2011, we purchased a new heavy lift derrick barge (which we have named the TETRA Hedron) with a 1,600-metric-ton lift capacity, fully revolving crane. With this vessel, which we expect to place into service in the Gulf of Mexico during the fourth quarter of 2011, our Offshore Services segment will significantly increase its heavy lift capacity, enabling us to better serve the Gulf of Mexico decommissioning market and to serve customers with heavier structures. Approximately $16.6 million of Offshore Services revenues was from work performed for Maritech during the third quarter of 2011, compared to $28.0 million of such work in the prior year period. These intercompany revenues are eliminated in consolidation. Despite the sale of a large majority of Maritech’s oil and gas producing properties, a significant amount of abandonment and decommissioning work remains for Maritech.

Gross profit for the Offshore Services segment during the third quarter of 2011 decreased as compared to the prior year period, primarily due to overall decreased profitability primarily as a result of the 

20

soft pricing environment and decreased diving and cutting services activity levels discussed above. In addition, the impact of increased activity for our offshore well abandonment and decommissioning operations was more than offset by increased costs, approximately $3.2 million of which related to due diligence and start up costs associated with the new heavy lift derrick barge we purchased in July 2011. Due to the anticipated increased activity as a result of the “Idle Iron Guidance” regulations discussed above, we anticipate that pricing and profitability for many of the Offshore Services segment operations will increase going forward.

Offshore Services income before taxes decreased due to the decrease in gross profit described above and due to increased other expense, which was primarily due to an asset disposal gain during the prior year period.

Maritech revenues decreased significantly during the third quarter of 2011 compared to the prior year period due to the sale of approximately 95% of its December 31, 2010 oil and gas reserves during the first eight months of 2011. In particular, the May 31, 2011, sale of oil and gas properties to Tana resulted in the sale of approximately 79% of Maritech’s December 31, 2010 proved reserves. Following the above mentioned sales of producing properties, Maritech revenues are expected to continue to be minimal going forward.

Despite the significant decrease in revenues discussed above, the impact on Maritech gross profit during the third quarter of 2011 was largely offset by decreased operating and depletion expenses associated with the sold properties. In addition to the decreased operating and depletion expenses compared to the prior year period, Maritech reported approximately $14.3 million of oil and gas property impairments during the prior year quarter, compared to none during the current year period. These decreased operating expenses were partially offset by approximately $6.3 million of increased excess decommissioning costs. The increased excess decommissioning costs were associated with asset retirement obligations on nonproductive properties retained by Maritech. A large portion of these current period excess decommissioning costs were associated with properties not operated by Maritech. Maritech continues to perform significant decommissioning work on its remaining offshore platforms, and additional charges for decommissioning costs in excess of estimates may occur in future periods.

Maritech loss before taxes during the third quarter of 2011 increased compared to the prior year period due to the decrease in gross profit discussed above. Decreased general and administrative expenses as a result of the decreased workforce following the property sales were largely offset by decreased other income, primarily due to adjustments to the gains on property sales.

Production Testing revenues increased during the third quarter of 2011 compared to the prior year period, primarily due to an increase of approximately $9.0 million in domestic revenues. This increase was a result of increased domestic onshore oil and gas drilling activity, as reflected by rig count data. In addition, international revenues increased by approximately $2.7 million, primarily due to increasing activity in Mexico. We expect domestic and Mexican activity levels to continue to be strong in the near term.

The increase in Production Testing gross profit during the second quarter of 2011 was primarily due to the increased domestic activity discussed above. However, gross profit on international operations also increased due to the increased activity in Mexico.

Production Testing income before taxes increased due to the increased gross profit discussed above, but was partially offset by increased administrative expenses and decreased other income. Administrative expenses increased primarily due to increased salaries and employee-related costs. Other income decreased, mainly due to decreased earnings from an unconsolidated joint venture.

The increase in Compressco revenues during the third quarter of 2011 compared to the prior year period was due to an increase of approximately $2.5 million of revenues from sales of compressor units and parts. This increase was primarily due to sales to specific customers pursuant to large on-going purchase programs. Compressco service revenue increased by approximately $2.4 million, due to increased domestic demand for compression services as well as increased activity in Mexico. Activity levels in Mexico are expected to continue to be strong going forward, although Compressco was negatively affected by

22

conditions in Mexico during the previous year due to customer budgetary issues and security disruptions. Compressco’s future activity levels in Mexico could continue to be affected by these issues. Compressco continues to operate at reduced levels of fabrication of new compressor units and expects to do so until demand for its services increases and inventories of available units are reduced.

Compressco gross profit increased during the third quarter of 2011 compared to the prior year period primarily due to the sales of compressor units discussed above. In addition, profitability of Compressco’s domestic and Mexican operations have also increased. Domestic gross profit increased partly due to continuing efforts to reduce operating expenses.

Income before taxes for Compressco decreased during the third quarter of 2011 compared to the prior year period, despite the increased gross profit discussed above. Compressco administrative expenses increased primarily due to increased professional fee expenses and allocated employee-related costs. As a consequence of the June 20, 2011, initial public offering by Compressco Partners, administrative expenses for the Compressco segment have increased as a result of professional fee expenses, increased administrative staff associated with being a separate public limited partnership, and the allocation of a portion of our corporate administrative expenses to Compressco Partners pursuant to the Omnibus Agreement. In addition, the Compressco segment had increased other expense due to foreign currency losses.

Corporate Overhead includes corporate general and administrative expense, interest income and expense, and other income and expense. Such expenses and income are generally not allocated to our operating divisions, as they relate to our general corporate activities. However, in connection with the public offering of common units in our Compressco Partners subsidiary, on June 20, 2011 we began allocating and charging Compressco Partners for its share of our corporate administrative costs directly related to Compressco Partners’ activities. Corporate Overhead increased during the third quarter of 2011 compared to the prior year period due to increased corporate administrative costs. This increase in corporate general and administrative costs was due to approximately $0.3 million of increased office expenses and $0.3 million of increased professional and insurance expenses. Net interest expense decreased primarily due to increased interest income on invested cash balances. Other expenses also decreased primarily due to approximately $0.4 million of decreased foreign currency losses.

Consolidated revenues for the nine months ended September 30, 2011 decreased compared to the prior year period despite the growth in revenues from each of our segments other than Maritech. In particular, revenues from our Fluids segment increased due to increased international CBF sales activity in the regions we serve as well as increased calcium chloride sales activity, both domestically and internationally. Our Production Testing segment also reported increased revenues, primarily due to increased domestic onshore activity. Our Compressco and Offshore Services segments also reported increased activity. These increases were offset by decreased revenues from our Maritech segment. The decrease in Maritech revenues was primarily caused by the sale during the first eight months of 2011 of approximately 95% of its proved oil and gas reserves as of December 31, 2010. Overall gross profit decreased primarily due to higher excess decommissioning costs incurred by Maritech, although Offshore Services gross profit also decreased. These decreases were partially offset by increased gross profit from our Production Testing and Fluids segments.

Consolidated general and administrative expenses increased during the first nine months of 2011 compared to the prior year period due to approximately $5.7 million of increased salaries, benefits, and other employee-related costs. In addition, general and administrative expenses also increased, due to approximately $2.2 million of increased professional fee expenses, and $1.9 million of increased bad debt expense, primarily due to the reversal of $1.0 million of bad debt expense during the prior year period. In addition, insurance, taxes, and other general expenses increased by approximately $2.3 million.

Net consolidated interest expense decreased during the first nine months of 2011 primarily due to increased interest income resulting from increased cash investments.

Consolidated gains on sales of assets increased significantly during the first nine months of 2011, primarily due to the sale of Maritech oil and gas producing properties, particularly the May 2011 sale of properties to Tana. The aggregate consolidated net gain on these sales of properties during the current year period was approximately $58.5 million.

Consolidated other expense was $14.7 million during the first nine months of 2011 compared to $1.9 million of other income during the prior year period. Other expense during the current year period was due to the $14.2 million charge to expense upon the liquidation of commodity derivative swap contracts in connection with the decision to sell Maritech oil and gas producing properties. In addition, current year other

24

expense includes approximately $1.9 million of decreased foreign currency gains and approximately $0.5 million of decreased earnings from unconsolidated joint ventures compared to the prior year period.

Our provision for income taxes during the first nine months of 2011 increased due to our increased earnings during the current year period compared to the prior year period.

The increase in Fluids Division revenues during the first nine months of 2011 compared to the prior year period was primarily due to $18.9 million of increased product sales revenues. This increase was due to $8.9 million of increased CBF product sales revenues, as increased activity internationally, particularly in Brazil, more than offset a decrease in domestic activity. Domestic offshore activity levels continue to be reduced as a result of the uncertain regulations governing offshore drilling activities following the April 2010 Macondo accident. Also contributing to the increased revenues was $10.0 million of increased sales of calcium chloride and other manufactured products, primarily from our El Dorado, Arkansas, calcium chloride plant. In addition, European calcium chloride sales revenues also contributed to this increase. Increased onshore domestic activity levels resulted in approximately $9.2 million of increased service revenues, including increased revenues from frac water services.

Our Fluids Division gross profit increased compared to the prior year period, primarily as a result of the increased gross profit from our chemicals manufacturing operations, both in Europe and from our El Dorado, Arkansas, plant, which continues to improve the efficiency of its operations. In addition, during the prior year period, we reflected certain startup costs associated with the El Dorado plant, which began operations in late 2009. We continue to take steps to improve the operational efficiency of this plant, which are expected to result in continued incremental improvement in plant performance going forward. Associated with these plant operational inefficiencies, in March 2011, we filed a lawsuit in Union County, Arkansas, seeking to recover damages related to certain design and other services provided in connection with the construction of the El Dorado plant. In addition to the improved gross profit from our chemicals manufacturing operations, sales of CBFs also generated increased gross profit, as the increased international activity discussed above more than offset decreased profitability domestically.

Fluids Division income before taxes increased compared to the prior year period due to the increase in gross profit discussed above, and despite increased administrative costs and a decrease in other income. Fluids Division administrative costs increased mainly due to increased professional fees and personnel-related costs.

