NOTES TO THE UNAUDITED CONSOLIDATED INTERIM FINANCIAL STATEMENTS

1. BASIS OF PRESENTATION

The accompanying unaudited consolidated financial statements include the accounts of Core Laboratories N.V. and its subsidiaries for which we have a controlling voting interest and/or a controlling financial interest. These financial statements have been prepared in accordance with United States ("U.S.") generally accepted accounting principles ("GAAP") for interim financial information using the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, these financial statements do not include all of the information and footnote disclosures required by GAAP for complete financial statements.

Core Laboratories N.V. uses the equity method of accounting for all investments in which it has less than a majority interest and over which it does not exercise control. Minority interest has been recorded to reflect outside ownership attributable to consolidated subsidiaries that are less than 100% owned. In the opinion of management, all adjustments considered necessary for a fair presentation have been included in these financial statements. Furthermore, the operating results presented for the three and six month periods ended June 30, 2007 may not necessarily be indicative of the results that may be expected for the year ending December 31, 2007.

Core Laboratories N.V.'s balance sheet information for the year ended December 31, 2006 was derived from the 2006 audited consolidated financial statements but does not include all disclosures in accordance with GAAP.

References to "Core Lab", "we", "our", and similar phrases are used throughout this Quarterly Report on Form 10-Q and relate collectively to Core Laboratories N.V. and its consolidated subsidiaries.

These financial statements should be read in conjunction with the financial statements and the summary of significant accounting policies and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2006.

2. INVENTORIES

Inventories consist of the following (in thousands):

	June 30,	December 31,
	2007	2006
	(Unaudited)
Finished goods	$   23,878	$     22,930
Parts and materials	6,644	6,031
Work in progress	1,426	1,238
Total inventories	$   31,948	$     30,199

We include freight costs incurred for shipping inventory to customers in the Cost of Sales line of the Consolidated Statement of Operations.

3. GOODWILL AND INTANGIBLES

We account for intangible assets with indefinite lives, including goodwill, in accordance with Statement of Financial Accounting Standards No. 142, "Goodwill and Other Intangible Assets", which requires us to evaluate these assets for impairment annually, or more frequently if an indication of impairment has occurred. Based upon our most recent evaluation, management determined that goodwill was not impaired. We amortize intangible assets with a defined term on a straight-line basis over their respective useful lives. There were no significant changes related to our intangible assets for the six months ended June 30, 2007. The composition of goodwill by business segment at June 30, 2007 is consistent with the amounts disclosed in our Annual Report on Form 10-K as of December 31, 2006.

4. DEBT AND CAPITAL LEASE OBLIGATIONS

Debt is summarized in the following table (in thousands):

	June 30,	December 31,
	2007	2006
	(Unaudited)
Senior Exchangeable Notes	$     300,000	$   300,000
Capital lease obligations	8	10
Other indebtedness	674	2,754
Total debt and capital leases obligations	300,682	302,764
Less - short-term debt included in other indebtedness	674	2,654
Less - current maturities of long-term debt and capital lease obligations	6	108
Long-term debt and capital lease obligations	$     300,002	$    300,002

In November 2006, Core Laboratories LP, a wholly owned subsidiary of Core Laboratories N.V., issued $300 million aggregate principal amount of Senior Exchangeable Notes due 2011 (the "Notes") to qualified institutional buyers. The Notes bear interest at a rate of 0.25% per year and are fully and unconditionally guaranteed by Core Laboratories N.V. These notes are exchangeable into shares of Core Laboratories N.V. under certain circumstances at an initial conversion rate of 10.5533 per $1,000 principal amount of notes. Upon exchange, holders will receive cash up to the principal amount, and any excess exchange value will be delivered in Core Laboratories N.V. common shares. On December 22, 2006 we filed a registration statement on Form S-3, which became effective pursuant to the Securities Act of 1933, as amended; to register the resale of the notes and shares received in exchange for the notes.

