NOTE A – BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES

We are a geographically diversified oil and gas services company, focused on completion fluids and associated products and services, frac water management, after-frac flow back, production well testing, offshore rig cooling, compression-based production enhancement, and selected offshore services including well plugging and abandonment, decommissioning, and diving. We also have a limited domestic oil and gas production business. We were incorporated in Delaware in 1981 and are composed of five reporting segments organized into three divisions – Fluids, Production Enhancement, and Offshore. 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, which 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, 2012.

Beginning with the three month period ended September 30, 2013, certain ad valorem tax expenses for operating equipment of our Compressco segment have been classified as cost of revenues instead of being included in general and administrative expense as reported in prior periods. Prior period amounts have been reclassified to conform to the current year period's presentation. The amount of such reclassification is $0.7 million for the six month period ended June 30, 2013, and $0.4 million and $1.2 million for the three and nine month periods ended September 30, 2012, respectively. This reclassification had no effect on net income for any of the periods presented.

Certain other 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, 2013, consists primarily of escrowed cash associated with our July 2011 purchase of a heavy lift derrick barge. The escrowed cash will be released to the sellers or us 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, 2013, and December 31, 2012, are as follows: 

6

	September 30, 2013		December 31, 2012
	(In Thousands)
Finished goods	$	64,756	$	72,312
Raw materials	4,269		5,396
Parts and supplies	22,576		24,497
Work in progress	724		836
Total inventories	$	92,325	$	103,041

Finished goods inventories include newly manufactured clear brine fluids as well as recycled brines that are repurchased from certain 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   September 30,		Nine Months Ended   September 30,
	2013	2012	2013	2012
	(In Thousands)
Number of weighted average common shares outstanding	78,030	77,329	77,867	77,226
Assumed exercise of stock awards	933	1,609	852	1,514
Average diluted shares outstanding	78,963	78,938	78,719	78,740

In applying the treasury stock method to determine the dilutive effect of the stock options outstanding during the first nine months of 2013, we used the average market price of our common stock of $10.07. For thethree and nine months ended September 30, 2013, the average diluted shares outstanding excludes the impact of 1,571,777 and2,241,490outstanding 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 three and nine months ended September 30, 2012, the average diluted shares outstanding excludes the impact of 2,144,779and 2,054,303outstanding 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 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.

Repair Costs and Insurance Recoveries

During December 2010,we initiated legal proceedings against one of Maritech’sinsuranceunderwriters thathaddisputedthat certainhurricane damage relatedcosts incurred or to be incurred qualifiedas covered costs pursuant toMaritech’s windstorminsurancepolicies. In February 2013, we entered into a settlement agreement with the underwriter whereby we received $7.6 million, a portion of which was credited to operating expenses during the nine months ended September 30, 2013.

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 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 could 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 for 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 values of our long-term Senior Notes at September 30, 2013, and December 31, 2012, were approximately $323.2 million and $327.4 million, respectively, compared to a carrying amount of $305.0 million, as current rates onthose dates were more favorable than the stated interest rates on the Senior Notes. We calculate the fair value of our Senior Notes internally, using current market conditions and average cost of debt (a level 2 fair value measurement). The fair values of the liability for the OPTIMA contingent purchase price consideration at September 30, 2013, and December 31, 2012, were approximately $0.6 million and $2.7 million, respectively. We calculate the fair value of the liability for our contingent purchase price consideration obligation in accordance with the OPTIMA share purchase agreement based upon the actual and anticipated earnings of our OPTIMA operations (a level 3 fair value measurement).

New Accounting Pronouncements

In June 2011, theFinancial Accounting Standards Board (FASB) published Accounting Standards Update (ASU) 2011-05, “Comprehensive Income (Topic 220), Presentation of Comprehensive Income” (ASU 2011-05), with the stated 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 eliminated the option to present components of other comprehensive income as part of the statement of changes in stockholders’ equity. The ASU2011-05amendments 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 ASU2011-05amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2011, and the amendments are applied retrospectively. In December 2011, with the issuance of ASU 2011-12, “Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05,” the FASB announced that it has deferred certain aspects of ASU 2011-05. In February 2013, the FASB issued ASU 2013-2, “Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income,” with the stated objective of improving the reporting of reclassifications out of accumulated other comprehensive income. The amendments in ASU2013-2are effective during interim and annual periods beginning after December 31,2012. The adoption of

8

ASU 2011-05, 2011-12 and 2013-2regarding comprehensive income have not had a significant impact on the accounting or disclosures in our financial statements. 

In December 2011, the FASB published ASU 2011-11, “Balance Sheet (Topic 210), Disclosures about Offsetting Assets and Liabilities” (ASU 2011-11), which requires an entity to disclose the nature of its rights of setoff and related arrangements associated with its financial instruments and derivative instruments. The objective of ASU 2011-11 is to make financial statements that are prepared under U.S. generally accepted accounting principles more comparable to those prepared under International Financial Reporting Standards. The new disclosures will give financial statement users information about both gross and net exposures. In January 2013, the FASB published ASU 2013-01, “Balance Sheet (Topic 210), Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities” (ASU 2013-01), with the stated objective of clarifying the scope of offsetting disclosures and address any unintended consequences of ASU 2011-11. ASU 2011-11 and ASU 2013-01 are effective for interim and annual reporting periods beginning after January 1, 2013, and will be applied on a retrospective basis. The adoption ofASU 2011-11 and ASU 2013-01 did nothave a material impact on our financial condition, results of operations, or liquidity.

In July 2013, the FASB published ASU No. 2013-11,"Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists" (ASU 2013-11). The amendments in this ASU provide guidance on presentation of unrecognized tax benefits and are expected to reduce diversity in practice and better reflect the manner in which an entity would settle at the reporting date any additional income taxes that would result from the disallowance of a tax position when net operating loss carryforwards, similar tax losses, or tax credit carryforwards exist. The amendments in this ASU are effective prospectively for interim and annual periods beginning after December 15, 2013, with early adoption and retrospective application permitted. We do not expect the adoption of this standard to have a material impact on our consolidated financial statements.

NOTE B – ACQUISITIONS AND DISPOSITIONS

Acquisition of Joint Venture Interest

In October 2013, we entered into an agreement to acquire the remaining 50% ownership interest of Ahmad Albinali & TETRA Arabia Company Ltd., a Saudi Arabian limited liability company. The closing of the transaction, which is subject to customary approvals by Saudi Arabian governmental agencies as well as other conditions, is expected to occur during the fourth quarter of 2013 or early 2014. Following the closing of this transaction, the Saudi Arabian limited liability company will become a wholly owned consolidated subsidiary.

Acquisition of Optima

On March 9, 2012, we acquired 100% of the outstanding common stock of Optima Solutions Holdings Limited (OPTIMA), a provider of rig cooling services and associated products that suppress heat generated by high- rate flaring of hydrocarbons during offshore well test operations. The acquisition of OPTIMA, which is based in Aberdeen, Scotland, enables our Production Testing segment to provide its customers with a broader range of production testing and associated services and expands the segment’s presence in many significant global markets. Including the impact of additional working capital received and other adjustments to the purchase price, we paid 41.2 million pounds sterling (approximately $65.0 million equivalent) in cash as the purchase price for the OPTIMA stock at closing and may pay up to an additional 4 million pounds sterling in contingent consideration, depending on a defined measure of earnings for OPTIMA over each of the two years subsequent to the closing.

We allocated the purchase price to the fair value of the assets and liabilities acquired, which consisted of approximately $3.0 million of net working capital; $16.8 million of property, plant, and equipment; $20.4 million of certain intangible assets; $7.2 million of deferred and other tax liabilities; $3.5 million of other liabilities associated with the contingent consideration; and $35.6 million of nondeductible goodwill. The fair value of the obligation to pay the contingent consideration was calculated based on the anticipated earnings for OPTIMA over each of the next two twelve month periods subsequent to the closing and could increase (up to 4 million pounds sterling) or decrease (to zero) depending on OPTIMA’s actual and expected earnings going forward. Increases or decreases in the value of the anticipated contingent consideration liability due to changes in the amounts paid or expected to be paid will be charged or credited to earnings in the period in which such changes occur. Subsequent to the acquisition, the liability associated with the contingent consideration was adjusted downward by approximately $1.8 million (approximately $0.7 million of which was adjusted during the nine months ended September 30, 2013), and

9

this amount was credited to earnings. The $35.6 million of goodwill recorded to our Production Testing segment as a result of the OPTIMA acquisition is supported by the expected strategic benefits discussed above to be generated from the acquisition. For the nine month period ended September 30, 2012, our revenues, depreciation and amortization, and pretax earnings included $15.1 million, $3.1 million, and $3.6 million, respectively, associated with the acquired operations of OPTIMA after the closing in March 2012. Transaction costs associated with the acquisition of approximately $1.3 million were also charged to general and administrative expense during the nine month period ended September 30, 2012.

Acquisition of ERS

On April 23, 2012, we acquired the assets and operations of Eastern Reservoir Services (ERS), a division of Patterson-UTI Energy, Inc., for a cash purchase price of $42.5 million. ERS is a provider of production testing and after-frac flow back services to oil and gas operators in the Appalachian and U.S. Rocky Mountain regions, and the acquisition represented a strategic geographic expansion of our Production Testing segment operations, allowing it to serve customers in additional basins in the U.S.

We allocated the purchase price to the fair value of the assets acquired, which consisted of approximately $18.5 million of property, plant, and equipment, approximately $3.4 million of certain intangible assets, and approximately $20.6 million of nondeductible goodwill. The $20.6 million of goodwill recorded to our Production Testing segment as a result of the ERS acquisition is supported by the strategic benefits discussed above to be generated from the acquisition. For the nine month period ended September 30, 2012, our revenues, depreciation and amortization, and pretax earnings included $16.0 million, $1.8 million, and $4.7 million, respectively, associated with the acquired operations of ERS after the closing in April 2012. In addition to the above impact on our results of operations, transaction costs associated with the ERS acquisition of approximately $0.5 million were also charged to general and administrative expense during the nine month period ended September 30, 2012.