Revenues from our Offshore Services segment increased during the first nine months of 2011 compared to the prior year period. Increased offshore well abandonment and decommissioning revenues were largely offset by decreased cutting services and diving services activity and a softer pricing environment. In addition, during May 2011, we sold our onshore abandonment operations, although this sale is not expected to significantly reduce our revenues in the future. During 2010, the BOEMRE issued NTL 2010-G05, the “Idle Iron Guidance” regulations, which require that wells located in federal waters be permanently plugged within three years of becoming uneconomic to operate and that platforms and other infrastructure must be removed within five years of becoming uneconomic to operate. We anticipate that these regulations will increase the future demand for well abandonment and decommissioning services to be performed by our Offshore Services segment. In July 2011, we purchased a new heavy lift derrick barge (which we named the TETRA Hedron) with a 1,600-metric-ton lift capacity, fully revolving crane. With this vessel, which we expect to place into service in the Gulf of Mexico during the fourth quarter of 2011, our Offshore Services segment will significantly increase its heavy lift capacity, enabling us to better serve the Gulf of Mexico decommissioning market and to serve customers with heavier structures. Still, we anticipate that levels of Offshore Services segment activity going forward will continue to be lower than the record activity levels we experienced during 2009. Approximately $50.7 million of Offshore Services revenues were from work performed for Maritech during the first nine months of 2011, compared to $51.3 million of such work in the prior year period. These intercompany revenues are eliminated in consolidation. Despite the sale of Maritech’s oil and gas producing properties, a significant amount of abandonment and decommissioning work remains for Maritech.

Gross profit for the Offshore Services segment during the first nine months of 2011 decreased as compared to the prior year period primarily due to decreased profitability of our cutting services and diving services operations and despite increased profitability of our decommissioning operations. A portion of the decrease in gross profit was caused by approximately $5.5 million of due diligence, inspection, and start up costs incurred during the first nine months of 2011 associated with the new heavy lift derrick barge we purchased in July 2011. Overall segment profitability was also affected by a lower pricing environment during the current year period. Due to the anticipated increased activity as a result of the “Idle Iron Guidance” regulations discussed above, we anticipate that pricing and profitability of many of the Offshore Services segment operations will increase going forward.

Offshore Services segment income before taxes decreased due to the decrease in gross profit described above despite decreased administrative expenses, which resulted primarily from decreased salaries and employee-related costs. The decreased gross profit also more than offset the increase in other income, which was primarily generated from the sale of onshore abandonment operations during the second quarter of 2011.

Maritech revenues decreased during the first nine months of 2011 compared to the prior year period, primarily due to the sale during the current year period of approximately 95% of Maritech’s total proved oil and gas reserves as of December 31, 2010. The most significant sale of oil and gas producing properties was on May 31, 2011, when Maritech completed the sale to Tana of oil and gas properties that collectively represented approximately 79% of Maritech’s December 31, 2010 total proved reserves. As a result of these sales, decreased production volumes resulted in decreased revenues of approximately $49.8 million. In addition to the impact of decreased production, Maritech revenues decreased approximately $15.5 million due to decreased realized prices of Maritech’s natural gas production. Maritech had previously hedged a portion of its expected production cash flows by entering into derivative hedge contracts and its contracts hedging its oil production extended through 2011. However, Maritech’s natural gas hedges expired at the end of 2010. Maritech’s average natural gas price received during the first nine months of 2011 was $4.35/MMBtu compared to the $8.48/MMBtu average realized price received during the prior year period. In April 2011, in connection with the planned sale of oil and gas producing properties to Tana, we liquidated the oil derivative hedge contracts. As a result, beginning April 2011, Maritech’s remaining oil and gas production cash flows are no longer hedged. Including the impact of its oil hedge contracts through March 2011, Maritech reflected average realized oil prices during the first nine months of 2011 of $104.12/barrel compared to $96.60/barrel during the prior year period. Following the above mentioned sales of producing properties, Maritech revenues are expected to be minimal going forward.

Maritech gross profit decreased significantly during the first nine months of 2011 compared to the prior year period due to the decreased revenues discussed above, despite the decrease in operating and depletion expenses as a result of the sold properties. Although oil and gas property impairments decreased approximately $10.6 million, this decrease was more than offset by approximately $23.9 million of increased excess decommissioning costs. A large portion of the excess decommissioning costs recorded during the current year period was associated with properties not operated by Maritech. In addition, Maritech recorded approximately $1.7 million of insurance settlement gains during the prior year period as a result of settlement and claim proceeds from Hurricane Ike damages. Maritech continues to perform significant decommissioning work on its remaining offshore facilities and platforms, and additional charges for decommissioning costs in excess of estimates may occur in future periods.

Despite the decrease in gross profit discussed above, Maritech income before taxes during the first nine months of 2011 increased significantly compared to the prior year period due to approximately $56.6 million ($58.5 million consolidated) of net gains on sales of properties during the current year period associated with the above described sales of producing properties. Partially offsetting this increase in gain on sale was the increase in administrative expenses, primarily due to $0.5 million of salary and employee related expenses, as the decrease in administrative staff during the third quarter of 2011 was more than offset by retention and incentive compensation incurred earlier in the year associated with the sale of Maritech properties. In addition, administrative expense includes an $0.6 million increase in bad debt expenses, primarily due to a prior year period reversal of bad debt expense.

Production Testing revenues increased during the first nine months of 2011 due to an increase of approximately $24.4 million in domestic revenues. This increase was a result of increased domestic onshore oil and gas drilling activity, as reflected by rig count data. In addition, international revenues increased by approximately $1.8 million, as decreased revenues associated with a South American technical management contract were more than offset by revenues from increased Mexico activity.

The increase in Production Testing gross profit during the first nine months of 2011 was primarily due to the increased domestic activity discussed above and the increased efficiencies at the higher activity levels. Gross profit on international Production Testing operations also increased during the nine month period primarily due to increased profitability on the South American technical management contract, despite the decreased revenues from the contract.

Production Testing income before taxes increased due to the increased gross profit discussed above. These increases were partially offset by increased administrative expenses primarily from increased salary and other employee-related costs during the 2011 period. In addition, the Production Testing segment reflected increased office and professional fees, as well as increased bad debt expense, particularly associated with the segment’s Libyan operations. Other income decreased due to approximately $0.2 million of decreased foreign currency losses.

The increase in Compressco revenues was due to an increase of approximately $4.8 million of revenues from sales of compressor units and parts during the first nine months of 2011 compared to the prior year period. This increase was primarily due to sales of compressor units to specific customers

28

pursuant to large and on-going purchase programs. Compressco service revenue increased by approximately $3.2 million primarily due to increased domestic demand for compression services. To a lesser extent, service revenue also increased due to increased international demand, particularly in Mexico, where demand is expected to further increase going forward. Compressco’s continuing growth could be negatively affected by conditions in Mexico, where customer budgetary issues and security disruptions have reduced activity levels. Compressco continues to operate at reduced levels of fabrication of new compressor units and expects to do so until demand for its services increases and inventories of available units are reduced.

Compressco gross profit decreased during the first nine months of 2011 compared to the prior year period primarily due to its domestic operations, where increased operating expenses hampered profitability. These decreases in domestic gross profit were partially offset by increased international gross profit, resulting from the increased activity level discussed above. The decreased domestic gross profit was due to increased costs incurred, particularly during the first half of 2011. Our Compressco segment continues to seek ways to reduce its operating expenses in the future.

Income before taxes for Compressco decreased during the first nine months of 2011 compared to the prior year period, primarily due to increased administrative expense. Compressco administrative expenses increased primarily due to increased professional fee expenses and allocated employee-related costs. Also as a consequence of Compressco Partners’ initial public offering, administrative expenses for the Compressco segment have increased as a result of professional fee expenses and increased administrative staff associated with being a separate public limited partnership and the allocation of a portion of our corporate administrative expenses to Compressco Partners pursuant to the Omnibus Agreement. In addition, the Compressco segment had increased other expense primarily due to increased foreign currency losses.

Corporate Overhead includes corporate general and administrative expense, interest income and expense, and other income and expense. Such expenses and income are generally not allocated to our operating divisions, as they relate to our general corporate activities. However, in connection with the public offering of common units in our Compressco Partners subsidiary, on June 20, 2011 we began allocating and charging Compressco Partners for its share of our corporate administrative costs directly related to Compressco Partners’ activities. Corporate Overhead increased significantly during the first nine months of 2011 compared to the prior year period, primarily due to increased other expense which resulted from approximately $14.2 million of increased hedge ineffectiveness loss. This increased hedge ineffectiveness loss was due to the April 2011 liquidation of hedge derivative contracts, following the planned sale of a significant portion of Maritech oil and gas producing properties, which resulted in a $14.2 million charge to corporate other expense for hedge ineffectiveness. In addition, other expense increased due to approximately $1.0 million of decreased foreign currency gains. Corporate administrative costs increased due to approximately $0.8 million of increased salaries and other general employee expenses and approximately $0.9 million of increased insurance and tax expenses. These increases were partially offset by approximately $0.4 million of decreased professional fee expenses.

Liquidity and Capital Resources

Following the sales of Maritech properties, the June 2011 initial public offering of our Compressco Partners subsidiary, and the July 2011 purchase of the heavy lift barge, we had consolidated cash of approximately $224.9 million as of September 30, 2011. Approximately $19.6 million of this cash balance is held by Compressco Partners and is unavailable for our general purposes. The sale of approximately 95% of Maritech oil and gas reserves generated approximately $181.5 million of net cash proceeds, primarily from the May 2011 sale of properties to Tana. These sales of Maritech properties have significantly changed our liquidity position and the nature of our cash flows from operating and investing activities; however, Maritech has retained approximately $125.9 million of decommissioning liabilities, and performing this decommissioning work will continue to represent a significant use of our cash provided from operations over the next two years. The June 2011, initial public offering by our Compressco Partners subsidiary generated approximately $42.3 million of proceeds to Compressco Partners, net of offering expenses. From these proceeds, Compressco Partners used $32.2 million to repay to us certain intercompany note balances. Following the offering, we continue to consolidate Compressco Partners as part of our Compressco segment in our consolidated financial statements; however, separate cash balances are now maintained by Compressco Partners to satisfy its operating requirements as well as to fund quarterly distributions pursuant to its partnership agreement.

During 2011, we have made significant investments in our Offshore Services and Production Testing segments in anticipation of future growth, and we plan to make additional capital expenditure investments as needed for each of our businesses, excluding Maritech. The timing of these planned capital expenditures will be managed in light of the current economic uncertainty, as well as the ongoing regulatory uncertainty faced by many of our offshore Gulf of Mexico customers. With the exception of the July 2011 purchase of a heavy lift derrick barge that was funded from our available cash, our recent capital expenditure activity has been funded from our operating cash flows. Our financial resources include available cash, future operating cash flows, borrowing capacity under our bank revolving credit facilities, and additional debt and equity financing capacity. Our strategy to grow our remaining businesses includes the utilization of these financial resources to grow our businesses organically and pursue suitable acquisitions.

Operating Activities

Cash flows generated by operating activities totaled approximately $48.4 million during the first nine months of 2011 compared to $119.4 million during the prior year period, a decrease of $71.0 million or 59.5%. Approximately $39.8 million of this decrease was from prior period operating cash flows that were generated from insurance settlements and claims proceeds from a portion of Maritech’s insurance coverage related to damages suffered from Hurricane Ike during 2008. The remaining decrease in operating cash flows during 2011 was due to decreased earnings excluding the gain on sales of assets during the current year period.