We maintain a revolving credit facility (the "Credit Facility") that allows for an aggregate borrowing capacity of $100.0 million. As amended, this facility provides an option to increase the commitment under the Credit Facility to $150.0 million, if certain conditions are met. The Credit Facility bears interest at variable rates from LIBOR plus 0.5% to a maximum of LIBOR plus 1.125%. The outstanding balance under the Credit Facility matures when it is due in December 2010 and only requires bi-annual interest payments until maturity. These interest payments are based on the interest period selected. Our available capacity is reduced by outstanding unsecured letters of credit and performance guarantees and bonds totaling $7.6 million at June 30, 2007 related to certain projects in progress. Our available borrowing capacity under the Credit Facility at June 30, 2007 was $92.4 million.

5. PENSIONS AND OTHER POST-RETIREMENT BENEFITS

We provide a noncontributory defined benefit pension plan covering substantially all of our Dutch employees, payouts under which are determined based on years of service and final pay or career average pay, depending on when the employee began participating. Employees are immediately vested in the benefits earned. We fund the future obligations of this plan by purchasing investment contracts from a large national insurance company. We make annual premium payments, based on each employee's age and current salary, to the insurance company.

The following table summarizes the components of the net periodic pension cost under this plan for the three and six month periods ended June 30, 2007 and 2006 (in thousands):

	Three Months Ended June 30,		Six Months Ended June 30,
	2007	2006	2007	2006
	(Unaudited)		(Unaudited)
Service cost	$     298	$     322	$     589	$     610
Interest cost	274	242	540	457
Expected return on plan assets	(250)	(234)	(493)	(443)
Unrecognized pension obligation, net	18	38	36	71
Net periodic pension cost	$     340	$     368	$     672	$     695

6. COMMITMENTS AND CONTINGENCIES

Legal Proceedings

From time to time, we may be subject to legal proceedings and claims that arise in the ordinary course of business. We believe that the resolution of all litigation currently pending or threatened against Core Lab or any of its subsidiaries should not have a material adverse effect on its consolidated financial condition, results of operations or liquidity; however, because of the inherent uncertainty of litigation, we cannot provide assurance that the resolution of any particular claim or proceeding to which Core Lab or any of its subsidiaries is a party will not have a material adverse effect on its consolidated results of operations or liquidity for the period in which that resolution occurs.

7. SHAREHOLDERS' EQUITY

During the three months ended June 30, 2007, we repurchased 170,800 of our common shares for $16.8 million, at an average price of $98.24 per share. During the quarter, rights to 36,400 shares valued at $3.4 million, or $92.34 were surrendered to the Company pursuant to the terms of a stock-based compensation plan, in settlement by the participants of personal tax burdens that may result from the issuance of common shares under this plan.

During the six months ended June 30, 2007, we repurchased 914,450 of our common shares for $75.4 million, at an average price of $82.46 per share which included rights to 602,050 shares valued at $48.3 million, or $80.29 per share, that were surrendered to the Company pursuant to the terms of a stock-based compensation plan, in consideration of the exercise price of their stock options and their personal tax burdens that may result from the issuance of common shares under this plan.

For the three and six months ended June 30, 2007, we issued 24,216 and 1,329,608 of our common shares associated with stock option exercises for which we received proceeds of approximately $0.3 million and $17.2 million.

At our Annual Shareholders' Meeting on April 2, 2007 (the "Meeting"), our shareholders approved the cancellation of 3,127,040 treasury shares we had repurchased or otherwise acquired prior to the date of the Meeting. These 3,127,040 treasury shares were cancelled in April 2007 at historical cost, totaling $233.5 million, or $74.73 per share, resulting in a decrease in treasury shares and a corresponding decrease in additional paid-in-capital, retained earnings and common shares. Our shareholders also approved the extension of the authority of our Management Board to repurchase up to 10% of the Company's outstanding share capital up through October 2, 2008.