Acquisition of Greywolf

On July 31, 2012, we acquired the assets and operations of Greywolf Production Systems Inc. and GPS Ltd. (together, Greywolf) for a cash purchase price of approximately $55.5 million. Greywolf is a provider of production testing and after-frac flow back services to oil and gas operators in western Canada and the U.S. Williston Basin (including the Bakken formation) and the Niobrara Shale formation of the U.S. Rocky Mountain region. This acquisition represented an additional strategic geographic expansion of our Production Testing segment operations.

We allocated the purchase price to the fair value of the assets acquired, which consisted of approximately $17.7 million of property, plant, and equipment, approximately $3.5 million of certain intangible assets, and approximately $34.3 million of nondeductible goodwill. The $34.3 million of goodwill recorded to our Production Testing segment as a result of the Greywolf acquisition is supported by the strategic benefits discussed above to be generated from the acquisition. For the nine month period ended September 30, 2012, our revenues, depreciation and amortization, and pretax earnings included $5.9 million, $0.4 million, and $1.2 million, respectively, associated with the acquired operations of Greywolf after the closing in July 2012. In addition to the above impact on our results of operations, transaction costs associated with the Greywolf acquisition of approximately $0.7 million were also charged to general and administrative expense during the nine month period ended September 30, 2012.

Compressco Partners' Bank Credit Facility

On May 14, 2013, Compressco Partners, L.P. (Compressco Partners) entered into an amendment of its bank credit facility whereby, among other modifications, the maximum credit commitment under the credit facility was increased from $20.0 million to $40.0 million.

On October 15, 2013, Compressco Partners entered into a new asset-based revolving credit facility with a syndicate of lenders including JPMorgan Chase Bank, N.A. as administrative agent (the Partnership Credit Agreement), which replaced Compressco Partners' previous credit agreement. Under the Partnership Credit Agreement, Compressco Partners, along with certain of its subsidiaries, are named as borrowers, and all obligations under the credit agreement are guaranteed by all of its existing and future, direct and indirect, domestic subsidiaries. We are not a borrower or a guarantor under the Partnership Credit Agreement. The Partnership Credit Agreement includes a maximum credit commitment of $100.0 million that is available for letters of credit (with a sublimit of $20.0 million), and includes an uncommitted $30.0 million expansion feature. The actual maximum credit availability under the Partnership Credit Agreement varies from time to time and is determined by calculating the applicable borrowing base, which is based upon applicable percentages of the values of eligible accounts receivable, inventory, and equipment, minus reserves as determined necessary by the Administrative Agent.

The Partnership Credit Agreement may be used to fund Compressco Partners' working capital needs, letters of credit, and for general partnership purposes, including the refinancing of Compressco Partners' previous credit facility, capital expenditures, and potential future expansions or acquisitions. So long as Compressco Partners is not in default, the Partnership Credit Agreement may also be used to fund Compressco Partners’ quarterly distributions at the option of the board of directors of the Partnership's general partner (provided, that after giving effect to such distributions, the borrowers will be in compliance with the financial covenants). The initial borrowings under the Partnership Credit Agreement of $24.5 million were used to repay in full all amounts outstanding under the previous credit facility dated June 24, 2011. Borrowings under the Partnership Credit Facility are subject to the satisfaction of customary conditions, including the absence of a default. The maturity date of the Partnership Credit Agreement is October 15, 2017.

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 selected by Compressco Partners), 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 per annum 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 outstanding principal under the Partnership Credit Agreement, Compressco Partners is required to pay a commitment fee, in respect of the unutilized commitments thereunder, of 0.375% per annum, paid quarterly in arrears. Compressco Partners is also required to pay a customary 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 4.0 to 1.0 as of the last day of any fiscal quarter, calculated on a trailing four quarters basis. 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 and subordinated units, but only if there is no default or event of default under the facility.

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).

NOTE D – 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 properties and platforms owned by our Maritech subsidiary, including the decommissioning and debris removal costs associated with one remaining offshore platform

12

previously destroyed by a hurricane. The amount of decommissioning liabilities recorded by Maritech is reduced by amounts allocable to joint interest owners. We also operate facilities in various U.S. and foreign locations that are used in the manufacture, storage, and sale of our products, inventories, and equipment. These facilities are a combination of owned and leased assets. We are required to take certain actions in connection with the retirement of these assets. The value of our asset retirement obligations for non-Maritech properties was approximately $8.0 million and $7.5 million as of September 30, 2013, and December 31, 2012, respectively. The changes in consolidated asset retirement obligations during the three and nine month periods ended September 30, 2013, are as follows:

	Three Months Ended   September 30, 2013			Nine Months Ended   September 30, 2013
	(In Thousands)
Beginning balance for the period, as reported	$	57,330		$	94,921
Activity in the period:
Accretion of liability	173			504
Revisions in estimated cash flows	21,538			54,404
Settlement of retirement obligations	(33,738		)	(104,526		)
Ending balance as of September 30	$	45,303		$	45,303

Revisions in estimated cash flows during the first nine months of 2013 resulted primarily from additional workincurred andanticipated to be required on Maritech’s offshore oil and gas properties. Settlements of asset retirement obligations during the three and nine month periods ended September 30, 2013, include approximately $5.3 million of obligations associated with oil and gas properties that were sold by Maritech during the period.

NOTE E – MARKET RISKS AND DERIVATIVEANDHEDGE 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, 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. Our financial risk management activities may at times involve, among other measures, the use of derivative financial instruments, such as swap and collaragreements, to hedge the impact of market price risk exposures. For hedge contracts qualifying for hedge accounting treatment, we formally document the 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.

In July 2012, we borrowed 10.0 million euros (approximately $13.5 million equivalent as of September 30, 2013) and designated the borrowing as a hedge of our net investment in our European operations. Changes in the foreigncurrency exchange rate have resulted in a cumulative change to the cumulative translation adjustment account of $0.9 million, net of taxes, at September 30, 2013, including a change of $0.3 million, net of taxes, during the nine months ended September 30, 2013, with no ineffectiveness recorded.

In October 2013, we and Compressco Partners each entered into foreign currency forward sale derivative contracts as part of a program designed to mitigate the currency exchange rate risk exposure on selected transactions for our Mexico subsidiaries. We entered into an approximately $10.5 million equivalent nominal value sale of U.S. dollars in November 2013, and Compressco Partners entered into an approximately $6.1 million equivalent nominal value sale of Mexican pesos in November 2013, at fixed exchange rates. Under this program, we and Compressco Partners may enter into similar derivative contracts from time to time. Although contracts pursuant to this program will serve as an economic hedge of the cash flow of our currency exchange risk exposure, they will not be formally designated as hedge contracts or qualify for hedge accounting treatment. Accordingly, any change in the fair value of these derivative instruments during a period will be included in the determination of earnings for that period.

NOTE G – COMMITMENTS AND CONTINGENCIES

Litigation

We are named defendants in several lawsuits and respondents in certain 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 consider it reasonably possible that a loss resulting from such lawsuits or other proceedings in excess of any amounts accrued has been incurred that is expected to have a material adverse impact on our financial condition, results of operations, or liquidity.

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 styledIn 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.While the outcome cannot be predicted with certainty, management does not consider it reasonably possible that a loss in excess of any amounts accrued has been incurred or is expected to have a material adverse impact on our financial condition, results of operations, or liquidity.

NOTE H – INDUSTRY SEGMENTS

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

Our Fluids Division manufactures and markets clear brine fluids, additives, and 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 or purchased from third-party suppliers to a variety of markets outside the energy industry.The Fluids Division also provides domestic onshore oil and gas operators with comprehensive frac water management services.

Our Production Enhancement Division consists of two operating segments: Production Testing and Compressco. The Production Testing segment provides after-frac flow back, production well testing, offshore rig cooling, and other associated services in many of the major oil and gas basins in the United States, Mexico, and Canada, as well as in certain basins in certain regions in South America, Africa, Europe, the Middle East, and Australia.

The Compressco segment provides compression-based production enhancement services, which are used in both conventional wellhead compression applications and unconventional compression applications, and in certain circumstances, well monitoring and sand separation services. Compressco provides these services throughout many of the onshore oil and gas producing regions of the United States, as well as certain basins in Mexico, Canada, and certain countries in South America, Eastern Europe, and the Asia-Pacific region. Beginning June 20, 2011, following the initial public offering of Compressco Partners, we allocate and charge certain corporate and divisional direct and indirect administrative costs to Compressco Partners.

Our Offshore Division consists of two operating segments: Offshore Services and Maritech. The Offshore Services segment provides (1) downhole and subsea oil and gas well plugging and abandonment services, (2) decommissioning and certain construction services utilizing heavy lift barges and various cutting technologies with regard to offshore oil and gas production platforms and pipelines, and (3) conventional and saturated air diving services.

The Maritech segment is an oil and gas production operation. During 2011 and the first quarter of 2012, Maritech sold substantially all of its oil and gas producing property interests. Maritech’s operations consist primarily of the ongoing abandonment and decommissioning associated with its remaining offshore wells, facilities, and production platforms. Maritech intends to acquire a significant portion of the services necessary to abandon and decommission these properties from the Offshore Division’s Offshore Services segment.

We generally evaluate the performance of and allocate resources to our segments based on profit or loss from their 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.

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

Business Overview  

Strategic efforts begun during late 2012 and the first half of 2013 have resulted in improved operating results and cash flow generation that were evident during the third quarter of 2013. Despite certain markets that continue to be challenging, overall consolidated revenues increased during the quarter compared to the prior year period, primarily due to the strong performance of our Fluids and Offshore Services segments. Our Fluids Division generated a significant portion of this growth in revenues and profitability compared to the prior year period due to increased sales of manufactured products, the continuing growth of its onshore frac water management business, and the strong demand for its clear brine fluids (CBF) products in the U.S. Gulf of Mexico. Our Offshore Services segment also reported increased revenues and profitability due to increased demand in activity during the quarter and the impact of cost reduction efforts taken in prior quarters that have resulted in increased gross profit and reduced administrative expenses. Despite decreased activity and continuing uncertainties in Mexico, our Compressco segment reported increased revenues, and offset much of the decreased profitability in Mexico by continuing to grow its U.S. compression services business, particularly its unconventional compression services applications business. Our Production Testing segment continues to face challenges in several of its markets, including Mexico, Canada, and selected regions in the U.S. Our Maritech segment reported increased losses due to increased excess decommissioning costs expensed during the third quarter of 2013. Overall, the cost reduction efforts taken during the second quarter of 2013 have contributed to increased profitability and operating cash flow for each of our segments. Efforts to streamline and improve invoicing and collection processes have also improved our operating cash flow. The improvements in operating cash flow levels have enabled us to fund the majority of our overall growth, while we also continue to aggressively pursue the extinguishment of Maritech's remaining decommissioning liabilities. Despite recent adjustments to the work required to be performed, Maritech's decommissioning liabilities have been reduced to approximately $37.3 million as of September 30, 2013.