Operating cash flows for our offshore Gulf of Mexico operations continue to be negatively affected by the continuing regulatory uncertainties and delays that have followed the April 2010 Macondo oil spill in the U.S. Gulf of Mexico. As a result of the Macondo oil spill, regulatory requirements for offshore operators, particularly deepwater operators, have increased. Although the deepwater drilling moratorium was lifted in October 2010, the impact of regulatory uncertainty is expected to continue to negatively affect the cost and timing of offshore activities in the future, perhaps significantly. Although offshore rig count levels in the U.S. Gulf of Mexico have continued to increase during the past twelve months, they are still below pre-Macondo spill levels. Future operating cash flows for the offshore activities of our Fluids and Offshore Services segments will continue to be largely dependent upon the level of offshore oil and gas industry activity in the U.S. Gulf of Mexico region. For certain of our businesses, increased government regulations could affect us positively. However, to the extent more stringent government regulations affecting deepwater and shallow water drilling are enacted, our future revenues and operating cash flows could be negatively affected overall.

Offshore well abandonment and decommissioning operations in the U.S. Gulf of Mexico are governed by NTL 2010-G05 “Idle Iron Guidance” regulation, which requires that wells must be plugged within three years of becoming uneconomic and platform and other infrastructure must be removed within five years of becoming uneconomic to operate. Previously, the requirement was to perform this work after

30

the last well in a field was depleted. The BOEMRE identified approximately 3,500 nonproducing wells and 650 oil and gas production platforms that meet the new criteria currently. In October 2011, the BOEMRE’s responsibilities were divided between the Bureau of Ocean Energy Management (BOEM) and the Bureau of Safety and Environmental Enforcement (BSEE), which will oversee the provisions of the “Idle Iron Guidance.” These “Idle Iron Guidance” requirements are expected to increase the future demand for the abandonment and decommissioning services of our Offshore Services segment.

As of September 30, 2011, and following the sale of substantially all of Maritech’s producing oil and gas properties, the estimated third-party discounted fair value, including an estimated profit, of Maritech’s decommissioning liabilities totals $125.9 million, and our future operating cash flow will continue to be affected by the actual timing and amount of these decommissioning expenditures. During the three and nine months ended September 30, 2011, Maritech expended approximately $22.6 million and $66.1 million, respectively, on well abandonment and decommissioning work performed. Approximately $109.0 million of the cash outflow necessary to extinguish Maritech’s remaining decommissioning liabilities is expected to occur prior to September 30, 2012. Maritech’s remaining decommissioning liabilities relate primarily to the inventory of abandonment and decommissioning work, including an estimated profit margin, to be completed over the next two years. Our Offshore Services segment is expected to perform the significant majority of this work. The amount and timing of the cash outflows associated with all of Maritech’s remaining decommissioning liabilities are estimated based on expected costs and project scheduling. Such estimates are imprecise and subject to change due to changing cost estimates, further changes to BSEE requirements, and other factors.

In some cases, the previous owners of the properties that were acquired by Maritech are contractually obligated to pay Maritech a fixed amount for the future well abandonment and decommissioning work on these properties as the work is performed, which partially offsets Maritech’s future expenditures. Maritech’s estimated decommissioning liabilities are net of amounts allocable to joint interest owners and any contractual amounts to be paid by the previous owners of the properties. As of September 30, 2011, Maritech’s total undiscounted decommissioning obligation is approximately $134.7 million and consists of Maritech’s total liability of $125.4 million plus $9.3 million of such contractual reimbursement arrangements with the previous owners. An additional $12.1 million of such contractual reimbursement arrangements as of September 30, 2011, is classified as receivable assets related to amounts waiting to be invoiced and collected.

While the overall global economy continues to be difficult to predict, industry rig count and other data indicates that domestic oil and gas industry spending is increasing, spurred by the current strong pricing for crude oil and the recent trends for onshore shale exploitation. Demand for a large portion of our products and services is driven by oil and gas drilling and production activity, which is affected by oil and natural gas commodity pricing. In particular, our Production Testing and Fluids segments reported increased domestic onshore activity levels during the last half of 2010 and the first nine months of 2011. We are anticipating similar increases in revenues and cash flows for these businesses throughout the remainder of 2011; however, these anticipated increases are expected to continue to be significantly below the levels generated by these businesses during the first half of 2008.

During the past two years, Maritech has performed an extensive amount of well intervention, abandonment, decommissioning, debris removal, and platform construction associated with six offshore platforms that were destroyed by Hurricanes Rita and Ike during 2005 and 2008, respectively. As of September 30, 2011, Maritech has remaining work associated with two of the downed platforms. The estimated cost to perform the remaining abandonment, decommissioning, and debris removal is approximately $33.1 million net to our interest before any insurance recoveries. Due to the unique nature of the remaining work to be performed, actual costs could greatly exceed these estimates and, depending on the nature of any excess costs incurred, could result in significant charges to earnings in future periods. All of this $33.1 million estimated amount has been accrued as part of Maritech’s decommissioning liabilities. Maritech has additional maximum remaining insurance coverage available of approximately $19.5 million, all of which relates to Hurricane Ike, although a portion of these costs may not be reimbursed. One of the underwriters associated with our windstorm insurance coverage for Hurricane Ike damages has contested whether certain repair costs incurred are covered costs under the policy. During December 2010, we initiated legal proceedings against this underwriter in an attempt to collect the amount of claim reimbursements provided for under the policy. The timing of the collection of any future reimbursements is

31

beyond our control, and we will continue to use a significant amount of our working capital until such reimbursements are received.

Last year’s explosion and subsequent oil spill at the Macondo well evidences the general operating risks associated with offshore oil and gas activities. While we have no liability associated with this specific incident, we are subject to operating hazards normally associated with the oilfield service industry and offshore oil and gas production operations, including fires, explosions, blowouts, cratering, mechanical problems, abnormally pressured formations, and environmental accidents. We maintain various types of business insurance that would be applicable in the event of an explosion or other catastrophic event involving our offshore operations. This insurance includes third-party liability, workers’ compensation and employers’ liability, general liability, vessel pollution liability, and operational risk coverage for our Maritech oil and gas properties, including removal of debris, operator’s extra expense, control of well, and pollution and clean up coverage. Our insurance coverage includes deductibles that must be met prior to recovery. Additionally, our insurance is subject to certain exclusions and limitations. We have elected not to maintain windstorm insurance on Maritech’s remaining offshore oil and gas property assets. We believe our policy of insuring against such risks, as well as the levels of insurance we maintain, is typical in the industry. In addition, we provide services and products in the offshore Gulf of Mexico generally pursuant to agreements that create insurance and indemnity obligations for both parties. Our Maritech subsidiary maintains a formalized oil spill response plan that it submits to BSEE. Maritech has designated employees and third-party contracts in place to ensure that resources are available as required in the event of an environmental accident. While it is impossible to anticipate every potential accident or incident involving our offshore operations, we believe we have taken appropriate steps to mitigate the potential impact of such an event on the environment in the regions in which we operate.

Investing Activities

During the first nine months of 2011, we generated $60.1 million of cash flows from investing activities, reflecting the significant proceeds received from asset sales, primarily from the sales of Maritech properties. During the nine months ended September 30, 2011, we expended $99.9 million of capital expenditures. This capital expenditure activity was spread among each of our operating segments. For certain of our businesses, our capital expenditure plans have been, and will continue to be, reviewed carefully, and a significant amount of planned capital expenditures have been deferred until activity levels increase. This restraint on capital expenditure activity may also affect future growth. The sale of our Maritech assets ended our investing activities on oil and gas exploration and development activities, which was previously a significant portion of our total investing activities. With a portion of the proceeds from the sale of these Maritech assets, in July 2011, we purchased a heavy lift derrick barge with a 1,600-metric-ton lift capacity, fully revolving crane for approximately $62.8 million. Additional costs have been subsequently incurred for inspection, transportation, and outfitting costs on this barge prior to placing it into service, and will result in a total investment in the barge of approximately $71 million. This asset purchase significantly expanded the capability of our Offshore Services segment, and enables us to serve customers with heavier structures in the Gulf of Mexico.

During the first nine months of 2011, our cash capital expenditures totaled approximately $99.9 million. In March 2011, we also expended $1.5 million for the acquisition of a consulting service business associated with our Offshore Services segment. Approximately $13.2 million of capital expenditures during the first nine months of 2011 was expended by our Fluids Division, approximately $3.5 million of which related to the ongoing modification of our calcium chloride plant facility. Our Offshore Division expended approximately $63.2 million, consisting of approximately $55.9 million of expenditures by its Offshore Services segment, primarily for the heavy lift derrick barge discussed above. In addition, the Offshore Division expended $7.3 million of development expenditures for Maritech prior to the sale of substantially all of its oil and gas properties. Our Production Enhancement Division spent approximately $22.5 million, consisting of approximately $13.2 million by the Production Testing segment to replace or enhance a portion of its production testing equipment fleet and approximately $9.3 million by the Compressco segment for general infrastructure needs, along with expansion of its wellhead compressor fleet. Corporate capital expenditures were approximately $0.9 million.

Generally, a significant majority of our planned capital expenditures is related to identified opportunities to grow and expand our existing businesses; however, certain of these expenditures may be postponed or cancelled in our continuing efforts to conserve capital. We plan to expend up to $175 million

32

on total capital expenditures during 2011. This anticipated level of capital expenditure activity would result in increased spending compared to 2010 for each of our business segments other than Maritech and Compressco. The deferral of certain capital projects, such as the additional replacement or upgrading of vessels in our Offshore Services fleet, could affect our ability to compete in the future. Our long-term growth strategy continues to include the pursuit of suitable acquisitions or opportunities to expand operations in oil and gas service markets. To the extent we consummate a significant acquisition transaction, our liquidity position will be affected.

Financing Activities

To fund our capital and working capital requirements, we may supplement our existing cash balances and cash flow from operating activities as needed from long-term borrowings, short-term borrowings, equity issuances, and other sources of capital.

Our Bank Credit Facility

We have a revolving credit facility with a syndicate of banks pursuant to a credit facility agreement that was most recently amended in October 2010 (the Credit Agreement). As of November 9, 2011, we did not have any outstanding balance on the revolving credit facility, although we had $8.1 million in letters of credit and guarantees against the $278 million availability under the revolving credit facility, leaving a net availability of $269.9 million. In addition, the amended credit facility agreement allows us to increase the facility by $150 million up to a $428 million limit upon the agreement of the lenders and the satisfaction of certain conditions.