Comprehensive Income

The components of other comprehensive income consisted of the following (in thousands):

	Three months ended	Six months ended
	June 30, 2007	June 30, 2007
	(Unaudited)	(Unaudited)
Net income	$ 28,803	$   54,065
Realization of pension obligation	18	36
Total comprehensive income	$ 28,821	$   54,101

Accumulated Other Comprehensive Income consisted of the following (in thousands):

	June 30,	December 31,
	2007	2006
	(Unaudited)

Pension obligation - unrecognized net actuarial loss	745	745
Total accumulated other comprehensive income	$     2,036	$    2,072

8. EARNINGS PER SHARE

We compute basic earnings per common share by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted earnings per common and potential common shares include additional shares in the weighted average share calculations associated with the incremental effect of dilutive employee stock options, restricted stock awards and contingently issuable shares, as determined using the treasury stock method. The following table summarizes the calculation of weighted average common shares outstanding used in the computation of diluted earnings per share (in thousands):

	Three Months Ended June 30,		Six Months Ended June 30,
	2007	2006	2007	2006
	(Unaudited)		(Unaudited)
Weighted average basic common shares outstanding	23,940	25,560	23,686	25,676
Effect of dilutive securities:
Stock options	276	1,400	469	1,538
Contingent shares	84	151	103	140
Restricted stock and other	113	80	109	124
Weighted average diluted common and potential common shares outstanding	24,413	27,191	24,367	27,478

In 2006, we sold warrants that give the holders the right to acquire approximately 3.2 million of our common shares at a strike price of $127.56 per share.  These warrants could have a dilutive impact on our earnings per share if the share price exceeds the strike price of the warrants. 

9. OTHER INCOME

The components of other income, net, were as follows (in thousands):

	Three Months Ended June 30,		Six Months Ended June 30,
	2007	2006	2007	2006

Total other income, net	$  (1,473)	$  (1,546)	$  (2,336)	$  (3,416)

In 2005, a building at our manufacturing plant in Godley, Texas, was damaged by fire, resulting in the loss of the building, some inventory, as well as other business equipment and supplies. We filed a claim for business interruption costs and the final settlement was reached in the first quarter of 2006, which resulted in a gain of $0.5 million.

Foreign exchange gains by currency are summarized in the following table (in thousands):

Total gain	$    (493)	$   (1,102)	$    (475)	$   (1,462)

10. INCOME TAXES

We file an income tax return in the U.S. federal jurisdiction, various states and foreign jurisdictions. We are currently undergoing multiple examinations in various jurisdictions, and the years 1998 through 2006 remain open for examination in various tax jurisdictions in which we operate.

We adopted the provisions of FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes-An Interpretation of FASB Statement No. 109, Accounting for Income Taxes ("FIN 48"), on January 1, 2007. FIN 48 clarifies the accounting for uncertainty in income taxes recognized in financial statements and requires the impact of a tax position to be recognized in the financial statements if that position is more likely than not of being sustained by the taxing authority. As a result of the implementation of FIN 48, we recognized approximately a $3.3 million increase in the liability for unrecognized tax benefits, which was accounted for as a reduction to the January 1, 2007 balance of retained earnings. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows (in thousands):

	2007
	(Unaudited)
Unrecognized tax benefits at January 1,	$   13,064
Tax positions, current period	231
Tax positions, prior period	1,942
Settlements with taxing authorities	-
Lapse of applicable statute of limitations	-
Unrecognized tax benefits at June 30,	$   15,237

The total amount of unrecognized tax benefits at June 30, 2007, if recognized, would affect our effective tax rate.

Our policy is to record accrued interest and penalties on uncertain tax positions, net of any tax effect, as part of total tax expense for the period. The corresponding liability is carried along with the tax exposure as a non-current payable in "other long-term liabilities". We had approximately $3.2 million accrued for the payment of interest and penalties as of January 1, 2007. We expect the requirements of FIN 48 will add volatility to our effective tax rate, and therefore our expected income tax expense, in future periods.

During the three and six month period ended June 30, 2007, we recognized tax benefits of $7.5 and $10.1 million, respectively, related to tax deductions in excess of book expense for stock-based compensation awards.  These tax benefits are recorded to additional paid-in capital to the extent deductions reduce current taxable income.

11. SEGMENT REPORTING

Our business units have been aggregated into three complementary segments, which provide products and services for improving reservoir performance and increasing oil and gas recovery from new and existing fields.