Consolidated operating cash flows during the nine months ended September 30, 2013, increased approximately $61.4 million compared to the prior year period. This increase is despite the $33.2 million increase in amounts expended on Maritech decommissioning liabilities. These increased operating cash flows, along with available cash balances, were used to fund much of theapproximately $73.6 million of capital expenditures during this period. To fund additional future growth, as of November 7, 2013, we have approximately $224.8 million available under our revolving credit facility. In October 2013, Compressco Partners, L.P. (Compressco Partners) entered into a new asset-based bank revolving credit facility, increasing its maximum credit commitment to $100.0 million, with an additional $30.0 million uncommitted expansion feature, which will be available to fund its growth. In addition to the ongoing capital expenditure activity, we continue to evaluate opportunities to further expand certain of our businesses through acquisitions, consistent with our ongoing growth plan.

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, 2012. 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 revenuesfor the quarter ended September 30, 2013, increased compared to the prior year period due to increased revenuesfor the Fluids, Offshore Services, and Compresscosegments. The increase in the Fluids Division revenues was primarily due to increased sales of manufactured products and clear brine fluids (CBF) products in the U.S. The increase in Offshore Services revenues was primarily due to increased dive services activity. The increase in Compressco revenues was primarily due to increased activity in the U.S. and Canada, which more than offset decreased activity in Mexico. These increases were partially offset by decreased Production Testing activity in several of its most significant markets served, including in the U.S., Canada, and Mexico. Any future increases in Compressco and Production Testing segment revenue levels in Mexico are dependent on the resolution of current uncertainties with their primary customer in Mexico. Consolidated gross profit decreased during the current year quarter compared to the prior year period, primarily due to $12.3 million of increased Maritech excess decommissioning expenses as well as the decreased gross profit of our Production Testing segment. These decreases in profitability were largely offset by the increased profitability of our Fluids and Offshore Services segments. These increases were due to the increased product sales revenues of the Fluids segment and the increased demand for services and the impact of cost reduction efforts by our Offshore Services segment.

Consolidated general and administrative expenses decreased during the third quarter of 2013compared to the prior year period primarily due to cost reduction efforts taken by each of our segments during the second quarter of 2013 to reduce administrative expenses. In particular, our Offshore Services segment reported $1.7 million of decreased general and administrative expense during the third quarter of 2013 compared to the prior year period. Reductions of personnel-related expenses as a result of cost reduction efforts were supplemented by additional decreases in professional services expenses as well as other general expenses. Largely due to the impact of these administrative cost reduction efforts taken during the first half of 2013, consolidated general and administrative expenses decreased by approximately $2.2 million compared to the prior quarter.

Consolidated interest expensedecreased slightly, as decreased interest on Senior Notes borrowings more than offset the increase due to increased Compressco Partners' borrowings.

20

Consolidated other income increased primarily due to increased gains on sale of assets, primarily from a sale of a Maritech property during the current year period.

The consolidated provision for income taxes increased due to increased earnings during the period.

The increase in Fluids Division revenues during the third quarter of 2013 compared to the prior year period was primarily due to approximately $17.5 million of increased product sales revenues, mainly due to significant sales of calcium chloride by the Division's manufactured products operation. A portion of these increased manufactured product sales was due to increased demand in selected markets and due to nonrecurring demand from a single U.S. customer during the period. In addition, the Division's sales of CBF products also increased due to a significant increase in offshore completion activity in the U.S. Gulf of Mexico. The Division's services revenues increased by approximately $6.9 million, due to the growth of our U.S. onshore frac water management business.

Fluids Division gross profit increased compared to the prior year period, primarily as a result of the increased product sales activity discussed above. Operating efficiencies of our El Dorado, Arkansas, calcium chloride plant facility were optimized due to increased production volumes at the plant. Increased water management service activity also contributed to the increased gross profit.

Fluids Division income before taxes increased compared to the prior year period due to the increase in gross profit discussed above. This increase was partially offset by increased administrative costs and decreased other income compared to the prior year period.

Production Testing segment revenues decreased during the third quarter of 2013 compared to the prior year period, primarily due to a $6.6 million decrease in U.S. and Canadian revenues as a result of decreased activity and pricing levels, largely as a result of increased competition in certain of the U.S. and Canadian markets we serve. These decreases occurred despite increased activity in U.S. regions served by our ERS and Greywolf businesses, both of which were acquired during 2012. Foreign Production Testing segment revenues also decreased as compared to the prior year period, as increased activity in the Eastern Hemisphere was more than offset by the impact of decreased demand from our primary customer in Mexico due to budget re-evaluations affecting the northern region of Mexico. We believe this decline in demand in Mexico is temporary, and we have begun to see a slow increase in activity levels in Mexico.

Production Testing segment gross profit decreased significantly during the third quarter of 2013 compared to the prior year period due to the impact of the above mentioned decreased activity and pricing levels in certain U.S. and Canadian markets and the decreased Mexico activity levels. During the second quarter of 2013, we took steps to downsize field operations and implement other cost reductions for the Production Testing segment. In response to the decreased activity in certain U.S. markets, we are currently implementing additional cost reduction steps, including the relocation of equipment and other resources, that are expected to result in further operating expense reductions beginning in the fourth quarter of 2013.

Production Testing segment income before taxes decreased primarily due to the significant decrease in gross profit discussed above. This decrease in profitability was partially offset by increased other income that resulted from increased earnings from an unconsolidated joint venture and from decreased foreign currency losses. Production Testing segment general and administrative expenses also decreased due to the impact of administrative cost reductions and due to acquisition related costs expensed during the prior year period.

Compressco segment revenues increased during the third quarter of 2013 compared to the prior year period due to a $0.9 million increase in service revenues, primarily from increased activity in the U.S. and Argentina. The increase in U.S. service revenues was due to Compressco's increased unconventional compression services applications activity, primarily in horizontal resource play reservoirs. The increase in total Compressco revenues was realized despite decreased revenues in Mexico compared to the prior year period caused by the current budgetre-evaluations by Compressco's primary customer in Mexico. In March 2013,Compressco began to experience adecline in demand in the northern region of Mexico for itsoil and gas services from this customer. Compresscobelieves this decline in demand is temporary and has begun to see a slow increase in activity levels in Mexico. Compressco has continued to increase its compressor fleet, both in the U.S. and certain foreign markets, to serve increasing demand for services. Revenues from the sales of compressor units and parts during the third quarter of 2013 were flat compared to the prior year period.

Compressco segment gross profit decreased during the third quarter of 2013 compared to the prior year period, primarily due to the impact of the reduced revenues in Mexico and increased labor and maintenance costs. Average compressor unit utilization increased from 82.0% to 84.2%, although gross profit as a percentage of revenue decreased compared to the prior year period as a result of the increased costs and the impact of the decreased activity in Mexico. Primarily as a result of the current reduced activity described above, Compressco reduced its Mexico operating headcount and relocated equipment to the U.S. during the second and third quarters of 2013.

Income before taxes for the Compressco segment decreased during the third quarter of 2013 compared to the prior year period, primarily due to the decreased gross profit discussed above and from increased interest expense as a result of increased borrowings by Compressco Partners under its bank credit facility. This decrease in profitability was partially offset by decreased administrative costs and decreased other expense. Compressco’s administrative expense levels decreased compared to the prior year period, primarily due to decreased personnel related costs, which more than offset the increase in professional services expenses during the current year period. Other expense decreased primarily due to decreased foreign currency losses compared to the prior year period.

Revenues from the Offshore Services segment increased during the third quarter of 2013 compared to the prior year quarter primarily due to increased activity levels for its dive services operations, partly as a result of projects that were delayed from the second quarter of 2013. Increased well abandonment activity during the current year quarter also contributed to the increased revenues. These increases in Offshore Services segment revenues were partially offset by decreased revenues by its cutting services and heavy lift operations, partly due to difficult weather experienced in September 2013. Offshore Services revenues during the three months ended September 30, 2013 and 2012 include approximately $10.0 million and $5.8 million, respectively, of revenues related to work performed for Maritech. The level of such Maritech work is expected to significantly decrease beginning in 2014.

Gross profit for the Offshore Services segment increased due to the increased activity levels for the dive services and well abandonment businesses compared to the prior year period, but also as a result of the cost reduction measures that were implemented during late 2012 and the first half of 2013. With its streamlined operating cost structure, the Offshore Services segment's gross profit as a percentage of segment revenues increased to 27.6% during the current year quarter compared to 22.2% during the prior year period. The Offshore Services segment continues to consider additional opportunities to optimize its cost structure.

Offshore Services segment income before taxes increased, primarily due to the increased gross profit discussed above. In addition, segment general and administrative expenses were decreased, reflecting the administrative cost reductions taken during late 2012 and first half of 2013. In addition, other expense decreased compared to the prior year period, primarily due to decreased foreign currency losses.

As a result of the sale of almost all of its producing properties during 2011 and 2012, Maritech revenues for the third quarter of 2013 and 2012 are negligible and are expected to continue to be negligible going forward.

Maritech gross loss increased during the third quarter of 2013 compared to the prior year period due to approximately $21.5 million of excess decommissioning costs expensed during the current year period, including approximately $10.0 million associated with work to be performed during future periods. The amount expensed during the current year period reflects an increase of approximately $12.3 million of such costs compared to the prior year period and was due to additional oil and gas abandonment and decommissioning work required on certain offshore properties, including remediation work required on certain wells that had been previously plugged.

The increase in Maritech’s pretax loss during the third quarter of 2013 compared to the prior year period is primarily due to the increased gross loss discussed above. Partially offsetting this decrease, Maritech sold its interest in one of its remaining offshore oil and gas properties, resulting in a gain of approximately $5.4 million during the current year period.