Under the Credit Agreement, which matures on June 26, 2015, the revolving credit facility is unsecured and guaranteed by certain of our material U.S. subsidiaries (excluding Compressco). Borrowings generally bear interest at the British Bankers Association LIBOR rate plus 1.5% to 2.5%, depending on one of our financial ratios. We pay a commitment fee ranging from 0.225% to 0.500% on unused portions of the facility. The Credit Agreement contains customary covenants and other restrictions, including certain financial ratio covenants involving our levels of debt and interest cost compared to a defined measure of our operating cash flows over a twelve month period. In addition, the Credit Agreement includes limitations on aggregate asset sales, individual acquisitions, and aggregate annual acquisitions and capital expenditures. Access to our revolving credit facility is dependent upon our ability to comply with the financial ratio covenants set forth in the Credit Agreement, as discussed above. Significant deterioration of the financial ratios could result in a default under the Credit Agreement and, if not remedied, could result in termination of the credit agreement and acceleration of any outstanding balances. In June 2011, associated with the contribution of the majority of the operations and related assets and liabilities of our Compressco segment into Compressco Partners, Compressco Partners was designated as an unrestricted subsidiary and is no longer a borrower or a guarantor under our bank credit facility.

The Credit Agreement also includes cross-default provisions relating to any other indebtedness greater than a defined amount. If any such indebtedness is not paid or is accelerated and such event is not remedied in a timely manner, a default will occur under the Credit Agreement. Our Credit Agreement also contains a covenant that restricts us from paying dividends in the event of a default or if such payment would result in an event of default. We are in compliance with all covenants and conditions of our Credit Agreement as of September 30, 2011. Our continuing ability to comply with these financial covenants depends largely upon our ability to generate adequate cash flow. Historically, our financial performance has been more than adequate to meet these covenants, and we expect this trend to continue.

Senior Notes

In April 2006, we issued, and sold through a private placement, $90.0 million in aggregate principal amount of Series 2006-A Senior Notes pursuant to a Master Note Purchase Agreement dated September 2004, as supplemented as of April 18, 2006. The Series 2006-A Senior Notes bear interest at the fixed rate of 5.90% and mature on April 30, 2016. Interest on the 2006-A Senior Notes is due semiannually on April 30 and October 30 of each year.

In April 2008, we issued, and sold through a private placement, $35.0 million in aggregate principal amount of Series 2008-A Senior Notes and $90.0 million in aggregate principal amount of Series 2008-B Senior Notes (collectively the Series 2008 Senior Notes) pursuant to a Note Purchase Agreement dated

33

April 30, 2008. The Series 2008-A Senior Notes bear interest at the fixed rate of 6.30% and mature on April 30, 2013. The Series 2008-B Senior Notes bear interest at the fixed rate of 6.56% and mature on April 30, 2015. Interest on the Series 2008 Senior Notes is due semiannually on April 30 and October 31 of each year.

In December 2010, we issued and sold through a private placement, $65.0 million in aggregate principal amount of Series 2010-A Senior Notes and $25.0 million in aggregate principal amount of Series 2010-B Senior Notes (collectively, the 2010 Senior Notes) pursuant to a Note Purchase Agreement dated September 30, 2010. The Series 2010-A Senior Notes bear interest at the fixed rate of 5.09% and mature on December 15, 2017. The Series 2010-B Senior Notes bear interest at the fixed rate of 5.67% and mature on December 15, 2020. Interest on the Series 2010 Senior Notes is due semiannually on June 15 and December 15 of each year.

Each of the Senior Notes was sold in the United States to accredited investors pursuant to an exemption from the Securities Act of 1933. We may prepay the Senior Notes, in whole or in part, at any time at a price equal to 100% of the principal amount outstanding, plus accrued and unpaid interest and a “make-whole” prepayment premium. The Senior Notes are unsecured and are guaranteed by substantially all of our wholly owned U.S. subsidiaries. The Note Purchase Agreement and the Master Note Purchase Agreement, as supplemented, contain customary covenants and restrictions and require us to maintain certain financial ratios, including a minimum level of net worth and a ratio between our long-term debt balance and a defined measure of operating cash flow over a twelve month period. The Note Purchase Agreements and the Master Note Purchase Agreement also contain customary default provisions as well as a cross-default provision relating to any other of our indebtedness of $20 million or more. We are in compliance with all covenants and conditions of the Note Purchase Agreements and the Master Note Purchase Agreement as of September 30, 2011. Upon the occurrence and during the continuation of an event of default under the Note Purchase Agreements and the Master Note Purchase Agreement, as supplemented, the Senior Notes may become immediately due and payable, either automatically or by declaration of holders of more than 50% in principal amount of the Senior Notes outstanding at the time.

Compressco Partners’ Bank Credit Facility

On June 24, 2011, Compressco Partners entered into a new credit agreement (the Partnership Credit Agreement) with JPMorgan Chase Bank, N.A. Under the Partnership Credit Agreement, Compressco Partners, along with certain of its subsidiaries, are named as borrowers, and all of its existing and future, direct and indirect, domestic subsidiaries are guarantors. We are not a borrower or a guarantor under the Partnership Credit Agreement. The Partnership Credit Agreement includes borrowing capacity of $20.0 million (less $3.0 million that is required to be set aside as a reserve that cannot be borrowed) that is available for letters of credit (with a sublimit of $5.0 million) and an uncommitted $20.0 million expansion feature. The Partnership Credit Agreement may be used to fund Compressco Partners’ working capital needs, letters of credit, and for general partnership purposes, including capital expenditures and potential future acquisitions. So long as Compressco Partners is not in default, the Partnership Credit Agreement could also be used to fund Compressco Partners’ quarterly distributions. Borrowings under the Partnership Credit Agreement are subject to the satisfaction of customary conditions, including the absence of a default. As of September 30, 2011, there is no balance outstanding under the Partnership Credit Agreement. The maturity date of the Partnership Credit Agreement is June 24, 2015.

All obligations under the Partnership Credit Agreement and the guarantees of those obligations are secured, subject to certain exceptions, by a first lien security interest in substantially all of the assets (excluding real property) of Compressco Partners and its existing and future, direct and indirect domestic subsidiaries, and all of the capital stock of its existing and future, direct and indirect subsidiaries (limited, in the case of foreign subsidiaries, to 65% of the capital stock of first tier foreign subsidiaries).

Borrowings under the Partnership Credit Agreement bear interest at a rate per annum equal to, at Compressco Partners’ option, either (a) LIBOR (adjusted to reflect any required bank reserves) for an interest period equal to one, two, three or six months (as we select) plus a margin of 2.25% per annum or (b) a base rate determined by reference to the highest of (1) the prime rate of interest announced from time to time by JPMorgan Chase Bank, N.A. or (2) LIBOR (adjusted to reflect any required bank reserves) for a one-month interest period on such day plus 2.50% per annum. In addition to paying interest on any outstanding principal under the Partnership Credit Agreement, Compressco Partners is required to pay

34

customary collateral monitoring fees and letter of credit fees, including without limitation, a letter of credit fee equal to the applicable margin on revolving credit LIBOR loans and fronting fees.

The Partnership Credit Agreement requires Compressco Partners to maintain a minimum interest coverage ratio (ratio of earnings before interest and taxes to interest) of 2.5 to 1.0 as of the last day of any fiscal quarter, calculated on a trailing four quarter basis, whenever availability is less than $5 million. In addition, the Partnership Credit Agreement includes customary negative covenants, which, among other things, limit Compressco Partners’ ability to incur additional debt, incur or permit certain liens to exist, or make certain loans, investments, acquisitions or other restricted payments. The Partnership Credit Agreement provides that Compressco Partners can make distributions to holders of its common units, but only if there is no default or event of default under the facility. If an event of default occurs, the lenders are entitled to take various actions, including the acceleration of amounts due under the Partnership Credit Agreement and all actions permitted to be taken by secured creditors.

Other Sources

In addition to the revolving credit facility provided by our Credit Agreement, we fund our short-term liquidity requirements from existing cash balances, cash generated by operations, short-term vendor financing and, to a lesser extent, leasing with institutional leasing companies. Should additional capital be required, we believe that we have the ability to raise such capital through the issuance of additional debt or equity. However, instability or volatility in the capital markets at the times we need to access capital may affect the cost of capital and the ability to raise capital. As discussed above, our Credit Agreement and the Partnership Credit Agreement each mature in 2015 and our Senior Notes mature at various dates between April 2013 and December 2020. The replacement of these capital sources at similar or more favorable terms is not certain. If it is necessary to utilize our equity to fund our capital needs, dilution to our common stockholders could occur.

The June 2011 initial public offering by Compressco Partners provides it with the ability to issue additional common units to the public for cash or to use such units as consideration in an acquisition transaction. Additional issuances of Compressco Partners common units would dilute our ownership interest in Compressco Partners.

In November 2009, we filed a universal shelf registration statement on Form S-3 that permits us to issue an indeterminate amount of securities including common stock, preferred stock, senior and subordinated debt securities, warrants, and units. Such securities may be used for working capital needs, capital expenditures, and expenditures related to general corporate purposes, including possible future acquisitions. In May 2004, we filed a universal acquisition shelf registration statement on Form S-4 that permits us to issue up to $400 million of common stock, preferred stock, senior and subordinated debt securities, and warrants in one or more acquisition transactions that we may undertake from time to time.

Off Balance Sheet Arrangements

As of September 30, 2011, we had no “off balance sheet arrangements” that may have a current or future material effect on our consolidated financial condition or results of operations.

Commitments and Contingencies

Litigation

We are named defendants in lawsuits and respondents in governmental proceedings arising in the ordinary course of business. While the outcome of lawsuits or other proceedings against us cannot be predicted with certainty, management does not reasonably expect these matters to have a material adverse impact on the financial statements.

Derivative Lawsuit

Between May 28, 2008 and June 27, 2008, two petitions were filed by alleged stockholders in the District Courts of Harris County, Texas, 133rd and 113th Judicial Districts, purportedly on our behalf. The suits name our directors and certain officers as defendants. The factual allegations in these lawsuits mirror those in a federal class action lawsuit which was settled during 2010. The claims are for breach of fiduciary 

35

duty, unjust enrichment, abuse of control, gross mismanagement, and waste of corporate assets. The petitions seek disgorgement, costs, expenses, and unspecified equitable relief. On September 22, 2008, the 133rd District Court consolidated these complaints as In re TETRA Technologies, Inc. Derivative Litigation, Cause No. 2008-23432 (133rd Dist. Ct., Harris County, Tex.), and appointed Thomas Prow and Mark Patricola as Co-Lead Plaintiffs. This lawsuit was stayed by agreement of the parties pending the Court’s ruling on our motion to dismiss the federal class action. On September 8, 2009, the plaintiffs in this state court action filed a consolidated petition which makes factual allegations similar to the surviving allegations in the federal lawsuit prior to it being settled. On April 19, 2010, the Court granted our motion to abate the suit, based on plaintiff’s inability to demonstrate derivative standing. On June 8, 2010, we received a letter from plaintiff’s counsel demanding that our board of directors take action against the defendants named in the previously filed derivative lawsuit. On August 22, 2011, the Court issued a Preliminary Approval Order preliminarily approving the settlement of the suit as set forth in the Stipulation of Settlement dated August 12, 2011 (the Stipulation). The Stipulation does not provide for the payment of monetary compensation to stockholders; rather, it provides for certain additions to our corporate governance policies and procedures and for the payment of plaintiff’s attorneys’ fees and litigation expenses, which will be paid by our insurers. On October 17, 2011, the Court granted final approval of the settlement.