*	Reservoir Description: Encompasses the characterization of petroleum reservoir rock, fluid and gas samples. We provide analytical and field services to characterize properties of crude oil and petroleum products to the oil and gas industry.
*	Production Enhancement: Includes products and services relating to reservoir well completions, perforations, stimulations and production. We provide integrated services to evaluate the effectiveness of well completions and to develop solutions aimed at increasing the effectiveness of enhanced oil recovery projects.
*	Reservoir Management: Combines and integrates information from reservoir description and production enhancement services to increase production and improve recovery of oil and gas from our clients' reservoirs.

Segment Analysis

We manage each of our business segments separately to reflect the different services and technologies provided and required by each segment. We use the same accounting policies to account for our business segments as those used to prepare our Consolidated Balance Sheets and Consolidated Statements of Operations. We evaluate the performance of our business segments on the basis of operating income.

Summarized financial information related to our business segments is shown in the following tables (in thousands):

13. RECENT ACCOUNTING PRONOUNCEMENTS

In September 2006, the Financial Accounting Standards Board ("FASB") issued SFAS No. 157, Fair Value Measurements ("FAS 157"). FAS No. 157 defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles and expands disclosures about fair value measurements. FAS No. 157 does not require any new fair value measurements, rather, its application will be made pursuant to other accounting pronouncements that require or permit fair value measurements. FAS No. 157 is effective for fiscal years beginning after November 15, 2007, and interim periods within those years. The provisions of FAS No. 157 are to be applied prospectively upon adoption, except for limited specified exceptions. We do not expect the adoption of FAS No. 157 to have a material impact on our financial position, results of operations or cash flows.

In February 2007, the FASB issued SFAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities - Including an Amendment of FASB Statement No. 115 ("FAS 159"). FAS 159 permits companies to measure eligible financial instruments and certain other items at fair value that are currently not required to be measured at fair value. FAS 159 will become effective for financial statements issued for fiscal years beginning after November 15, 2007, with early adoption permitted. We are currently evaluating FAS 159 and any potential impact on our financial statements, however we do not expect this pronouncement to have a material impact on our financial position or results of operations.

Cautionary Statement Regarding Forward Looking Statements

This quarterly report contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. Certain of the statements contained in this Management's Discussion and Analysis of Financial Condition and Results of Operations section, including those under the headings "Outlook" and "Liquidity and Capital Resources", and in other parts of this 10-Q, are forward looking. In addition, from time to time, we may publish forward-looking statements relating to such matters as anticipated financial performance, business prospects, technological developments, new products, research and development activities and similar matters. Forward-looking statements can be identified by the use of forward-looking terminology such as "may", "will", "believe", "expect", "anticipate", "estimate", "continue", or other similar words, including statements as to the intent, belief, or current expectations of our directors, officers, and management wi th respect to our future operations, performance, or positions or which contain other forward-looking information. These forward-looking statements are predictions. No assurances can be given that the future results indicated, whether expressed or implied, will be achieved. Our actual results may differ significantly from the results discussed in the forward-looking statements. While we believe that these statements are and will be accurate, a variety of factors could cause our actual results and experience to differ materially from the anticipated results or other expectations expressed in our statements. Such factors include, but are not limited to, the risks and uncertainties summarized below:

- general and economic business conditions;

- prices of oil and natural gas and industry expectations about future prices;

- foreign exchange controls and currency fluctuations;

- political stability in the countries in which we operate;

- the business opportunities (or lack thereof) that may be presented to and pursued by us;

- changes in laws or regulations; and

- the validity of the assumptions used in the design of our disclosure controls and procedures.

Should one or more of these risks or uncertainties materialize, or should any of our assumptions prove incorrect, actual results may vary in material respects from those projected in the forward-looking statements. We undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. For a more detailed discussion of some of the foregoing risks and uncertainties, see "Item 1A - Risk Factors" in our Annual Report on Form 10-K for the fiscal year ended December 31, 2006, as well as the other reports and registration statements filed by us with the SEC.