Corporate Overhead decreased during the third quarter of 2013compared to the prior year period, due to decreased corporate general and administrative, depreciation, and interest expenses. Corporate general and administrative expenses decreased as approximately $0.7 million of increased office expense was more than offset by decreased salary and employee-related expenses as a result of cost reduction efforts taken earlier during the year. Increased office expense was primarily the result of the sale and leaseback of our corporate headquarters building in the fourth quarter of 2012, which also resulted in decreased depreciation compared to the prior year period. In addition, interest expense decreased due to the second quarter 2013 issuance of the 4.0% Senior Notes Series 2013, the proceeds of which were used to repay the 6.3% Series 2008-A Senior Notes. Partially offsetting these decreases was the increase in other expense due to increased foreign currency losses.

Consolidated revenuesfor the nine months ended September 30, 2013, increased compared to the prior year period due to increased revenuesfor our Fluids, Production Testing, andCompresscosegments.The increase in theFluidsDivision’srevenuesisdue to increased demand for our manufactured products, the growth of our onshore frac water management business, and the increased activity for U.S. offshore CBF product sales.Our Compressco segment reportedincreased revenues during the nine month perioddueto increased activity in Latin America and increased demand for unconventional compression services applications in the U.S. Our Production Testing segment revenues also increased, reflecting the impact of 2012 acquisitions. The impact on segment revenues from these acquisitions more than offset the decreased Production Testing segment revenues resulting from decreased activity experienced in several of the markets it serves, including in Mexico.Any future increases in the Compressco and Production Testing segments' activity levels in Mexico are subject to the resolution of current uncertainties with our primary customer in Mexico. The increased consolidated revenues were negatively affected by our Offshore Services segment, which reporteddecreased revenues for the current year period due toa reduction in heavy lift and diveservicesactivity. These businesses were also adversely affected byweather delays during the second and third quarters of 2013 as well as by continuingmarket challengesin the U.S. Gulf of Mexico during the first half of the current year. Consolidated gross profit decreased, despite the increased profitability of our Fluids and Offshore Services segments, as our Maritech and Production Testing segments reported decreases. Maritech expensed approximately $54.4 million of excess decommissioning costs during the current year period.

Consolidated general and administrative expenses increased during the first nine months of 2013compared to the prior year period due to approximately $1.8 million of increased general and administrative expensesbyour Production Testing segment, primarily as a result of the businesses acquired during 2012. Consolidated general and administrative expenses also increased as a result of approximately $1.3 million of employee severance expenses recorded during the second quarter of 2013. In addition, our Maritech segment's general and administrative expenses increased approximately $0.8 million, primarily due to legal expenses associated with an insurance-related settlement during the first quarter of 2013. These increases, along with the impact from the growth of our Fluids Division, were partially offset by our Offshore Services segment, where general and administrative costs decreased by $2.1 million, primarily due to the cost reduction steps taken during late 2012 and the second quarter of 2013. Overall, cost reduction efforts taken by each of our segments have resulted in reduced administrative cost levels beginning in the third quarter of 2013. 

26

Consolidated interest expenseincreased slightly during the first nine months of 2013 primarily due to increased Compressco borrowings.

Consolidated other income increased primarily due to $3.9 million of increased earnings from an unconsolidated joint venture and from $2.4 million ofincreased gains on sale of assets.

The consolidated provision for income taxes decreased compared to the prior year period due to decreased earnings.

The increase in Fluids Division revenues during the nine months ended September 30, 2013, compared to the prior year period was primarily due to approximately $27.1 million of increased product sales revenue, primarily due to the increased demand for its calcium chloride manufactured products as well as increased sales of brominated products. In addition, Fluids Division product sales also reflect the increased U.S. offshore demand for its CBF products, as U.S. Gulf of Mexico drilling and completion activity levels have continued to increase in 2013 compared to the prior year period. In addition, the Division also reported approximately $22.5 million of increased service revenues from the growth of its onshore frac water management business.

Fluids Division gross profit increased compared to the prior year period primarily as a result of theincreased demand for U.S. onshore frac water management activity, the increased demand for manufactured products,and increasedGulf of Mexico CBF product sales discussed above.

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. Fluids Division administrative costs increased primarily due to increasedpersonnel-related costs, partially offset by decreased professional fee expenses. In addition, other income decreased due to decreased foreign currency gains.

Production Testing segment revenues increased during the first nine months of 2013 compared to the prior year period due to the acquisitions ofOPTIMA,ERS, andGreywolf during 2012. This increase, which occurred despite decreased Greywolf Canadian activity in the current year period compared to late 2012 levels, was largely offset by the significant decrease of our previously existing production testing business. This decrease in revenues from our previously existing production testing business was primarilydue to decreased activity and pricing levels, largely as a result of increased competition in certain of the U.S. markets we serve. In addition, Production Testing segment revenues decreased due to the impact of reduced activity in the northern region of Mexico caused by current budget re-evaluations by the segment's primary customer in Mexico. We believe this decline in demand is temporary, and we have begun to see a slow increase in activity levels in Mexico. Decreased revenues in Mexico were also caused by decreased demand during the first quarter of 2013 for certain of the segment's production testing services, a portion of which was offset, on a consolidated basis, by increased demand for well monitoring services during the first quarter of 2013 by our Compressco segment. These decreases were partially offset by increased revenues from operations in the Eastern Hemisphere during the first nine months of 2013.

Production Testing segment gross profit decreased during the first nine months of 2013 compared to the prior year period despite the 2012 acquisitions ofOPTIMA, ERS, andGreywolf. The gross profit increase from the acquired businesses and the growth in certain of the segment's foreign operations was more than offset by the impact of the decreased activity and pricing levels in certain U.S. markets, increased labor costs, and the impact of the decreased production testing activity in Mexico compared to the prior year period. During the second quarter of 2013, we took steps to downsize field operations and implement other cost reductions for the Production Testing segment that have resulted in decreased operating expenses. In response to the decreased activity in certain U.S. markets, we are currently implementing additional cost reduction steps, including the relocation of equipment and other resources, that are expected to result in further operating expense reductions beginning in the fourth quarter of 2013.

Production Testing segment income before taxes decreased due to the decreased gross profit discussed above as well as from increased administrative expenses compared to the prior year period. The increased administrative expenses were primarily due to the increased personnel-related and other administrative costs associated with the acquired OPTIMA, ERS, and Greywolf businesses. These increases more than offset the decrease in professional services expenses, which included acquisition related costs during the prior year period. Partially offsetting the decreased gross profit and increased general and administrative expenses, other income increased, primarily due to increased earnings from an unconsolidated joint venture.

The increase in Compressco segment revenues compared to the prior year period was due to an increase of $11.5 million of service revenues, resulting primarily from increased activity in the U.S., Canada, and Argentina. The increase in the U.S. reflects the increased demand for unconventional compression services applications as a result of increased activity primarily in horizontal resource play reservoirs. Compressco segment service revenues also increased during the current year period due to increased activity in Mexico, primarily caused by increased activity during the first quarter of 2013. However, as a result of the budgetre-evaluations by Compressco's primary customer in Mexico, in March 2013Compressco began to experience adecline in demand for itsoil and gas services in the northern region of Mexico. We believe this decline in demand is temporary, and we have begun to see a slow increase in activity levels in Mexico. Compressco has continued to increase its compressor fleet, both in the U.S. and in certain foreign markets, to serve increasing demand. Revenues from the sales of compressor units and parts during the first nine months of 2013 increased $0.2 million compared to the prior year period.

Compressco segment gross profit decreased slightly during the first nine months of 2013 compared to the prior year period, as the increased U.S. and Latin America revenues were largely offset by increased operating expenses, particularly labor, maintenance, and fuel costs. Gross profit as a percentage of revenue decreased compared to the prior year period as a result of these cost increases. Primarily as a result of the current reduced activity in Mexico described above, Compressco has aggressively reduced its Mexico operating headcount and relocated certain equipment to the U.S. from Mexico.

Income before taxes for the Compressco segment decreased during the first nine months of 2013 compared to the prior year period due to the decreased gross profit discussed above. Interest expense increased due to the increased borrowings under the Compressco Partners bank credit facility during the current year period. Compressco’s administrative expense levels also increased compared to the prior year period due to increases in salaries and other employee related costs as well as increased professional services expenses. These increases were partially offset by decreased foreign currency losses compared to the prior year period.

Revenues from our Offshore Services segment decreased during the first nine months of 2013 compared to the prior year period, primarily due to decreased activity levels in the Gulf of Mexico market for its heavy lift and cutting services businesses. These businesses were also negatively affected by weather delays during the period, including unseasonal weather delays during the second and third quarters. Activity levels, particularly for the dive service business, have increased during the current year period compared to the prior year period due to increased activity during the third quarter of 2013. Offshore Services revenues during the nine months ended September 30, 2013 and 2012 include approximately $39.7 million and $25.5 million, respectively, of revenues related to work performed for Maritech. The level of such Maritech work is expected to significantly decrease beginning in 2014.

Despite the decrease in revenues for the Offshore Services segment during the first nine months of 2013, gross profit increased compared to the prior year period. Gross profit as a percentage of revenues increased to 18.8% during the current year period compared to 15.4% during the prior year period. This increased profitability primarily reflects the impact of cost reduction efforts made during late 2012 and the second quarter of 2013. As a result of these cost reduction efforts, profitability for the segment has increased despite market conditions that continue to be challenging, including the impact of increased competition and decreased pricing compared to the prior year period. In addition, the impact of weather delays during a portion of the current year period negatively affected profitability. The Offshore Services segment continues to consider additional opportunities to optimize its cost structure.

Offshore Services segment income before taxes increased, primarily due to the increased gross profit discussed above and despite decreased other income. Other income decreased due to a $4.1 million gain on sale of certain abandonment assets during the prior year period. Offshore Services administrative costs decreased, primarily as a result of the segment’s cost reduction efforts, which reduced salary and personnel-related expenses, and more than offset approximately $0.3 million of severance costs expensed during the second quarter of 2013.