Environmental

One of our subsidiaries, TETRA Micronutrients, Inc. (TMI), previously owned and operated a production facility located in Fairbury, Nebraska. TMI is subject to an Administrative Order on Consent issued to American Microtrace, Inc. (n/k/a/ TETRA Micronutrients, Inc.) in the proceeding styled In the Matter of American Microtrace Corporation, EPA I.D. No. NED00610550, Respondent, Docket No. VII-98-H-0016, dated September 25, 1998 (the Consent Order), with regard to the Fairbury facility. TMI is liable for future remediation costs and ongoing environmental monitoring at the Fairbury facility under the Consent Order; however, the current owner of the Fairbury facility is responsible for costs associated with the closure of that facility.

Cautionary Statement for Purposes of Forward-Looking Statements

Certain statements contained herein and elsewhere may be deemed to be forward-looking within the meaning of the Private Securities Litigation Reform Act of 1995 and are subject to the “safe harbor” provisions of that act, including, without limitation, statements concerning future or expected sales, earnings, costs, expenses, acquisitions or corporate combinations, including the recent sales of oil and gas properties and the anticipated benefits to be realized from these sales, asset recoveries, expected benefits associated with our purchase of a heavy lift derrick barge, working capital, capital expenditures, financial condition, other results of operations, the expected impact of current economic and capital market conditions on the oil and gas industry and our operations, other statements regarding our beliefs, plans, goals, future events and performance, and other statements that are not purely historical. Such statements involve risks and uncertainties, many of which are beyond our control. Actual results could differ materially from the expectations expressed in such forward-looking statements. Some of the risk factors that could affect our actual results and cause actual results to differ materially from any such results that might be projected, forecast, estimated, or budgeted by us in such forward-looking statements are described in our Annual Report on Form 10-K for the year ended December 31, 2010, and this Quarterly Report on Form 10-Q, and are set forth from time to time in our filings with the Securities and Exchange Commission.

Item 3. Quantitative and Qualitative Disclosures about Market Risk.

In April 2011, in connection with a purchase and sale agreement to sell a significant amount of Maritech’s remaining oil and gas properties, we liquidated the derivative swap financial instruments that were designated as hedges of Maritech’s future oil production. As a result, we are exposed to the commodity price risk associated with Maritech’s oil and natural gas production that we continue to own following the sale. Due to the minimal amount of expected production following the sale, such commodity price risk exposure is not expected to be significant.

36

Item 4. Controls and Procedures.

Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of our disclosure controls and procedures, as such term is defined under Rule 13a-15(e) promulgated under the Securities Exchange Act of 1934, as amended. Based on this evaluation, the Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of September 30, 2011, the end of the period covered by this quarterly report.

There were no changes in our internal control over financial reporting that occurred during the fiscal quarter ended September 30, 2011, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II

OTHER INFORMATION

Item 1. Legal Proceedings.

We are named defendants in lawsuits and respondents in governmental proceedings arising in the ordinary course of business. While the outcome of lawsuits or other proceedings against us cannot be predicted with certainty, management does not reasonably expect these matters to have a material adverse impact on the financial statements.

The information regarding litigation matters described in the Notes to Consolidated Financial Statements, Note H – Commitments and Contingencies, Litigation, and included elsewhere in this Quarterly Report on Form 10-Q is incorporated herein by reference.

Item 1A. Risk Factors.

The terms of the subordinated units we hold in Compressco Partners may result in us not receiving our share of the distributable cash flows of Compressco Partners.

Compressco Partners may not have sufficient cash from operations to enable it to make cash distributions to holders of common units at the minimum quarterly distribution rate under its cash distribution policy. To the extent sufficient distributable cash is not available, the distribution shortfall will first be attributed to the subordinated units we hold, resulting in a reduction in our financing cash flows from distributions from Compressco Partners. Any shortfall in quarterly distributions attributed to the subordinated units will not be carried forward in arrears or recovered in future distributions.

We have elected to self-insure windstorm damage to our Maritech assets in the Gulf of Mexico and hurricane damages could result in significant uninsured losses.

Despite the sale of approximately 95% of Maritech’s yearend oil and gas reserves, we have retained decommissioning liabilities of approximately $125.9 million associated with offshore platforms and associated wells to be decommissioned and abandoned. During the second quarter of 2011, we determined that the cost of premiums and the associated deductibles and coverage limits for windstorm damage for Maritech’s remaining offshore platforms and wells was uneconomical. Therefore, Maritech has discontinued its insurance coverage for windstorm damage for the 2011 hurricane season. Accordingly, Maritech is currently exposed to losses from windstorm damages during the current year and may be similarly exposed to storms in future years if we do not purchase windstorm insurance coverage. Depending on the severity and location of the storms, such losses could be significant and could have a material adverse effect on our financial position, results of operation, and cash flows.

There can be no assurance that future windstorm insurance coverage with more favorable premiums and deductible and maximum coverage amounts will be available in the market or that its cost will be justifiable. There can be no assurance that any windstorm insurance will be adequate to cover losses or liabilities associated with such windstorms. We cannot predict the continued availability of insurance or its availability at premium levels that justify its purchase.

EX-31.1

  Exhibit 31.1

Certification Pursuant to

Rule 13a-14(a) or 15d-14(a) of the Exchange Act

As Adopted Pursuant to

Section 302 of the Sarbanes-Oxley Act of 2002

I, Stuart M. Brightman, certify that:

1.   I have reviewed this report on Form 10-Q for the fiscal quarter ended September 30, 2011, of TETRA Technologies, Inc.;

2.   Based on my knowledge, this report does not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements made, in light of the circumstances under which such statements were made, not misleading with respect to the period covered by this report;

3.   Based on my knowledge, the financial statements, and other financial information included in this report, fairly present in all material respects the financial condition, results of operations and cash flows of the registrant as of, and for, the periods presented in this report;

4.   The registrant’s other certifying officer and I are responsible for establishing and maintaining disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) and internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) for the registrant and have:

a)   designed such disclosure controls and procedures, or caused such disclosure controls and procedures to be designed under our supervision, to ensure that material information relating to the registrant, including its consolidated subsidiaries, is made known to us by others within those entities, particularly during the period in which this report is being prepared;

b)   designed such internal control over financial reporting, or caused such internal control over financial reporting to be designed under our supervision, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles;

Commitments and Contingencies

NOTE H - COMMITMENTS AND CONTINGENCIES

Litigation

We are named defendants in lawsuits and respondents in governmental proceedings arising in the ordinary course of business. While the outcome of lawsuits or other proceedings against us cannot be predicted with certainty, management does not reasonably expect these matters to have a material adverse impact on the financial statements.

Derivative Lawsuit

Between May 28, 2008 and June 27, 2008, two petitions were filed by alleged stockholders in the District Courts of Harris County, Texas, 133rd and 113th Judicial Districts, purportedly on our behalf. The suits name our directors and certain officers as defendants. The factual allegations in these lawsuits mirror those in a federal class action lawsuit which was settled during 2010. The claims are for breach of fiduciary duty, unjust enrichment, abuse of control, gross mismanagement, and waste of corporate assets. The petitions seek disgorgement, costs, expenses, and unspecified equitable relief. On September 22, 2008, the 133rd District Court consolidated these complaints as In re TETRA Technologies, Inc. Derivative Litigation, Cause No. 2008-23432 (133rd Dist. Ct., Harris County, Tex.), and appointed Thomas Prow and Mark Patricola as Co-Lead Plaintiffs. This lawsuit was stayed by agreement of the parties pending the Court's ruling on our motion to dismiss the federal class action. On September 8, 2009, the plaintiffs in this state court action filed a consolidated petition which makes factual allegations similar to the surviving allegations in the federal lawsuit prior to it being settled. On April 19, 2010, the Court granted our motion to abate the suit, based on plaintiff's inability to demonstrate derivative standing. On June 8, 2010, we received a letter from plaintiff's counsel demanding that our board of directors take action against the defendants named in the previously filed derivative lawsuit. On August 22, 2011, the Court issued a Preliminary Approval Order preliminarily approving the settlement of the suit as set forth in the Stipulation of Settlement dated August 12, 2011 (the Stipulation). The Stipulation does not provide for the payment of monetary compensation to stockholders; rather, it provides for certain additions to our corporate governance policies and procedures and for the payment of plaintiff's attorneys' fees and litigation expenses, which will be paid by our insurers. On October 17, 2011, the Court granted final approval of the settlement.

Environmental

One of our subsidiaries, TETRA Micronutrients, Inc. (TMI), previously owned and operated a production facility located in Fairbury, Nebraska. TMI is subject to an Administrative Order on Consent issued to American Microtrace, Inc. (n/k/a/ TETRA Micronutrients, Inc.) in the proceeding styled In the Matter of American Microtrace Corporation, EPA I.D. No. NED00610550, Respondent, Docket No. VII-98-H-0016, dated September 25, 1998 (the Consent Order), with regard to the Fairbury facility. TMI is liable for future remediation costs and ongoing environmental monitoring at the Fairbury facility under the Consent Order; however, the current owner of the Fairbury facility is responsible for costs associated with the closure of that facility.

On June 24, 2011, Compressco Partners entered into a new credit agreement (the Partnership Credit Agreement) with JPMorgan Chase Bank, N.A. Under the Partnership Credit Agreement, Compressco Partners, along with certain of its subsidiaries, are named as borrowers, and all obligations under the credit facility are guaranteed by all of Compressco Partners' existing and future, direct and indirect, domestic subsidiaries. All obligations under the Partnership Credit Agreement are secured, subject to certain exceptions, by a first lien security interest in substantially all  of the assets (excluding real property) of Compressco Partners and its subsidiaries and all of the capital stock of the subsidiaries of Compressco Partners (with some limitations). The Partnership Credit Agreement includes borrowing capacity of $20.0 million, less $3.0 million that is required to be set aside as a reserve that cannot be borrowed. The facility is available for letters of credit (at a sublimit of $5.0 million) and includes an uncommitted $20.0 million expansion feature. The Partnership Credit Agreement will be used to fund Compressco Partners' working capital needs, letters of credit, and for general partnership purposes, including capital expenditures and potential future acquisitions. So long as it is not in default, Compressco Partners may use its credit facility to fund its quarterly distributions. Borrowings under the Partnership Credit Agreement are subject to the satisfaction of customary conditions, including the absence of a default. As of September 30, 2011, there is no balance outstanding under the Partnership Credit Agreement.