Recent Developments

On January 1, 2007, we adopted FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes-An Interpretation of FASB Statement No. 109, Accounting for Income Taxes ("FIN 48"), which was issued to create a single model to address accounting for uncertainty in tax positions. FIN 48 clarifies the accounting for income taxes, by prescribing a minimum recognition threshold a tax position is required to meet before being recognized in the financial statements. FIN 48 also provides guidance on derecognition, measurement, classification, interest and penalties, accounting in interim periods, disclosure and transition. FIN 48 became effective for fiscal years beginning after December 15, 2006. The cumulative effect of $3.3 million from adopting FIN 48 was recorded in retained earnings and other long-term liabilities.

Outlook

We have established internal earnings targets that are based on current market conditions. Based on industry surveys, we anticipate North American activity levels of our clients during 2007 to be somewhat lower than their activity levels in 2006. We also believe that the activity levels outside of North America for 2007 will continue to remain higher than activity levels for 2006.

Operating Results for the Three and Six Months Ended June 30, 2007 Compared to the Three and Six Months Ended June 30, 2006 (unaudited)

Service Revenues

Service revenues increased to $126.2 million for the second quarter of 2007, up 19% when compared to $106.4 million for the second quarter of 2006. For the six months ended June 30, 2007, service revenues increased 18% to $243.2 million compared to $205.5 million for the respective period in 2006. This increase in revenue was primarily due to the continued strength in the price of oil which is driving increased demand for oilfield activities globally. This increased activity in turn continued to create increased demand for the services we provide. In addition, we have experienced an increase in market penetration and market acceptance of recently introduced services. This has benefited our business in the Middle East, especially Qatar and Saudi Arabia, where these services will be used to increase daily natural gas and crude oil production while maximizing the ultimate hydrocarbon recoveries from the Qatari and Saudi Arabian fields.

Product Sale Revenues

Revenues associated with product sales increased to $42.2 million for the second quarter of 2006, up 25% from $33.7 million for the second quarter of 2006. For the six months ended June 30, 2007, product sale revenues increased 13% to $81.0 million compared to $71.9 million for the same period in 2006. Increased drilling activity on a global basis, but more specifically greater market penetration for our well completion products contributed to our improved results. Additionally, increased demand in Canada for our proprietary reservoir monitoring equipment significantly contributed to these improved results. During the first quarter we introduced new reservoir optimizing technologies which began to generate additional revenues that should produce higher operating margins which should also increase incremental margins.

Cost of Services

Cost of services expressed as a percentage of service revenue was 67% for the quarter ended June 30, 2007, down from 71% for the corresponding quarter in 2006. For the six-month period ending June 30, 2007, cost of services expressed as a percentage of service revenue was 68% as compared to 72% for the same period for 2006. The decline in the cost of services relative to service revenue was primarily a result of incremental margins earned on higher revenues over our relatively fixed cost structure. Incremental margins are calculated as the change in operating income divided by the change in revenues.

Cost of Sales

Cost of sales as a percentage of product sale revenues was 69% for the quarter ended June 30, 2007, which was an improvement from the 74% for the same period in 2006. For the six month period ending June 30, 2007, cost of product sales expressed as a percentage of sales revenue was 70% which was an improvement from the 73% for the same period in 2006. The decrease in cost of sales as a percentage of product sale revenues for 2007 was primarily due to growing demand for new higher margin products and continuing efforts to improve our manufacturing efficiencies.

General and Administrative Expenses

General and administrative expenses were $9.7 million for the second quarter of 2007 compared to $8.7 million for the second quarter of 2006. This increase was primarily due to an increase in salaries and incentive compensation relating to our improved performance and additional accounting services related to the conversion of our local Dutch statutory financials from Dutch GAAP to IFRS. For the six-month periods ended June 30, 2007 and 2006, general and administrative expenses decreased $1.4 million to $17.8 million from $19.2 million relating to lower compensation benefits for certain members of management recorded in the first half of 2007 compared to 2006.