As a result of the sale of almost all of its producing properties during 2011 and 2012, Maritech revenues for the first nine months of 2013 and 2012 are negligible and are expected to continue to be negligible going forward.

Maritech gross loss increased during the first nine months of 2013 due to approximately $54.4 million of excess decommissioning costs expensed during the current year period, an increase of approximately $35.3 million compared to the prior year period. Revisions in estimated decommissioning liability cash flows during the first nine months of 2013 resulted primarily from additional workincurred andanticipated to be required on Maritech’s offshore oil and gas properties, including remediation work required on certain wells that had been previously plugged. Partially offsetting the increased costs, approximately $5.6 million was credited to operating expenses during the first quarter of 2013 associated with the net impact of an insurance-related litigation settlement recorded in the current year period.

The increase in Maritech’s pretax loss during the first nine months of 2013 compared to the prior year period is primarily due to the increased gross loss discussed above. The increase in general and administrative expenses is primarily due to the professional fees associated with the insurance-related litigation settlement received during the first quarter. Other income increased significantly during the current year period, due to the approximately $5.4 million gain recognized on the sale of one of Maritech's remaining offshore oil and gas properties during the third quarter of 2013.

Corporate Overhead increased during the nine months ended September 30, 2013,compared to the prior year period, primarily due to increasedcorporate general and administrative expenses, which increased primarily due to approximately $2.0 million of increased office expense. The increased office expense was a result of the sale and leaseback of our corporate headquarters building in the fourth quarter of 2012. These increases were partially offset by approximately $0.7 million of decreased personnel-related expenses and $0.4 million of increased allocations. The decreased personnel-related expenses were as a result of second quarter 2013 cost reduction efforts and more than offset approximately $0.5 million of associated severance costs incurred during that period. Depreciation expense decreased compared to the prior year period due to the sale and leaseback of our corporate headquarters building discussed above.

Liquidity and Capital Resources

Increased operating cash flows during the first nine months of 2013 compared to the prior year period reflect the impact of strategic initiatives to reduce costs and streamline our customer billing and collection processes. Cost reduction efforts taken during the second quarter of 2013 and late 2012 resulted in improved profitability and cash flows for each of our segments. The increased operating cash flows have allowed us to continue to aggressively pursue extinguishing Maritech's remaining decommissioning liabilities, fund capital expenditure activity, and further strengthen our balance sheet. As of September 30, 2013, and after expending approximately $99.4 million during the first nine months of 2013 on decommissioning and associated work, Maritech's remaining decommissioning liabilities have been reduced to approximately $37.3 million. A large amount of the remaining work to be performed is expected to be performed during the fourth quarter of 2013. With the remaining amount of Maritech decommissioning work expected to decrease significantly, we anticipate the resulting increase in operating cash flows beginning in 2014 will provide significant opportunities to continue to strengthen our balance sheet and strategically grow our businesses. Through September 30, 2013, we spent an aggregate of approximately $73.6million on capital expenditure activity for several of our existing businesses. In addition to the ongoing capital expenditure activity, we continue to evaluate opportunities to further expand certain of our businesses through acquisitions, consistent with our growth plan. In addition to available cash, as of November 7, 2013, we have approximately $224.8 million available under our revolving credit facility to fund our future strategic growth.

Operating Activities

Cash flowsgeneratedby operating activitiestotaled $43.9millionduring the first nine months of 2013 compared to $17.4 million of cashusedby operating activities during the prior year period,an increaseof $61.4million. Thisincrease in operating cash flows during 2013compared to the prior year periodwas largely due toan improvement of approximately $68.2 million from the collection of accounts receivable, reflecting an effort begun during late 2012 to expedite collections. This increase in cash provided by operating activities was generated despite approximately $99.4 million of decommissioning activity performed during the nine months ended September 30, 2013, an increase of $33.2 million compared to the prior year period. A portion of the decommissioning activity performed during the current year period was associated with approximately $54.4 million of excess decommissioning costs charged to earnings during the period.

Maritechcontinues to performan extensive amount of well abandonment and decommissioning work associated with itsremainingoffshore oil and gas production wells, platforms, and facilities. As of September 30, 2013, and including the impact of adjustments to the estimated work remaining to be performed that were caused by certain required remediation work, Maritech’s decommissioning liabilities totaled approximately $37.3million. Until the remaining decommissioning liabilities are extinguished, our future operating cash flows will continue to be affected by the actual timing and amount of Maritech’s decommissioning expenditures.Most ofthe cash outflow necessary to extinguish Maritech’s remaining decommissioning liabilitiesis expected to occurduring the fourth quarter of 2013, subject to weather conditions and regulatory approvals. Included in Maritech’s decommissioning liabilities is the remaining abandonment, decommissioning, and debris removal associated with one offshore platform that was previously destroyed byahurricane as well as certain remediation work required on wells that had been previously plugged. Due to the unique nature of the remaining work to be performed associated with these properties, actual costs could greatly exceed these estimates and could result in significant charges to earnings in future periods.

During late 2012 and the first half of 2013, each of our segments implemented operating and administrative cost reductions, including reductions in headcount, that were designed to streamline our operations and downsize our organization, particularly in our corporate headquarters and in certain of our businesses. Together with the specific cost reduction steps taken by our Offshore Services segment in late 2012, these cost reduction efforts have resulted in increased operating cash flows and improved profitability, which are expected to continue going forward. We continue to review our overall operating and administrative cost structure in order to identify additional opportunities to reduce costs.

We are subject to operating hazards normally associated with onshore and offshore oilfield service operations, including fires, explosions, blowouts, cratering, mechanical problems, abnormally pressured formations, and accidents that cause harm to the environment.In addition, in the performance of each of our operations we are exposed to additional hazards, including personal injuries and vehicle-related accidents.We maintain various types of insurance that are designed to be applicable in the event of an explosion or other catastrophic event involving our

32

offshore operations. This insurance includes third-party liability, workers’ compensation and employers’ liability,automobile 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 is subject to deductibles that must be satisfied prior to recovery. Additionally, our insurance is subject to certain exclusions and limitations. 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 is submitted to theBureau of Safety and Environmental Enforcement (BSEE). Maritech has designated third-party contractors 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 2013, the total amount of our net cash utilized on investing activities was $71.8 million. Total cashcapital expenditures during the first nine months of 2013 were $73.6 million. Approximately $30.5 million of our capital expenditures during the first nine months of 2013 was spent by our Fluids Division, the majority of which related to the purchase of new equipment to support its frac water management business. Our Production Enhancement Division spent approximately $38.8 million on capital expenditures, consisting of approximately $20.0 million by the Production Testing segment to add or replace a portion of its production testing equipment fleet, and approximately $18.8 million by the Compressco segment for the upgrade and expansion of its wellhead compressor and equipment fleet. Our Offshore Services segment spent approximately $3.5 million on its various heavy lift and dive support vessels. Corporate capital expenditures were approximately $0.7 million.

In October 2013, we entered into an agreement to acquire the remaining 50% ownership interest of Ahmad Albinali & TETRA Arabia Company Ltd., a Saudi Arabian limited liability company. The closing for the transaction, which is subject to customary approvals by Saudi Arabian governmental agencies as well as other conditions, is expected to occur during the fourth quarter of 2013 or early 2014. Following the closing of this transaction, the Saudi Arabian limited liability company will become a wholly owned consolidated subsidiary.

Generally, a significant majority of our planned capital expenditures is related to identified opportunities to grow and expand our existing businesses (other than Maritech). However, certain of these planned expenditures may be postponed or canceled in an effort to conserve capital or otherwise address future market conditions. Although our planned level of capital expenditures during the remainder of 2013 is subject to the impact of acquisitions and future market conditions, we currently plan toexpend up to approximately $100 millionon total capital expenditures (excluding acquisitions) during 2013. The deferral of capital projects could affect our ability to compete in the future. To the extent we consummate an additional significant acquisition transaction or other capital project, our liquidity position and capital plans 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, operating leases, equity issuances, and other sources of capital.

Our Bank Credit Facilities

We have a $278 million 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 7, 2013, we had an outstanding balance on the revolving credit facility of approximately $44.6million, andhad $8.6 million in letters of credit and guaranteesagainst therevolving credit facility, leaving a net availability of $224.8 million. In addition, the Credit 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. Approximately $13.5 million of the $23.5 million outstanding borrowings under the revolving credit facility as of September 30, 2013, is denominated in euros, which has been designated as a hedge of the net investment in our European operations.

33

Under the Credit Agreement, which matures on October 29, 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 based on 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 line is dependent upon our compliance with the financial ratio covenants set forth in the Credit Agreement. Significant deterioration of the financial ratios could result in a default by us under the Credit Agreement and, if not remedied, could result in termination of the Credit Agreement and acceleration of any outstanding balances. Compressco is an unrestricted subsidiary and is not a borrower or a guarantor under our bank credit facility.

The Credit Agreement 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, 2013. 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.

Our European Credit Agreement

We also have a bank line of credit agreement to cover the day to day working capital needs of certain of our European operations (the European Credit Agreement). The European Credit Agreement provides borrowing capacity of up to 5 million euros (approximately $6.8 million equivalent as of September 30, 2013) with interest computed on any outstanding borrowings at a rate equal to the lender’s Basis Rate plus 0.75%. The European Credit Agreement is cancellable by either party with 14-business-days notice and contains standard provisions in the event of default. As of September 30, 2013, we had no borrowings outstanding pursuant to the European Credit Agreement.

Compressco Partners’ Bank Credit Facility

On June 24, 2011, Compressco Partners entered into a credit agreement (the Partnership Credit Agreement) with JPMorgan Chase Bank, N.A., which was amended on December 4, 2012, and May 14, 2013. Under the Partnership Credit Agreement, as amended, Compressco Partners, along with certain of its subsidiaries, were named as borrowers, and all of its existing and future, direct and indirect, domestic subsidiaries were guarantors. We were not a borrower or a guarantor under the Partnership Credit Agreement. The Partnership Credit Agreement, as amended, included a maximum credit commitment of $40.0 million, that was available for letters of credit (with a sublimit of $5.0 million), and included an uncommitted $20.0 million expansion feature. Compressco Partners was in compliance with the covenants and conditions of the Partnership Credit Agreement as of September 30, 2013.