Significant Accounting Policies (Policies)

9 Months Ended

Sep. 30, 2011

Basis of Presentation and Significant Accounting Policies

Principles of consolidation policy

The consolidated financial statements include the accounts of our wholly owned subsidiaries. Investments in unconsolidated joint ventures in which we participate are accounted for using the equity method. Our interests in oil and gas properties are proportionately consolidated. All significant intercompany accounts and transactions have been eliminated in consolidation.

The accompanying unaudited consolidated financial statements have been prepared in accordance with Rule 10-01 of Regulation S-X for interim financial statements required to be filed with the Securities and Exchange Commission (SEC) and do not include all information and footnotes required by generally accepted accounting principles for complete financial statements. However, the information furnished reflects all normal recurring adjustments that are, in the opinion of management, necessary to provide a fair statement of the results for the interim periods. The accompanying unaudited consolidated financial statements should be read in conjunction with the audited financial statements for the year ended December 31, 2010.

Reclassifications policy

Certain previously reported financial information has been reclassified to conform to the current year period's presentation. The impact of such reclassifications was not significant to the prior year period's overall presentation.

Cash equivalents policy

Cash Equivalents

We consider all highly liquid cash investments with a maturity of three months or less when purchased to be cash equivalents.

Restricted cash policy

Restricted Cash

Restricted cash is classified as a current asset when it is expected to be repaid or settled in the next twelve month period. Restricted cash reported on our balance sheet as of September 30, 2011, consists primarily of escrowed cash associated with our July 2011 purchase of a new heavy lift derrick barge. The escrowed cash will be included in restricted cash and released to the sellers in accordance with the terms of the escrow agreement.

Inventories policy

Inventories

Inventories are stated at the lower of cost or market value and consist primarily of finished goods. Cost is determined using the weighted average method. Significant components of inventories as of September 30, 2011, and December 31, 2010, are as follows:

	September 30, 2011		December 31, 2010
	(In Thousands)
Finished goods	$	70,433	$	75,874
Raw materials		5,391		5,103
Parts and supplies		21,234		22,457
Work in progress		445		871
Inventories	$	97,503	$	104,305

5

Finished goods inventories include newly manufactured clear brine fluids and recycled brines that are repurchased from certain of our customers. Recycled brines are recorded at cost, using the weighted average method.

Net income per share policy

Net Income per Share

The following is a reconciliation of the weighted average number of common shares outstanding with the number of shares used in the computations of net income per common and common equivalent share:

	Three Months Ended				Nine Months Ended
	September 30,				September 30,
	2011		2010		2011		2010
Number of weighted average common
shares outstanding		76,717,063		75,538,455		76,517,144		75,469,030
Assumed exercise of stock options		1,622,958		1,082,591		1,587,783		1,283,383
Average diluted shares outstanding		78,340,021		76,621,046		78,104,927		76,752,413

In applying the treasury stock method to determine the dilutive effect of the stock options outstanding during the first nine months of 2011, we used the average market price of our common stock of $12.28. For the three months ended September 30, 2011 and 2010, the calculations of the average diluted shares outstanding exclude the impact of 2,054,303 and 2,668,312 outstanding stock options, respectively, that have exercise prices in excess of the average market price, as the inclusion of these shares would have been antidilutive. For the nine months ended September 30, 2011 and 2010, the calculations of the average diluted shares outstanding exclude the impact of 1,874,492 and 2,311,805 outstanding stock options, respectively, that have exercise prices in excess of the average market price, as the inclusion of these shares would have been antidilutive.

Environmental liabilities policy

Environmental Liabilities

Environmental expenditures that result in additions to property and equipment are capitalized, while other environmental expenditures are expensed. Environmental remediation liabilities are recorded on an undiscounted basis when environmental assessments or cleanups are probable and the costs can be reasonably estimated. Estimates of future environmental remediation expenditures often consist of a range of possible expenditure amounts, a portion of which may be in excess of amounts of liabilities recorded. In such an instance, we disclose the full range of amounts reasonably possible of being incurred. Any changes or developments in environmental remediation efforts are accounted for and disclosed each quarter as they occur. Any recoveries of environmental remediation costs from other parties are recorded as assets when their receipt is deemed probable.

Complexities involving environmental remediation efforts can cause the estimates of the associated liability to be imprecise. Factors that cause uncertainties regarding the estimation of future expenditures include, but are not limited to, the effectiveness of the anticipated work plans in achieving targeted results and changes in the desired remediation methods and outcomes as prescribed by regulatory agencies. Uncertainties associated with environmental remediation contingencies are pervasive and often result in wide ranges of reasonably possible outcomes. Estimates developed in the early stages of remediation can vary significantly. Normally, a finite estimate of cost does not become fixed and determinable at a specific point in time. Rather, the costs associated with environmental remediation become estimable as the work is performed and the range of ultimate cost becomes more defined. It is possible that cash flows and results of operations could be materially affected by the impact of the ultimate resolution of these contingencies.

Fair value measurements policy

Fair Value Measurements

Fair value is defined as "the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date" within an entity's principal market, if any. The principal market is the market in which the reporting entity would sell the asset or transfer the liability with the greatest volume and level of activity, regardless of whether it is the market in which the entity will ultimately transact for a particular asset or liability or if a different market is potentially

6

more advantageous. Accordingly, this exit price concept may result in a fair value that may differ from the transaction price or market price of the asset or liability.

Under generally accepted accounting principles, the fair value hierarchy prioritizes inputs to valuation techniques used to measure fair value. Fair value measurements should maximize the use of observable inputs and minimize the use of unobservable inputs, where possible. Observable inputs are developed based on market data obtained from sources independent of the reporting entity. Unobservable inputs may be needed to measure fair value in situations where there is little or no market activity for the asset or liability at the measurement date and are developed based on the best information available in the circumstances, which may include the reporting entity's own judgments about the assumptions market participants would utilize in pricing the asset or liability.

We utilize fair value measurements to account for certain items and account balances within our consolidated financial statements. Fair value measurements are utilized in the allocation of purchase consideration in acquisition transactions to the assets and liabilities acquired, including intangible assets and goodwill. In addition, we utilize fair value measurements in the initial recording of our decommissioning and other asset retirement obligations. Fair value measurements may also be utilized on a nonrecurring basis, such as for the impairment of long-lived assets, including goodwill. The fair value of our financial instruments, which may include cash, temporary investments, accounts receivable, short-term borrowings, and long-term debt pursuant to our bank credit agreement, approximate their carrying amounts. The fair value of our long-term Senior Notes at September 30, 2011, was approximately $334.8 million compared to a carrying amount of approximately $305.0 million, as current rates are more favorable than the Senior Note interest rates. We calculate the fair value of our Senior Notes internally, using current market conditions and average cost of debt. We have not calculated or disclosed recurring fair value measurements of non-financial assets and non-financial liabilities.

During the second quarter of 2011, in connection with the sale of substantially all of our Maritech oil and gas producing properties, we liquidated our derivative contracts and paid $14.2 million to the counterparty. For further discussion see Note F - Hedge Contracts.

During the second quarter of 2011, Maritech recorded impairment charges of approximately $9.2 million associated with its remaining oil and gas properties. During the first nine months of 2011, Maritech sold approximately 95% of its oil and gas reserves as of December 31, 2010, and it is seeking to sell its remaining properties at current market values. Accordingly, all of Maritech's remaining oil and gas properties as of September 30, 2011, have been reclassified to oil and gas properties held for sale and their net book values have been adjusted to fair value less cost to sell. Fair values are estimated based on current market prices being received for these properties' expected future production cash flows, using forward oil and natural gas pricing data from published sources. Because such published forward pricing data was applied to estimated oil and gas reserve volumes based on our internally prepared reserve estimates, such fair value calculation is based on significant unobservable inputs (Level 3) in accordance with the fair value hierarchy.

A summary of the nonrecurring fair value measurements discussed above as of September 30, 2011 and 2010, using the fair value hierarchy is as follows:

New accounting pronouncements policy

New Accounting Pronouncements

In September 2011, the Financial Accounting Standards Board (FASB) published Accounting Standards Update (ASU) 2011-08, "Intangibles - Goodwill and Other (Topic 350), Testing Goodwill for Impairment" (ASU 2011-08), which simplifies how entities test goodwill for impairment. The amendments in ASU 2011-08 permit an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test described in Topic 350. The ASU is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. Early adoption is permitted. The adoption of ASU 2011-08 is not expected to have a significant impact on our financial statements.

In June 2011, the FASB published ASU 2011-05, "Comprehensive Income (Topic 220), Presentation of Comprehensive Income" (ASU 2011-05), which has the objective of improving the comparability, consistency, and transparency of financial reporting and increasing the prominence of items reported in other comprehensive income. As part of ASU 2011-05, the FASB decided to eliminate the option to present components of other comprehensive income as part of the statement of changes in stockholders' equity, among other amendments in this ASU. The amendments require that all non-owner changes in stockholders' equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The amendments in this ASU are to be effective for fiscal years, and interim periods within those years, beginning after December 15, 2011, and the amendments are to be applied retrospectively. In October 2011, the FASB announced that it will consider deferring certain aspects of ASU 2011-05. The adoption of the accounting and disclosure requirements of this ASU is not expected to have a significant impact on our financial statements.

In May 2011, the FASB published ASU 2011-04, "Fair Value Measurement (Topic 820) - Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs," whereby the FASB and the International Accounting Standards Board (IASB) aligned their definitions of fair value such that their fair value measurement and disclosure requirements are the same (except for minor differences in wording and style). The Boards concluded that the amendments in this ASU will improve the comparability of fair value measurements presented and disclosed in financial statements prepared in accordance with U.S. GAAP and IFRS. The amendments in this ASU are effective during interim and annual periods beginning after December 15, 2011, and are to be applied prospectively. The adoption of the accounting and disclosure requirements of this ASU will not have a significant impact on our financial statements.

Notes to Financial Statements [Abstract]

Segment Reporting

NOTE I - INDUSTRY SEGMENTS

We manage our operations through five operating segments: Fluids, Offshore Services, Maritech, Production Testing, and Compressco.

Our Fluids Division manufactures and markets clear brine fluids, additives, and other associated products and services to the oil and gas industry for use in well drilling, completion, and workover operations in the United States and in certain countries in Latin America, Europe, Asia, the Middle East, and Africa. The Division also markets liquid and dry calcium chloride products manufactured at its production facilities to a variety of markets outside the energy industry.