Depreciation and Amortization Expense

Depreciation and amortization expense of $4.9 million for the second quarter of 2007 increased $0.8 million, from $4.1 million for the second quarter of 2006. For the six-month period ended June 30, 2007, depreciation and amortization expense was $9.5 million, an increase of $1.3 million from the June 30, 2006 due to an increase in capital expenditures the latter half of 2006.

In 2005, a building at our manufacturing plant in Godley, Texas, was damaged by fire, resulting in the loss of the building, some inventory, as well as other business equipment and supplies. We filed a claim for business interruption costs and the final settlement was reached in the first quarter of 2006, which resulted in a gain of $0.5 million.

Segment Analysis

Our operations are managed primarily in three complementary segments - Reservoir Description, Production Enhancement and Reservoir Management. The following table summarizes our results by operating segment for the three and six-month periods ended June 30, 2007 and 2006 (in thousands):

1) "Corporate and Other" represents those items that are not directly related to a particular segment

Reservoir Description

Revenues from the Reservoir Description segment increased $13.7 million, to $93.8 million in the second quarter of 2007, compared to $80.1 million in the second quarter of 2006, as a result of continued expansion of oilfield activities world-wide and North American projects related to gas-shale and Canadian oil-sands reservoirs. For the six months ended June 30, 2007 revenues increased $25.6 million, to $176.9 million from $151.3 million for the six months ended June 30, 2006. The revenue growth was driven, in part, by the increased demand for our recently introduced proprietary and patented reservoir optimization technologies and related services. These include our Pressurized Fluid Imaging Services (PFIS^TM) and our fluid characterization services in North America, Europe, Asia and Middle East. We are expanding our services, especially in the Middle East, which will be used to increase daily natural gas and crude oil production while maximizing the ultimate hydrocarbon recoveries.

Operating income in the second quarter of 2007 increased by 50% or $7.1 million to $21.4 million compared to $14.3 million for the second quarter of 2006. Operating income for the six-month period ended June 30, 2007 increased by 63% or $14.8 million to $38.2 million. Increases in operating income were primarily due to incremental margins earned from higher sales over our relatively fixed cost structure and the introduction and acceptance of recently introduced reservoir optimization services. Operating margins for the quarter and six months ended June 30, 2007 were 23% and 22%, respectively compared to 18% and 15% for the same periods in 2006, respectively. Our customers continue to shift from lower margin projects to those projects having a higher content of Core's newer services and technologies, which produced incremental margins of 58% for the six-months, on higher revenues during the period. Incremental margins are calculated as the change in operating income divided by the change in revenues. < /P>

Production Enhancement

Revenues from the Production Enhancement segment increased $9.2 million to $60.8 million in the second quarter of 2007 as compared to $51.6 million in the second quarter in 2006, and revenues increased $11.9 million to $119.6 million for the six months ended June 30, 2007 as compared to $107.7 million for the same period in 2006. This increase was primarily the result of continued improvement in market penetration of our well perforating and completion products and stimulation diagnostic services, overall expansion in global drilling activities, and continued improvements in the international expansion of our technologies.

Operating income in the second quarter of 2007 increased by 28% or $3.5 million to $16.2 million from $12.7 million for the second quarter of 2006. Operating margins increased to 27% in the second quarter of 2007 compared to 25% for the same period in 2006. For the six months ended June 30, 2007, operating income increased to $32.3 million, an increase of 26% over the same period in 2006. These margin improvements were primarily due to increased sales of higher-margin services and products including new enhanced recovery technology, such as SpectraScan™, SpectraStim™, Completion Profiler™ and our SuperHERO™ perforating charges and gun systems, as well as improved manufacturing efficiencies. Additionally, the demand for our technology in fracture diagnostics continues to increase as drilling activity increases in unconventional reservoirs.

Reservoir Management

Revenues from the Reservoir Management segment increased $5.6 million, or 68%, in the second quarter of 2007 as compared to the second quarter of 2006. Revenues for the six-month period ended June 30, 2007 were $27.6 million, an increase of 51% from $18.3 million from the same period in 2006. The improvement was a result of higher revenue from our multi-client regional reservoir optimization projects for both North America and international studies, especially studies pertaining to unconventional gas reservoirs and sales of our proprietary reservoir monitoring products for oil-sands in Canada.