On October 15, 2013, Compressco Partners entered into a new asset-based revolving credit facility with a syndicate of lenders including JPMorgan Chase Bank, N.A. as administrative agent (the New Partnership Credit Agreement), which replaced the previous Partnership Credit Agreement. Under the New Partnership Credit Agreement, Compressco Partners, along with certain of its subsidiaries, are named as borrowers, and all obligations under the credit agreement are guaranteed by all of its existing and future, direct and indirect, domestic subsidiaries. We are not a borrower or a guarantor under the New Partnership Credit Agreement. The New Partnership Credit Agreement includes a maximum credit commitment of $100.0 million that is available for letters of credit (with a sublimit of $20.0 million), and includes an uncommitted $30.0 million expansion feature. The actual maximum credit availability under the New Partnership Credit Agreement varies from time to time and is determined by calculating the applicable borrowing base, which is based upon applicable percentages of the values of eligible accounts receivable, inventory, and equipment, minus reserves as determined necessary by the Administrative Agent. As of November 7, 2013, Compressco Partners has a balance outstanding under the New Partnership Credit Agreement of $24.5 million and had availability under the New Partnership Credit Facility of $40.9 million, based upon a $65.6 million borrowing base and the $24.5 million outstanding balance.

34

The New Partnership Credit Agreement may be used to fund Compressco Partners' working capital needs, letters of credit, and for general partnership purposes, including the refinancing of the previous credit facility, capital expenditures, and potential future expansions or acquisitions. So long as Compressco Partners is not in default, the New Partnership Credit Agreement may also be used to fund Compressco Partners’ quarterly distributions at the option of the board of directors of the Partnership's general partner (provided, that after giving effect to such distributions, the borrowers will be in compliance with the financial covenants). The initial borrowings under the New Partnership Credit Agreement of $24.5 million were used to repay in full all amounts outstanding under the previous credit agreement dated June 24, 2011. Borrowings under the New Partnership Credit Facility are subject to the satisfaction of customary conditions, including the absence of a default. The maturity date of the New Partnership Credit Agreement is October 15, 2017.

Borrowings under the New 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 selected by Compressco Partners), 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 per annum 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 outstanding principal under the New Partnership Credit Agreement, Compressco Partners is required to pay a commitment fee, in respect of the unutilized commitments thereunder, of 0.375% per annum, paid quarterly in arrears. Compressco Partners is also required to pay a customary letter of credit fee equal to the applicable margin on revolving credit LIBOR loans and fronting fees.

The New Partnership Credit Agreement requires Compressco Partners to maintain a minimum interest coverage ratio (ratio of earnings before interest and taxes to interest) of 4.0 to 1.0 as of the last day of any fiscal quarter, calculated on a trailing four quarters basis. In addition, the New 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 New Partnership Credit Agreement provides that Compressco Partners can make distributions to holders of its common and subordinated units, but only if there is no default or event of default under the facility.

All obligations under the New 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).

Senior Notes

In April 2006, we issued $90.0 million in aggregate principal amount of Series 2006-A Senior Notes pursuant to our existing Master Note Purchase Agreement dated September 2004, as supplemented as of April 18, 2006. The Series 2006-A Senior Notes bear interest at a 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 $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 April 30, 2008. The Series 2008-A Senior Notes bore interest at a fixed rate of 6.30% and matured and were repaid on April 30, 2013. The Series 2008-B Senior Notes bear interest at a 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 $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 a fixed rate of 5.09% and mature on December 15, 2017. The Series 2010-B Senior Notes bear interest at a 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.

In April 2013, we issued $35.0 million in aggregate principal amount of Series 2013 Senior Notes pursuant to a Note Purchase Agreement dated April 29, 2013. The Series 2013 Senior Notes bear interest at a fixed rate of

35

4.0% and mature on April 29, 2020. We utilized the proceeds from the issuance of the Series 2013 Senior Notes to repay the Series 2008-A Senior Notes in April 2013. 

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 Agreements 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, 2013. 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.

Other Sources and Uses

In addition to the aforementioned revolving credit facilities, we fund our short-term liquidity requirements from cash generated by operations, operating leases, and from short-term vendor financing. 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 for an indeterminable length of time. As discussed above, our Credit Agreement matures in October 2015, the New Partnership Credit Agreement matures in October 2017, and our Senior Notes mature at various dates between April 2015 and December 2020. The replacement of these capital sources at similar or more favorable terms is not certain. If it is necessary to issue equity to fund our capital needs, dilution to our common stockholders will occur.

Compressco Partners’ Partnership Agreement requires that within 45 days after the end of each quarter, it distribute all of its available cash, as defined in the Partnership Agreement, to its unitholders of record on the applicable record date. For the nine months ended September 30, 2013, Compressco Partners distributed approximately $3.6 million to its public unitholders.

Off Balance Sheet Arrangements

As of September 30, 2013, 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.

Senior Notes

On April 29, 2013, we issued $35.0 million in aggregate principal amount of Series 2013 Senior Notes pursuant to a Note Purchase Agreement. The Series 2013 Senior Notes bear interest at the fixed rate of 4.0% and mature on April 29, 2020. On April 30, 2013, we utilized the proceeds from the issuance to repay the 2008-A Senior Notes. The Series 2013 Senior Notes were sold in the United States to accredited investors pursuant to an exemption from the Securities Act of 1933. Interest on the Series 2013 Senior Notes is due semiannually on April 29 and October 29 of each year. Similar to each other series of our outstanding senior notes, the Series 2013 Senior Notes 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.

Compressco Partners' Bank Credit Facility

On May 14, 2013, Compressco Partners, L.P. (Compressco Partners) entered into an amendment of its bank credit facility whereby, among other modifications, the maximum credit commitment under the credit facility was increased from $20.0 million to $40.0 million.

On October 15, 2013, Compressco Partners entered into a new asset-based revolving credit facility with a syndicate of lenders including JPMorgan Chase Bank, N.A. as administrative agent (the Partnership Credit Agreement), which replaced Compressco Partners' previous credit agreement. Under the Partnership Credit Agreement, Compressco Partners, along with certain of its subsidiaries, are named as borrowers, and all obligations under the credit agreement are guaranteed by all of its existing and future, direct and indirect, domestic subsidiaries. We are not a borrower or a guarantor under the Partnership Credit Agreement. The Partnership Credit Agreement includes a maximum credit commitment of $100.0 million that is available for letters of credit (with a sublimit of $20.0 million), and includes an uncommitted $30.0 million expansion feature. The actual maximum credit availability under the Partnership Credit Agreement varies from time to time and is determined by calculating the applicable borrowing base, which is based upon applicable percentages of the values of eligible accounts receivable, inventory, and equipment, minus reserves as determined necessary by the Administrative Agent.

The Partnership Credit Agreement may be used to fund Compressco Partners' working capital needs, letters of credit, and for general partnership purposes, including the refinancing of Compressco Partners' previous credit facility, capital expenditures, and potential future expansions or acquisitions. So long as Compressco Partners is not in default, the Partnership Credit Agreement may also be used to fund Compressco Partners’ quarterly distributions at the option of the board of directors of the Partnership's general partner (provided, that after giving effect to such distributions, the borrowers will be in compliance with the financial covenants). The initial borrowings under the Partnership Credit Agreement of $24.5 million were used to repay in full all amounts outstanding under the previous credit facility dated June 24, 2011. Borrowings under the Partnership Credit Facility are subject to the satisfaction of customary conditions, including the absence of a default. The maturity date of the Partnership Credit Agreement is October 15, 2017.

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 selected by Compressco Partners), 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 per annum 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 outstanding principal under the Partnership Credit Agreement, Compressco Partners is required to pay a commitment fee, in respect of the unutilized commitments thereunder, of 0.375% per annum, paid quarterly in arrears. Compressco Partners is also required to pay a customary 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 4.0 to 1.0 as of the last day of any fiscal quarter, calculated on a trailing four quarters basis. 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 and subordinated units, but only if there is no default or event of default under the facility.

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).

Notes to Financial Statements [Abstract]

Basis of Presentation and 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 associated products and services, frac water management, after-frac flow back, production well testing, offshore rig cooling, compression-based production enhancement, and selected offshore services including well plugging and abandonment, decommissioning, and diving. We also have a limited domestic oil and gas production business. We were incorporated in Delaware in 1981 and are composed of five reporting segments organized into three divisions – Fluids, Production Enhancement, and Offshore. 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, which 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, 2012.

Beginning with the three month period ended September 30, 2013, certain ad valorem tax expenses for operating equipment of our Compressco segment have been classified as cost of revenues instead of being included in general and administrative expense as reported in prior periods. Prior period amounts have been reclassified to conform to the current year period's presentation. The amount of such reclassification is $0.7 million for the six month period ended June 30, 2013, and $0.4 million and $1.2 million for the three and nine month periods ended September 30, 2012, respectively. This reclassification had no effect on net income for any of the periods presented.

Certain other 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, 2013, consists primarily of escrowed cash associated with our July 2011 purchase of a heavy lift derrick barge. The escrowed cash will be released to the sellers or us 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, 2013, and December 31, 2012, are as follows: 

	September 30, 2013		December 31, 2012
	(In Thousands)
Finished goods	$	64,756	$	72,312
Raw materials	4,269		5,396
Parts and supplies	22,576		24,497
Work in progress	724		836
Total inventories	$	92,325	$	103,041

Finished goods inventories include newly manufactured clear brine fluids as well as recycled brines that are repurchased from certain 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   September 30,		Nine Months Ended   September 30,
	2013	2012	2013	2012
	(In Thousands)
Number of weighted average common shares outstanding	78,030	77,329	77,867	77,226
Assumed exercise of stock awards	933	1,609	852	1,514
Average diluted shares outstanding	78,963	78,938	78,719	78,740

In applying the treasury stock method to determine the dilutive effect of the stock options outstanding during the first nine months of 2013, we used the average market price of our common stock of $10.07. For thethree and nine months ended September 30, 2013, the average diluted shares outstanding excludes the impact of 1,571,777 and2,241,490outstanding 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 three and nine months ended September 30, 2012, the average diluted shares outstanding excludes the impact of 2,144,779and 2,054,303outstanding 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 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.