Our Offshore Division consists of two operating segments: Offshore Services and Maritech, an oil and gas exploration, exploitation, and production segment. The Offshore Services segment provides (1) downhole and subsea oil and gas services such as well plugging and abandonment, workover, and wireline services, (2) decommissioning and certain construction services utilizing heavy lift barges and various

14

cutting technologies with regard to offshore oil and gas production platforms and pipelines, and (3) conventional and saturated air diving services.

The Maritech segment consists of our Maritech subsidiary, which is an oil and gas exploration, development, and production operation focused in the offshore and onshore U.S. Gulf Coast region. As a result of certain sales transactions during the first nine months of 2011, including the May 31, 2011, sale of a significant portion of Maritech's oil and gas properties, Maritech has sold approximately 95% of its proved reserves as of December 31, 2010. Maritech's remaining operations consist primarily of the ongoing abandonment and decommissioning associated with its remaining offshore facilities and production platforms. Maritech intends to acquire a significant portion of these services from the Offshore Division's Offshore Services segment.

Our Production Enhancement Division consists of two operating segments: Production Testing and Compressco. The Production Testing segment provides production testing services in many of the major oil and gas basins in the United States, as well as certain onshore basins in certain regions in Mexico, Brazil, Northern Africa, the Middle East, and other international markets.

The Compressco segment provides wellhead compression-based and other production enhancement services throughout many of the onshore producing regions of the United States, as well as certain onshore basins in Canada, Mexico, South America, Europe, Asia, and other international locations. Beginning June 20, 2011, following Compressco Partners' initial public offering, we allocate and charge certain corporate and divisional direct and indirect administrative costs to Compressco Partners.

We generally evaluate performance and allocate resources of our segments based on profit or loss from operations before income taxes and nonrecurring charges, return on investment, and other criteria. Transfers between segments and geographic areas are priced at the estimated fair value of the products or services as negotiated between the operating units. "Corporate overhead" includes corporate general and administrative expenses, corporate depreciation and amortization, interest income and expense, and other income and expense.

Summarized financial information concerning the business segments from continuing operations is as follows:

Acquisitions and Dispositions

NOTE B - ACQUISITIONS AND DISPOSITIONS

In March 2011, we acquired a project management and engineering consulting services business that provides liability and risk assessment services for domestic and international offshore well abandonment and decommissioning projects. The purchase price for this acquisition was $1.5 million and the assets acquired consist primarily of intangible assets.

In late 2010, we began to decrease our investment in Maritech by suspending oil and gas property acquisitions, decreasing our development activities, exploring strategic alternatives to our ownership of Maritech and its oil and gas properties, and reviewing opportunities to sell Maritech oil and gas property packages. As part of this overall effort, in February and March 2011, Maritech sold certain properties, along with the associated decommissioning liabilities. As part of these transactions, Maritech paid an aggregate of

8

approximately $2.8 million after normal purchase price adjustments. These sold properties, in the aggregate, accounted for approximately 12% of Maritech's proved reserves as of December 31, 2010.

On May 31, 2011, Maritech completed the sale of approximately 79% of its proved oil and gas reserves as of December 31, 2010, to Tana Exploration Company LLC (Tana), a subsidiary of TRT Holdings, Inc. (TRT), pursuant to a Purchase and Sale Agreement dated April 1, 2011. The sale was made to Tana for a base purchase price of $222.3 million. At the closing of the sale, Tana assumed approximately $72.7 million of associated asset retirement obligations, and Maritech received $173.3 million cash, representing the base purchase price less $11.1 million that consisted of a deposit that was paid in April 2011 and purchase price adjustments, including those adjustments reflecting cash flows subsequent to the January 1, 2011, effective date. The proceeds are subject to additional post-closing adjustments. As a result of the sale, we recorded a consolidated gain on sale of assets of $58.1 million. Due to Maritech's continuing efforts to sell its remaining oil and gas properties, such properties have been reclassified to oil and gas properties held for sale, and their net book values have been adjusted to fair value. In connection with the sale of Maritech oil and gas producing properties, during the second quarter of 2011, we charged to general and administrative expenses approximately $2.7 million of employee retention and incentive benefits paid in connection with these sales.

In August 2011, Maritech sold an additional remaining oil and gas property in exchange for the purchaser assuming the associated decommissioning liability. The sold property represents approximately 3% of Maritech's December 31, 2010 oil and gas reserves.

On July 20, 2011, we purchased a new heavy lift derrick barge (which we have named the TETRA Hedron) with a 1,600-metric-ton lift capacity, fully revolving crane. The vessel was purchased from Wison (Nantong) Heavy Industry Co., Ltd. and Nantong MLC Tongbao Shipbuilding Co., Ltd. for $62.8 million. Approximately $20.8 million of the purchase price is held in certain escrow accounts and will be released in accordance with the terms of the escrow agreements. The amount of remaining cash in escrow will be included in restricted cash on our consolidated balance sheet until the final release of escrow cash on April 30, 2014. The vessel was transported to the Gulf of Mexico during the third quarter and will be placed into service during the fourth quarter of 2011 following final outfitting and sea trials.

Asset Retirement Obligations

NOTE E - DECOMMISSIONING AND OTHER ASSET RETIREMENT OBLIGATIONS

The large majority of our asset retirement obligations consists of the future well abandonment and decommissioning costs for offshore oil and gas facilities and platforms owned by our Maritech subsidiary, including the remaining abandonment, decommissioning, and debris removal costs associated with offshore platforms destroyed by hurricanes. The amount of decommissioning liabilities recorded by Maritech is reduced by amounts allocable to joint interest owners, anticipated insurance recoveries, and any contractual amount to be paid by the previous owner of the oil and gas property when the liabilities are satisfied.

The changes in the asset retirement obligations during the three month and nine month periods ended September 30, 2011 and 2010 are as follows:

	Three Months Ended September 30,
	2011			2010
	(In Thousands)
Beginning balance as of June 30	$	144,525		$	216,147

	Nine Months Ended September 30,

Beginning balance as of December 31 of
the preceding year	$	272,815		$	224,110

Retirement obligations incurred		-			-

Settlement of retirement obligations		(183,129	)		(68,046	)
Ending balance as of September 30	$	133,595		$	202,235

10

Revisions in estimated cash flows for the three months and nine months ended September 30, 2011, are primarily related to the retained Maritech facilities and platforms. Settlements of asset retirement obligations during the three months and nine months ended September 30, 2011, include approximately $3.3 million and $122.0 million, respectively, of obligations associated with oil and gas properties that were sold by Maritech during the periods.

Hedging Activities

Notes to Financial Statements [Abstract]

Hedging Activities

NOTE F - HEDGE CONTRACTS

We are exposed to financial and market risks that affect our businesses. We have currency exchange rate risk exposure related to transactions denominated in a foreign currency as well as to investments in certain of our international operations. As a result of our variable rate bank credit facilities including the variable rate credit facility of Compressco Partners, to the extent we have debt outstanding, we face market risk exposure related to changes in applicable interest rates. We have concentrations of credit risk as a result of trade receivables owed to us by companies in the energy industry. In addition, we have market risk exposure in the sales prices we receive for the remainder of our oil and gas production. Our financial risk management activities may involve, among other measures, the use of derivative financial instruments, such as swap and collar agreements, to hedge the impact of market price risk exposures. Prior to the execution of the purchase and sale agreement in April 2011 pursuant to which we sold substantially all of our remaining Maritech oil and gas properties in May 2011, we utilized cash flow commodity hedge transactions to reduce our exposure related to the volatility of oil and gas prices. For these and other hedge contracts, we formally document all relationships between hedging instruments and hedged items, as well as our risk management objectives, our strategies for undertaking various hedge transactions, and our methods for assessing and testing correlation and hedge ineffectiveness. All hedging instruments are linked to the hedged asset, liability, firm commitment, or forecasted transaction. We also assess, both at the inception of the hedge and on an ongoing basis, whether the derivatives that are used in these hedging transactions are highly effective in offsetting changes in cash flows of the hedged items. As indicated below, these cash flow commodity hedge contracts were liquidated in the second quarter of 2011.

Derivative Hedge Contracts

In April 2011, following the execution of the purchase and sale agreement pursuant to which Maritech agreed to sell approximately 79% of its proved reserves as of December 31, 2010, we liquidated our remaining oil hedge contracts and paid $14.2 million to the counterparty. Therefore, during the three months ended September 30, 2011, we had no remaining cash flow hedging swap contracts outstanding associated with our Maritech subsidiary's oil or gas production.

Notes to Financial Statements [Abstract]

Summary of Significant Accounting Policies

NOTE A - BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES

We are a geographically diversified oil and gas services company focused on completion fluids and services, production testing, wellhead compression, and selected offshore services including well plugging and abandonment, decommissioning, and diving. We were incorporated in Delaware in 1981. We are composed of five reporting segments organized into three divisions - Fluids, Offshore, and Production Enhancement. Included in our Offshore Division is our Maritech segment, an oil and gas exploration and production business that sold approximately 95% of its proved oil and gas reserves in the first eight months of 2011, and whose continuing operations consist primarily of the ongoing well plugging, abandonment, and decommissioning of its remaining offshore production platforms. Unless the context requires otherwise, when we refer to "we," "us," and "our," we are describing TETRA Technologies, Inc. and its consolidated subsidiaries on a consolidated basis.

The consolidated financial statements include the accounts of our wholly owned subsidiaries. Investments in unconsolidated joint ventures in which we participate are accounted for using the equity method. Our interests in oil and gas properties are proportionately consolidated. All significant intercompany accounts and transactions have been eliminated in consolidation.

The accompanying unaudited consolidated financial statements have been prepared in accordance with Rule 10-01 of Regulation S-X for interim financial statements required to be filed with the Securities and Exchange Commission (SEC) and do not include all information and footnotes required by generally accepted accounting principles for complete financial statements. However, the information furnished reflects all normal recurring adjustments that are, in the opinion of management, necessary to provide a fair statement of the results for the interim periods. The accompanying unaudited consolidated financial statements should be read in conjunction with the audited financial statements for the year ended December 31, 2010.

Certain previously reported financial information has been reclassified to conform to the current year period's presentation. The impact of such reclassifications was not significant to the prior year period's overall presentation.

Cash Equivalents

We consider all highly liquid cash investments with a maturity of three months or less when purchased to be cash equivalents.

Restricted Cash

Restricted cash is classified as a current asset when it is expected to be repaid or settled in the next twelve month period. Restricted cash reported on our balance sheet as of September 30, 2011, consists primarily of escrowed cash associated with our July 2011 purchase of a new heavy lift derrick barge. The escrowed cash will be included in restricted cash and released to the sellers in accordance with the terms of the escrow agreement.