Operating income in the second quarter of 2007 increased 152% to $4.1 million from $1.6 million for the second quarter of 2006. Operating margins increased to 30% in the second quarter of 2007 compared to 20% for the same period in 2006. For the six-month period ended June 30, 2007, operating income was $7.8 million with operating margins of 28%, as compared to operating income of $4.6 million and operating margins of 25% from the same period in 2006. The increase was primarily due to the continued expansion of the multi-client regional reservoir study sales in the U.S. and expansion of studies being performed in Libya, along with product sales to the oil-sands projects in Canada.

Liquidity and Capital Resources

General

We have historically financed our activities through cash on hand, cash flows from operations, bank credit facilities, or the issuance of debt and equity financing.

We utilize the non-GAAP financial measure of free cash flow to evaluate our cash flows and results of operations. Free cash flow is defined as net cash provided by operating activities (which is the most directly comparable GAAP measure) less capital expenditures. Management believes that free cash flow provides useful information to investors as it represents the cash, in excess of capital expenditures, available to operate the business and fund non-discretionary obligations. Free cash flow is not a measure of operating performance under GAAP, and should not be considered in isolation nor construed as an alternative to operating profit, net income (loss) or cash flows from operating, investing or financing activities, each as determined in accordance with GAAP. Moreover, since free cash flow is not a measure determined in accordance with GAAP and thus is susceptible to varying interpretations and calculations, free cash flow as presented, may not be comparable to similarly titled measures presented by other companies. The following table reconciles this non-GAAP financial measure to the most directly comparable measure calculated and presented in accordance with U.S. GAAP for the three month period ended June 30, 2007 and 2006 (in thousands):

	Six Months Ended June 30,
	2007	2006
Free cash flow calculation:	(unaudited)
Net cash provided by operating activities	$    59,722	$    51,450
Less: capital expenditures	8,552	9,858
Free cash flow	$    51,170	$    41,592

The increase in free cash flow in 2007 compared to 2006 was due to higher net income and a decrease in capital expenditures offset by a net increase in working capital, excluding cash. At June 30, 2007 and December 31, 2006, we had working capital of $148.4 million and $136.6 million, respectively.

Cash Flows

The following table summarizes cash flows for the six months ended June 30, 2007 and 2006 (in thousands):

	Six Months Ended June 30,
	2007	2006
Cash provided by/(used in):	(unaudited)
Operating activities	$    59,722	$   51,450
Investing activities	(9,256)	(8,350)
Financing activities	(50,308)	(44,694)
Net change in cash and cash equivalents	$        158	$    (1,594)

The increase in cash flows provided by operating activities was attributable to an increase in net income offset by an increase in working capital due to timing of payments. The increase in cash used in investing activities is due to larger sales proceeds received in the prior year which offset the higher capital expenditures. The cash flows used in financing activities in 2007 relates primarily to shares repurchased under our common share repurchase program, stock options issued and a tax benefit from stock-based compensation. In the first six months of 2007, we repurchased approximately 0.9 million shares for an aggregate price of $75.4 million compared to approximately 1.5 million shares for an aggregate price of $77.6 million during the six months ended June 30, 2006. In addition, we received proceeds from the exercise of stock options in the amount of $17.2 million and recognized a tax benefit of $10.1 million in 2007 and received proceeds from the exercise of stock options of $12.3 million, recog nized a tax benefit of $5.5 million and borrowings of $22.0 million in 2006.

We maintain a revolving credit facility (the "Credit Facility") that allows for an aggregate borrowing capacity of $100.0 million. As amended, this facility provides an option to increase the commitment under the Credit Facility to $150.0 million, if certain conditions are met. The Credit Facility bears interest at variable rates from LIBOR plus 0.5% to a maximum of LIBOR plus 1.125%. The outstanding balance under the Credit Facility matures when it is due in December 2010 and only requires bi-annual interest payments until maturity. These interest payments are based on the interest period selected. Our available capacity is reduced by outstanding unsecured letters of credit and performance guarantees and bonds totaling $7.6 million at June 30, 2007 related to certain projects in progress. Our available borrowing capacity under the Credit Facility at June 30, 2007 was $92.4 million.