Repair Costs and Insurance Recoveries

During December 2010,we initiated legal proceedings against one of Maritech’sinsuranceunderwriters thathaddisputedthat certainhurricane damage relatedcosts incurred or to be incurred qualifiedas covered costs pursuant toMaritech’s windstorminsurancepolicies. In February 2013, we entered into a settlement agreement with the underwriter whereby we received $7.6 million, a portion of which was credited to operating expenses during the nine months ended September 30, 2013.

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 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 could 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 for 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 values of our long-term Senior Notes at September 30, 2013, and December 31, 2012, were approximately $323.2 million and $327.4 million, respectively, compared to a carrying amount of $305.0 million, as current rates onthose dates were more favorable than the stated interest rates on the Senior Notes. We calculate the fair value of our Senior Notes internally, using current market conditions and average cost of debt (a level 2 fair value measurement). The fair values of the liability for the OPTIMA contingent purchase price consideration at September 30, 2013, and December 31, 2012, were approximately $0.6 million and $2.7 million, respectively. We calculate the fair value of the liability for our contingent purchase price consideration obligation in accordance with the OPTIMA share purchase agreement based upon the actual and anticipated earnings of our OPTIMA operations (a level 3 fair value measurement).

New Accounting Pronouncements

In June 2011, theFinancial Accounting Standards Board (FASB) published Accounting Standards Update (ASU) 2011-05, “Comprehensive Income (Topic 220), Presentation of Comprehensive Income” (ASU 2011-05), with the stated 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 eliminated the option to present components of other comprehensive income as part of the statement of changes in stockholders’ equity. The ASU2011-05amendments 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 ASU2011-05amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2011, and the amendments are applied retrospectively. In December 2011, with the issuance of ASU 2011-12, “Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05,” the FASB announced that it has deferred certain aspects of ASU 2011-05. In February 2013, the FASB issued ASU 2013-2, “Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income,” with the stated objective of improving the reporting of reclassifications out of accumulated other comprehensive income. The amendments in ASU2013-2are effective during interim and annual periods beginning after December 31,2012. The adoption of ASU 2011-05, 2011-12 and 2013-2regarding comprehensive income have not had a significant impact on the accounting or disclosures in our financial statements. 

In December 2011, the FASB published ASU 2011-11, “Balance Sheet (Topic 210), Disclosures about Offsetting Assets and Liabilities” (ASU 2011-11), which requires an entity to disclose the nature of its rights of setoff and related arrangements associated with its financial instruments and derivative instruments. The objective of ASU 2011-11 is to make financial statements that are prepared under U.S. generally accepted accounting principles more comparable to those prepared under International Financial Reporting Standards. The new disclosures will give financial statement users information about both gross and net exposures. In January 2013, the FASB published ASU 2013-01, “Balance Sheet (Topic 210), Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities” (ASU 2013-01), with the stated objective of clarifying the scope of offsetting disclosures and address any unintended consequences of ASU 2011-11. ASU 2011-11 and ASU 2013-01 are effective for interim and annual reporting periods beginning after January 1, 2013, and will be applied on a retrospective basis. The adoption ofASU 2011-11 and ASU 2013-01 did nothave a material impact on our financial condition, results of operations, or liquidity.

In July 2013, the FASB published ASU No. 2013-11,"Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists" (ASU 2013-11). The amendments in this ASU provide guidance on presentation of unrecognized tax benefits and are expected to reduce diversity in practice and better reflect the manner in which an entity would settle at the reporting date any additional income taxes that would result from the disallowance of a tax position when net operating loss carryforwards, similar tax losses, or tax credit carryforwards exist. The amendments in this ASU are effective prospectively for interim and annual periods beginning after December 15, 2013, with early adoption and retrospective application permitted. We do not expect the adoption of this standard to have a material impact on our consolidated financial statements.

Decommissioning and Other Asset Retirement Obligations

Notes to Financial Statements [Abstract]

Decommissioning and Other Asset Retirement Obligations

NOTE D – 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 properties and platforms owned by our Maritech subsidiary, including the decommissioning and debris removal costs associated with one remaining offshore platform previously destroyed by a hurricane. The amount of decommissioning liabilities recorded by Maritech is reduced by amounts allocable to joint interest owners. We also operate facilities in various U.S. and foreign locations that are used in the manufacture, storage, and sale of our products, inventories, and equipment. These facilities are a combination of owned and leased assets. We are required to take certain actions in connection with the retirement of these assets. The value of our asset retirement obligations for non-Maritech properties was approximately $8.0 million and $7.5 million as of September 30, 2013, and December 31, 2012, respectively. The changes in consolidated asset retirement obligations during the three and nine month periods ended September 30, 2013, are as follows:

	Three Months Ended   September 30, 2013			Nine Months Ended   September 30, 2013
	(In Thousands)
Beginning balance for the period, as reported	$	57,330		$	94,921
Activity in the period:
Accretion of liability	173			504
Revisions in estimated cash flows	21,538			54,404
Settlement of retirement obligations	(33,738		)	(104,526		)
Ending balance as of September 30	$	45,303		$	45,303

Revisions in estimated cash flows during the first nine months of 2013 resulted primarily from additional workincurred andanticipated to be required on Maritech’s offshore oil and gas properties. Settlements of asset retirement obligations during the three and nine month periods ended September 30, 2013, include approximately $5.3 million of obligations associated with oil and gas properties that were sold by Maritech during the period.

Notes to Financial Statements [Abstract]

Acquisitions and Dispositions

NOTE B – ACQUISITIONS AND DISPOSITIONS

Acquisition of Joint Venture Interest

In October 2013, we entered into an agreement to acquire the remaining 50% ownership interest of Ahmad Albinali & TETRA Arabia Company Ltd., a Saudi Arabian limited liability company. The closing of the transaction, which is subject to customary approvals by Saudi Arabian governmental agencies as well as other conditions, is expected to occur during the fourth quarter of 2013 or early 2014. Following the closing of this transaction, the Saudi Arabian limited liability company will become a wholly owned consolidated subsidiary.

Acquisition of Optima

On March 9, 2012, we acquired 100% of the outstanding common stock of Optima Solutions Holdings Limited (OPTIMA), a provider of rig cooling services and associated products that suppress heat generated by high- rate flaring of hydrocarbons during offshore well test operations. The acquisition of OPTIMA, which is based in Aberdeen, Scotland, enables our Production Testing segment to provide its customers with a broader range of production testing and associated services and expands the segment’s presence in many significant global markets. Including the impact of additional working capital received and other adjustments to the purchase price, we paid 41.2 million pounds sterling (approximately $65.0 million equivalent) in cash as the purchase price for the OPTIMA stock at closing and may pay up to an additional 4 million pounds sterling in contingent consideration, depending on a defined measure of earnings for OPTIMA over each of the two years subsequent to the closing.

We allocated the purchase price to the fair value of the assets and liabilities acquired, which consisted of approximately $3.0 million of net working capital; $16.8 million of property, plant, and equipment; $20.4 million of certain intangible assets; $7.2 million of deferred and other tax liabilities; $3.5 million of other liabilities associated with the contingent consideration; and $35.6 million of nondeductible goodwill. The fair value of the obligation to pay the contingent consideration was calculated based on the anticipated earnings for OPTIMA over each of the next two twelve month periods subsequent to the closing and could increase (up to 4 million pounds sterling) or decrease (to zero) depending on OPTIMA’s actual and expected earnings going forward. Increases or decreases in the value of the anticipated contingent consideration liability due to changes in the amounts paid or expected to be paid will be charged or credited to earnings in the period in which such changes occur. Subsequent to the acquisition, the liability associated with the contingent consideration was adjusted downward by approximately $1.8 million (approximately $0.7 million of which was adjusted during the nine months ended September 30, 2013), and this amount was credited to earnings. The $35.6 million of goodwill recorded to our Production Testing segment as a result of the OPTIMA acquisition is supported by the expected strategic benefits discussed above to be generated from the acquisition. For the nine month period ended September 30, 2012, our revenues, depreciation and amortization, and pretax earnings included $15.1 million, $3.1 million, and $3.6 million, respectively, associated with the acquired operations of OPTIMA after the closing in March 2012. Transaction costs associated with the acquisition of approximately $1.3 million were also charged to general and administrative expense during the nine month period ended September 30, 2012.

Acquisition of ERS

On April 23, 2012, we acquired the assets and operations of Eastern Reservoir Services (ERS), a division of Patterson-UTI Energy, Inc., for a cash purchase price of $42.5 million. ERS is a provider of production testing and after-frac flow back services to oil and gas operators in the Appalachian and U.S. Rocky Mountain regions, and the acquisition represented a strategic geographic expansion of our Production Testing segment operations, allowing it to serve customers in additional basins in the U.S.

We allocated the purchase price to the fair value of the assets acquired, which consisted of approximately $18.5 million of property, plant, and equipment, approximately $3.4 million of certain intangible assets, and approximately $20.6 million of nondeductible goodwill. The $20.6 million of goodwill recorded to our Production Testing segment as a result of the ERS acquisition is supported by the strategic benefits discussed above to be generated from the acquisition. For the nine month period ended September 30, 2012, our revenues, depreciation and amortization, and pretax earnings included $16.0 million, $1.8 million, and $4.7 million, respectively, associated with the acquired operations of ERS after the closing in April 2012. In addition to the above impact on our results of operations, transaction costs associated with the ERS acquisition of approximately $0.5 million were also charged to general and administrative expense during the nine month period ended September 30, 2012.

Acquisition of Greywolf

On July 31, 2012, we acquired the assets and operations of Greywolf Production Systems Inc. and GPS Ltd. (together, Greywolf) for a cash purchase price of approximately $55.5 million. Greywolf is a provider of production testing and after-frac flow back services to oil and gas operators in western Canada and the U.S. Williston Basin (including the Bakken formation) and the Niobrara Shale formation of the U.S. Rocky Mountain region. This acquisition represented an additional strategic geographic expansion of our Production Testing segment operations.