Inventories

Inventories are stated at the lower of cost or market value and consist primarily of finished goods. Cost is determined using the weighted average method. Significant components of inventories as of September 30, 2011, and December 31, 2010, are as follows:

	September 30, 2011		December 31, 2010
	(In Thousands)
Finished goods	$	70,433	$	75,874
Raw materials		5,391		5,103
Parts and supplies		21,234		22,457
Work in progress		445		871
Inventories	$	97,503	$	104,305

5

Finished goods inventories include newly manufactured clear brine fluids and recycled brines that are repurchased from certain of our customers. Recycled brines are recorded at cost, using the weighted average method.

Net Income per Share

The following is a reconciliation of the weighted average number of common shares outstanding with the number of shares used in the computations of net income per common and common equivalent share:

	Three Months Ended				Nine Months Ended
	September 30,				September 30,
	2011		2010		2011		2010
Number of weighted average common
shares outstanding		76,717,063		75,538,455		76,517,144		75,469,030
Assumed exercise of stock options		1,622,958		1,082,591		1,587,783		1,283,383
Average diluted shares outstanding		78,340,021		76,621,046		78,104,927		76,752,413

In applying the treasury stock method to determine the dilutive effect of the stock options outstanding during the first nine months of 2011, we used the average market price of our common stock of $12.28. For the three months ended September 30, 2011 and 2010, the calculations of the average diluted shares outstanding exclude the impact of 2,054,303 and 2,668,312 outstanding stock options, respectively, that have exercise prices in excess of the average market price, as the inclusion of these shares would have been antidilutive. For the nine months ended September 30, 2011 and 2010, the calculations of the average diluted shares outstanding exclude the impact of 1,874,492 and 2,311,805 outstanding stock options, respectively, that have exercise prices in excess of the average market price, as the inclusion of these shares would have been antidilutive.

Environmental Liabilities

Environmental expenditures that result in additions to property and equipment are capitalized, while other environmental expenditures are expensed. Environmental remediation liabilities are recorded on an undiscounted basis when environmental assessments or cleanups are probable and the costs can be reasonably estimated. Estimates of future environmental remediation expenditures often consist of a range of possible expenditure amounts, a portion of which may be in excess of amounts of liabilities recorded. In such an instance, we disclose the full range of amounts reasonably possible of being incurred. Any changes or developments in environmental remediation efforts are accounted for and disclosed each quarter as they occur. Any recoveries of environmental remediation costs from other parties are recorded as assets when their receipt is deemed probable.

Complexities involving environmental remediation efforts can cause the estimates of the associated liability to be imprecise. Factors that cause uncertainties regarding the estimation of future expenditures include, but are not limited to, the effectiveness of the anticipated work plans in achieving targeted results and changes in the desired remediation methods and outcomes as prescribed by regulatory agencies. Uncertainties associated with environmental remediation contingencies are pervasive and often result in wide ranges of reasonably possible outcomes. Estimates developed in the early stages of remediation can vary significantly. Normally, a finite estimate of cost does not become fixed and determinable at a specific point in time. Rather, the costs associated with environmental remediation become estimable as the work is performed and the range of ultimate cost becomes more defined. It is possible that cash flows and results of operations could be materially affected by the impact of the ultimate resolution of these contingencies.

Fair Value Measurements

Fair value is defined as "the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date" within an entity's principal market, if any. The principal market is the market in which the reporting entity would sell the asset or transfer the liability with the greatest volume and level of activity, regardless of whether it is the market in which the entity will ultimately transact for a particular asset or liability or if a different market is potentially

6

more advantageous. Accordingly, this exit price concept may result in a fair value that may differ from the transaction price or market price of the asset or liability.

Under generally accepted accounting principles, the fair value hierarchy prioritizes inputs to valuation techniques used to measure fair value. Fair value measurements should maximize the use of observable inputs and minimize the use of unobservable inputs, where possible. Observable inputs are developed based on market data obtained from sources independent of the reporting entity. Unobservable inputs may be needed to measure fair value in situations where there is little or no market activity for the asset or liability at the measurement date and are developed based on the best information available in the circumstances, which may include the reporting entity's own judgments about the assumptions market participants would utilize in pricing the asset or liability.

We utilize fair value measurements to account for certain items and account balances within our consolidated financial statements. Fair value measurements are utilized in the allocation of purchase consideration in acquisition transactions to the assets and liabilities acquired, including intangible assets and goodwill. In addition, we utilize fair value measurements in the initial recording of our decommissioning and other asset retirement obligations. Fair value measurements may also be utilized on a nonrecurring basis, such as for the impairment of long-lived assets, including goodwill. The fair value of our financial instruments, which may include cash, temporary investments, accounts receivable, short-term borrowings, and long-term debt pursuant to our bank credit agreement, approximate their carrying amounts. The fair value of our long-term Senior Notes at September 30, 2011, was approximately $334.8 million compared to a carrying amount of approximately $305.0 million, as current rates are more favorable than the Senior Note interest rates. We calculate the fair value of our Senior Notes internally, using current market conditions and average cost of debt. We have not calculated or disclosed recurring fair value measurements of non-financial assets and non-financial liabilities.

During the second quarter of 2011, in connection with the sale of substantially all of our Maritech oil and gas producing properties, we liquidated our derivative contracts and paid $14.2 million to the counterparty. For further discussion see Note F - Hedge Contracts.

During the second quarter of 2011, Maritech recorded impairment charges of approximately $9.2 million associated with its remaining oil and gas properties. During the first nine months of 2011, Maritech sold approximately 95% of its oil and gas reserves as of December 31, 2010, and it is seeking to sell its remaining properties at current market values. Accordingly, all of Maritech's remaining oil and gas properties as of September 30, 2011, have been reclassified to oil and gas properties held for sale and their net book values have been adjusted to fair value less cost to sell. Fair values are estimated based on current market prices being received for these properties' expected future production cash flows, using forward oil and natural gas pricing data from published sources. Because such published forward pricing data was applied to estimated oil and gas reserve volumes based on our internally prepared reserve estimates, such fair value calculation is based on significant unobservable inputs (Level 3) in accordance with the fair value hierarchy.

A summary of the nonrecurring fair value measurements discussed above as of September 30, 2011 and 2010, using the fair value hierarchy is as follows:

New Accounting Pronouncements

In September 2011, the Financial Accounting Standards Board (FASB) published Accounting Standards Update (ASU) 2011-08, "Intangibles - Goodwill and Other (Topic 350), Testing Goodwill for Impairment" (ASU 2011-08), which simplifies how entities test goodwill for impairment. The amendments in ASU 2011-08 permit an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test described in Topic 350. The ASU is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. Early adoption is permitted. The adoption of ASU 2011-08 is not expected to have a significant impact on our financial statements.

In June 2011, the FASB published ASU 2011-05, "Comprehensive Income (Topic 220), Presentation of Comprehensive Income" (ASU 2011-05), which has the objective of improving the comparability, consistency, and transparency of financial reporting and increasing the prominence of items reported in other comprehensive income. As part of ASU 2011-05, the FASB decided to eliminate the option to present components of other comprehensive income as part of the statement of changes in stockholders' equity, among other amendments in this ASU. The amendments require that all non-owner changes in stockholders' equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The amendments in this ASU are to be effective for fiscal years, and interim periods within those years, beginning after December 15, 2011, and the amendments are to be applied retrospectively. In October 2011, the FASB announced that it will consider deferring certain aspects of ASU 2011-05. The adoption of the accounting and disclosure requirements of this ASU is not expected to have a significant impact on our financial statements.

In May 2011, the FASB published ASU 2011-04, "Fair Value Measurement (Topic 820) - Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs," whereby the FASB and the International Accounting Standards Board (IASB) aligned their definitions of fair value such that their fair value measurement and disclosure requirements are the same (except for minor differences in wording and style). The Boards concluded that the amendments in this ASU will improve the comparability of fair value measurements presented and disclosed in financial statements prepared in accordance with U.S. GAAP and IFRS. The amendments in this ASU are effective during interim and annual periods beginning after December 15, 2011, and are to be applied prospectively. The adoption of the accounting and disclosure requirements of this ASU will not have a significant impact on our financial statements.

Notes to Financial Statements [Abstract]

Compressco Partners, L.P. Initial Public Offering

NOTE C - COMPRESSCO PARTNERS, L.P. INITIAL PUBLIC OFFERING

On June 20, 2011, our Compressco Partners, L.P. (Compressco Partners) subsidiary completed its initial public offering of 2,670,000 common units (representing a 17.3% limited partner interest) in exchange for $53.4 million of gross proceeds (the Offering). Following the issuance of an additional 400,500 units to us in July 2011 as a result of the expiration of an underwriters' option to purchase additional common units, our ownership in Compressco Partners has been increased to 83.2%, including common units, subordinated units, and a 2% general partner interest. In connection with the Offering, certain of our wholly owned subsidiaries, including Compressco Partners GP Inc. (the General Partner), contributed substantially all of our Compressco segment's wellhead compression-based production enhancement service business, operations, and related assets and liabilities to Compressco Partners and its wholly owned subsidiaries. In exchange, including the additional units issued in July 2011, Compressco Partners issued to us 6,427,257 common units (representing a 40.6% limited partner interest), 6,273,970 subordinated units (representing a 39.6% limited partner interests), an aggregate 2.0% general partner interest, and incentive distribution rights. Also, certain directors, executive officers, and other employees of the General Partner were then issued 157,870 restricted units (representing a 1.0% limited partner interest) granted pursuant to a long-term incentive plan. The issuance of the 2,670,000 common units in the Offering, at a $20 per unit Offering Price, resulted in Compressco Partners receiving $53.4 million of gross proceeds, $32.2 million of which was distributed to us to repay an intercompany loan balance. Approximately $11.1 million of the Offering proceeds was or will be used to satisfy Offering expenses, including underwriters' discount and approximately $7.3 million that was paid to us by Compressco Partners to reimburse us for costs we incurred on their behalf. The contribution transactions described above represent transactions between entities under common control. Consequently, the contributed assets were recorded at our carrying value.

The contributions of the majority of the operations and related assets and liabilities of our Compressco segment were effected pursuant to the terms of a Contribution, Conveyance and Assumption Agreement (the Contribution Agreement). Compressco Partners is governed by the First Amended and

9

Restated Agreement of Limited Partnership (the Partnership Agreement). The Partnership Agreement requires Compressco Partners to distribute all of its available cash, as defined in the Partnership Agreement, to the holders of the common units, subordinated units, 2% general partner interest, and incentive distribution rights in accordance with the terms of the Partnership Agreement. The Partnership Agreement also provides for the management of Compressco Partners by the General Partner. The reimbursement of direct and indirect costs incurred by us in providing personnel and services on behalf of Compressco Partners, as well as other transactions between us and Compressco Partners, is governed by the terms of an Omnibus Agreement between us and Compressco Partners.

Following the Offering, as of September 30, 2011, the 16.8% portion of Compressco Partners owned by public unitholders is reflected as a noncontrolling interest in our consolidated financial statements.