The terms of the Credit Facility require us to meet certain financial and operational covenants. We believe that we are in compliance with all such covenants at June 30, 2007. All of our material, wholly owned subsidiaries are guarantors or co-borrowers under the Credit Facility.

Our ability to maintain and grow our operating income and cash flow depends, to a large extent, on continued investing activities. We are a Netherlands holding company and substantially all of our operations are conducted through subsidiaries. Consequently, our cash flow depends upon the ability of our subsidiaries to pay cash dividends or otherwise distribute or advance funds to us. We believe our future cash flows from operations, supplemented by our borrowing capacity and issuances of additional equity should be sufficient to fund our debt requirements, capital expenditures, working capital, and future acquisitions.

At our Annual Shareholders' Meeting on April 2, 2007 (the "Meeting"), our shareholders approved the cancellation of 3,127,040 treasury shares we had repurchased or otherwise acquired up to the date of the Meeting. These 3,127,040 treasury shares were cancelled in April 2007 at historical cost, totaling $233.5 million, or $74.73 per share, resulting in a decrease in treasury shares and a corresponding decrease in additional paid-in-capital, retained earnings and common stock. Our shareholders also approved the extension of the authority of our Management Board to repurchase up to 10% of the Company's outstanding share capital up through October 2, 2008.

Recent Accounting Pronouncements

In September 2006, the Financial Accounting Standards Board ("FASB") issued SFAS No. 157, Fair Value Measurements ("FAS 157"). FAS No. 157 defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles and expands disclosures about fair value measurements. FAS No. 157 does not require any new fair value measurements, rather, its application will be made pursuant to other accounting pronouncements that require or permit fair value measurements. FAS No. 157 is effective for fiscal years beginning after November 15, 2007, and interim periods within those years. The provisions of FAS No. 157 are to be applied prospectively upon adoption, except for limited specified exceptions. We do not expect the adoption of FAS No. 157 to have a material impact on our financial position, results of operations or cash flows.

In February 2007, the FASB issued SFAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities - Including an Amendment of FASB Statement No. 115 ("FAS 159"). FAS 159 permits companies to measure eligible financial instruments and certain other items at fair value that are currently not required to be measured at fair value. FAS 159 will become effective for financial statements issued for fiscal years beginning after November 15, 2007, with early adoption permitted. We are currently evaluating FAS 159 and any potential impact on our financial statements, however we do not expect this pronouncement to have a material impact on our financial position or results of operations.

Item 3. Quantitative and Qualitative Disclosures of Market Risk

There have been no material changes in market risk from the information provided in Item 7A. "Quantitative and Qualitative Disclosures About Market Risk" in our Annual Report on Form 10-K as of December 31, 2006.

Item 4. Controls and Procedures

A complete discussion of our controls and procedures is included in our Form 10-K for the year ended December 31, 2006.

Disclosure Controls and Procedures

Our management, under the supervision of and with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of Core Laboratories N.V.'s disclosure controls and procedures, as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), as of the end of the period covered by this report. Our disclosure controls and procedures are designed to provide reasonable assurance that the information required to be disclosed by us in our reports filed or submitted under the Exchange Act is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure and is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission. Based on such evaluation, our Chief Executive Officer and Chief Financial Offic er have concluded that our disclosure controls and procedures were effective as of June 30, 2007 at the reasonable assurance level. Our management does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent all errors and all fraud. Further, the design of disclosure controls and internal control over financial reporting must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within a company have been detected.

Changes in Internal Control Over Financial Reporting

There have not been any changes in our internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act, during our fiscal quarter ended June 30, 2007, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

At each annual shareholders' meeting subsequent to 1995, our shareholders have renewed that authorization. At our Annual Shareholders' Meeting on April 2, 2007, our shareholders approved the extension of the authority of our Management Board to repurchase up to 10% of the Company's outstanding share capital up through October 2, 2008.