We allocated the purchase price to the fair value of the assets acquired, which consisted of approximately $17.7 million of property, plant, and equipment, approximately $3.5 million of certain intangible assets, and approximately $34.3 million of nondeductible goodwill. The $34.3 million of goodwill recorded to our Production Testing segment as a result of the Greywolf acquisition is supported by the strategic benefits discussed above to be generated from the acquisition. For the nine month period ended September 30, 2012, our revenues, depreciation and amortization, and pretax earnings included $5.9 million, $0.4 million, and $1.2 million, respectively, associated with the acquired operations of Greywolf after the closing in July 2012. In addition to the above impact on our results of operations, transaction costs associated with the Greywolf acquisition of approximately $0.7 million were also charged to general and administrative expense during the nine month period ended September 30, 2012.

Pro Forma Financial Information

The pro forma information presented below has been prepared to give effect to the acquisitions of OPTIMA, ERS, and Greywolf as if they had occurred at the beginning of the periods presented and include the impact from the allocation of the purchase price on depreciation and amortization. The pro forma information is presented for illustrative purposes only and is based on estimates and assumptions we deemed appropriate.

Basis of Presentation and Significant Accounting Policies (Policies)

9 Months Ended

Sep. 30, 2013

Policy Text Block [Abstract]

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, which 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, 2012.

Reclassifications policy

Beginning with the three month period ended September 30, 2013, certain ad valorem tax expenses for operating equipment of our Compressco segment have been classified as cost of revenues instead of being included in general and administrative expense as reported in prior periods. Prior period amounts have been reclassified to conform to the current year period's presentation. The amount of such reclassification is $0.7 million for the six month period ended June 30, 2013, and $0.4 million and $1.2 million for the three and nine month periods ended September 30, 2012, respectively. This reclassification had no effect on net income for any of the periods presented.

Certain other 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 and 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, 2013, consists primarily of escrowed cash associated with our July 2011 purchase of a heavy lift derrick barge. The escrowed cash will be released to the sellers or us 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, 2013, and December 31, 2012, are as follows: 

	September 30, 2013		December 31, 2012
	(In Thousands)
Finished goods	$	64,756	$	72,312
Raw materials	4,269		5,396
Parts and supplies	22,576		24,497
Work in progress	724		836
Total inventories	$	92,325	$	103,041

Finished goods inventories include newly manufactured clear brine fluids as well as recycled brines that are repurchased from certain 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   September 30,		Nine Months Ended   September 30,
	2013	2012	2013	2012
	(In Thousands)
Number of weighted average common shares outstanding	78,030	77,329	77,867	77,226
Assumed exercise of stock awards	933	1,609	852	1,514
Average diluted shares outstanding	78,963	78,938	78,719	78,740

In applying the treasury stock method to determine the dilutive effect of the stock options outstanding during the first nine months of 2013, we used the average market price of our common stock of $10.07. For thethree and nine months ended September 30, 2013, the average diluted shares outstanding excludes the impact of 1,571,777 and2,241,490outstanding 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 three and nine months ended September 30, 2012, the average diluted shares outstanding excludes the impact of 2,144,779and 2,054,303outstanding 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 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.

Repair costs and insurance recoveries policy

Repair Costs and Insurance Recoveries

During December 2010,we initiated legal proceedings against one of Maritech’sinsuranceunderwriters thathaddisputedthat certainhurricane damage relatedcosts incurred or to be incurred qualifiedas covered costs pursuant toMaritech’s windstorminsurancepolicies. In February 2013, we entered into a settlement agreement with the underwriter whereby we received $7.6 million, a portion of which was credited to operating expenses during the nine months ended September 30, 2013.

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 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 could 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 for 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 values of our long-term Senior Notes at September 30, 2013, and December 31, 2012, were approximately $323.2 million and $327.4 million, respectively, compared to a carrying amount of $305.0 million, as current rates onthose dates were more favorable than the stated interest rates on the Senior Notes. We calculate the fair value of our Senior Notes internally, using current market conditions and average cost of debt (a level 2 fair value measurement). The fair values of the liability for the OPTIMA contingent purchase price consideration at September 30, 2013, and December 31, 2012, were approximately $0.6 million and $2.7 million, respectively. We calculate the fair value of the liability for our contingent purchase price consideration obligation in accordance with the OPTIMA share purchase agreement based upon the actual and anticipated earnings of our OPTIMA operations (a level 3 fair value measurement).

New Accounting Pronouncements policy

New Accounting Pronouncements

In June 2011, theFinancial Accounting Standards Board (FASB) published Accounting Standards Update (ASU) 2011-05, “Comprehensive Income (Topic 220), Presentation of Comprehensive Income” (ASU 2011-05), with the stated 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 eliminated the option to present components of other comprehensive income as part of the statement of changes in stockholders’ equity. The ASU2011-05amendments 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 ASU2011-05amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2011, and the amendments are applied retrospectively. In December 2011, with the issuance of ASU 2011-12, “Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05,” the FASB announced that it has deferred certain aspects of ASU 2011-05. In February 2013, the FASB issued ASU 2013-2, “Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income,” with the stated objective of improving the reporting of reclassifications out of accumulated other comprehensive income. The amendments in ASU2013-2are effective during interim and annual periods beginning after December 31,2012. The adoption of ASU 2011-05, 2011-12 and 2013-2regarding comprehensive income have not had a significant impact on the accounting or disclosures in our financial statements. 

In December 2011, the FASB published ASU 2011-11, “Balance Sheet (Topic 210), Disclosures about Offsetting Assets and Liabilities” (ASU 2011-11), which requires an entity to disclose the nature of its rights of setoff and related arrangements associated with its financial instruments and derivative instruments. The objective of ASU 2011-11 is to make financial statements that are prepared under U.S. generally accepted accounting principles more comparable to those prepared under International Financial Reporting Standards. The new disclosures will give financial statement users information about both gross and net exposures. In January 2013, the FASB published ASU 2013-01, “Balance Sheet (Topic 210), Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities” (ASU 2013-01), with the stated objective of clarifying the scope of offsetting disclosures and address any unintended consequences of ASU 2011-11. ASU 2011-11 and ASU 2013-01 are effective for interim and annual reporting periods beginning after January 1, 2013, and will be applied on a retrospective basis. The adoption ofASU 2011-11 and ASU 2013-01 did nothave a material impact on our financial condition, results of operations, or liquidity.

In July 2013, the FASB published ASU No. 2013-11,"Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists" (ASU 2013-11). The amendments in this ASU provide guidance on presentation of unrecognized tax benefits and are expected to reduce diversity in practice and better reflect the manner in which an entity would settle at the reporting date any additional income taxes that would result from the disallowance of a tax position when net operating loss carryforwards, similar tax losses, or tax credit carryforwards exist. The amendments in this ASU are effective prospectively for interim and annual periods beginning after December 15, 2013, with early adoption and retrospective application permitted. We do not expect the adoption of this standard to have a material impact on our consolidated financial statements.

Hedge Contracts

Notes to Financial Statements [Abstract]

Hedge Contracts

NOTE E – MARKET RISKS AND DERIVATIVEANDHEDGE 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, 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. Our financial risk management activities may at times involve, among other measures, the use of derivative financial instruments, such as swap and collaragreements, to hedge the impact of market price risk exposures. For hedge contracts qualifying for hedge accounting treatment, we formally document the 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.

In July 2012, we borrowed 10.0 million euros (approximately $13.5 million equivalent as of September 30, 2013) and designated the borrowing as a hedge of our net investment in our European operations. Changes in the foreigncurrency exchange rate have resulted in a cumulative change to the cumulative translation adjustment account of $0.9 million, net of taxes, at September 30, 2013, including a change of $0.3 million, net of taxes, during the nine months ended September 30, 2013, with no ineffectiveness recorded.

In October 2013, we and Compressco Partners each entered into foreign currency forward sale derivative contracts as part of a program designed to mitigate the currency exchange rate risk exposure on selected transactions for our Mexico subsidiaries. We entered into an approximately $10.5 million equivalent nominal value sale of U.S. dollars in November 2013, and Compressco Partners entered into an approximately $6.1 million equivalent nominal value sale of Mexican pesos in November 2013, at fixed exchange rates. Under this program, we and Compressco Partners may enter into similar derivative contracts from time to time. Although contracts pursuant to this program will serve as an economic hedge of the cash flow of our currency exchange risk exposure, they will not be formally designated as hedge contracts or qualify for hedge accounting treatment. Accordingly, any change in the fair value of these derivative instruments during a period will be included in the determination of earnings for that period.

Industry Segments

NOTE H – INDUSTRY SEGMENTS

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

Our Fluids Division manufactures and markets clear brine fluids, additives, and 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 or purchased from third-party suppliers to a variety of markets outside the energy industry.The Fluids Division also provides domestic onshore oil and gas operators with comprehensive frac water management services.

Our Production Enhancement Division consists of two operating segments: Production Testing and Compressco. The Production Testing segment provides after-frac flow back, production well testing, offshore rig cooling, and other associated services in many of the major oil and gas basins in the United States, Mexico, and Canada, as well as in certain basins in certain regions in South America, Africa, Europe, the Middle East, and Australia.

The Compressco segment provides compression-based production enhancement services, which are used in both conventional wellhead compression applications and unconventional compression applications, and in certain circumstances, well monitoring and sand separation services. Compressco provides these services throughout many of the onshore oil and gas producing regions of the United States, as well as certain basins in Mexico, Canada, and certain countries in South America, Eastern Europe, and the Asia-Pacific region. Beginning June 20, 2011, following the initial public offering of Compressco Partners, we allocate and charge certain corporate and divisional direct and indirect administrative costs to Compressco Partners.

Our Offshore Division consists of two operating segments: Offshore Services and Maritech. The Offshore Services segment provides (1) downhole and subsea oil and gas well plugging and abandonment services, (2) decommissioning and certain construction services utilizing heavy lift barges and various cutting technologies with regard to offshore oil and gas production platforms and pipelines, and (3) conventional and saturated air diving services.

The Maritech segment is an oil and gas production operation. During 2011 and the first quarter of 2012, Maritech sold substantially all of its oil and gas producing property interests. Maritech’s operations consist primarily of the ongoing abandonment and decommissioning associated with its remaining offshore wells, facilities, and production platforms. Maritech intends to acquire a significant portion of the services necessary to abandon and decommission these properties from the Offshore Division’s Offshore Services segment.

We generally evaluate the performance of and allocate resources to our segments based on profit or loss from their 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:
