CORE LABORATORIES N.V.
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 U.S. GAAP and 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, 2008.

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. Non-controlling 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 for the periods presented have been included in these financial statements.  Furthermore, the operating results presented for the three and six months ended June 30, 2009 may not necessarily be indicative of the results that may be expected for the year ending December 31, 2009. We have performed an evaluation of subsequent events through July 23, 2009, which is the date the financial statements were issued.

Core Laboratories N.V.'s balance sheet information for the year ended December 31, 2008 was derived from the 2008 audited consolidated financial statements as revised for the recently adopted accounting principles, 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.

We include freight costs incurred for shipping inventory to customers in the Cost of Sales line of the Consolidated Statements 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, we did not identify a triggering event; therefore, we have determined that goodwill is not impaired.  We amortize intangible assets with a defined term on a straight-line basis over their respective useful lives.

There were no other significant changes relating to our intangible assets for the six months ended June 30, 2009.  The remaining composition of goodwill by business segment at June 30, 2009 is consistent with the amounts disclosed in our Annual Report on Form 10-K as of December 31, 2008.

4.  DEBT AND CAPITAL LEASE OBLIGATIONS



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

2008(Unaudited)Senior exchangeable notes

$           238,658

44,090Net senior exchangeable notes

$       201,709

$     194,568




On January 1, 2009, we adopted FASB Staff Position ("FSP") No. APB 14-1, "Accounting for Convertible Debt Instruments That May Be Settled in Cash upon Conversion (Including Partial Cash Settlement)" ("APB 14-1"). APB 14-1 specifies that issuers of such instruments should separately account for the liability and equity components in a manner that will reflect the entity's nonconvertible debt borrowing rate when interest cost is recognized in subsequent periods. The adoption of APB 14-1 on January 1, 2009 impacted the historical accounting for our Senior Exchangeable Notes ("Notes") and resulted in an increase to Additional Paid in Capital of $51.9 million and Deferred Tax Liabilities of $16.1 million with an offset to Retained Earnings of $23.9 million and a discount on the Notes of $44.1 million. The impact to net income and to diluted earnings per share was a decrease of $1.3 million and $3.9 million and $0.06 and $0.16 for the three and six months ended June 30, 2008, respectively.  The discount will be amortized into interest expense through November 2011.



In 2006, Core Laboratories LP, a wholly owned subsidiary of Core Laboratories N.V., issued $300 million aggregate principal amount of the Notes due 2011.  The Notes bear interest at a rate of 0.25% per year paid on a semi-annual basis and are fully and unconditionally guaranteed by Core Laboratories N.V. resulting in interest expense of $0.1 million and $0.2 million for the three months ended June 30, 2009 and 2008, respectively, and $0.3 million and $0.4 million for the six months ended June 30, 2009 and 2008, respectively. With the additional amortization of the discount on the Notes, the effective interest rate is 7.48% for the period ended June 30, 2009, which resulted in additional non-cash interest expense of $3.6 million and $4.2 million for the three months ended June 30, 2009 and 2008, respectively, and $7.1 million and $8.4 million for the six months ended June 30, 2009 and 2008, respectively.  The Notes are exchangeable into shares of Core Laboratories N.V. under certain circumstances at a conversion rate of $93.61 or 10.6825 per $1,000 principal amount of the 238,658 Notes outstanding at June 30, 2009.  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. The carrying value of the equity component of the Notes was $84.4 million at June 30, 2009 and December 31, 2008. At June 30, 2009, the Notes were trading at 103.0% of their face value.



As part of the issuance of the Notes, we entered into an exchangeable senior note hedge transaction in October 2006 (the "Call Option") through one of our subsidiaries with Lehman Brothers OTC Derivatives Inc. ("Lehman OTC") whereby Lehman OTC is obligated to deliver to us an amount of shares required to cover the shares issuable upon conversion of the Notes.  On October 3, 2008, Lehman OTC filed for protection under Chapter 11 of the U.S. Bankruptcy Code.  Although we may not retain the benefit of the Call Option if Lehman OTC fails to perform under the contract, we believe the impact will not be material and would not affect our income statement presentation. In addition, we do not expect Lehman OTC's default to result in a direct impact on our balance sheet as the Call Option was initially recorded as an equity transaction.  We are currently unable to ascertain whether any value would be established for our unsecured position or how this will ultimately be resolved through their bankruptcy proceedings.

Separate from the Call Option, we also sold Lehman OTC warrants, for which we received consideration, to purchase up to 3.2 million common shares at an exercise price of $126.02.  The warrants become exercisable beginning in late December 2011 and expire in January 2012. The warrants have been purchased from Lehman OTC by a third party.

The derivative transactions described above do not affect the terms of the outstanding Notes.

We maintain a revolving credit facility (the "Credit Facility") that allows for an aggregate borrowing capacity of $100.0 million. The Credit 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%.  Any outstanding balance under the Credit Facility is due in December 2010 when the Credit Facility matures.   Interest payment terms are variable depending upon the specific type of borrowing under this facility. Our available capacity is reduced by outstanding unsecured letters of credit and performance guarantees and bonds totaling $9.8 million at June 30, 2009 relating to certain projects in progress. Our available borrowing capacity under the Credit Facility at June 30, 2009 was $90.2 million.

5.  PENSIONS AND OTHER POSTRETIREMENT 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 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 net periodic pension cost under this plan for the three and six months ended June 30, 2009 and 2008 (in thousands):

During the six months ended June 30, 2009, we contributed approximately $2.4 million, as determined by the insurance company, to fund the estimated 2009 premiums on investment contracts held by the plan.

On a recurring basis, we use the market approach to value certain assets and liabilities at fair value at quoted prices in an active market (Level 1) and certain assets and liabilities using significant other observable inputs (Level 2). We do not have any assets or liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3). Gains and losses related to the fair value changes in the deferred compensation assets and liabilities are recorded in General and Administrative Expenses in the Consolidated Statements of Operations.  The following table summarizes the fair value balances (in thousands):

We have adopted a non-qualified deferred compensation plan that allows certain highly compensated employees to defer a portion of their salary, commission and bonus, as well as the amount of any reductions in their deferrals under the deferred compensation plan for employees in the United States (the "Deferred Compensation Plan"), due to certain limitations imposed by the U.S. Internal Revenue Code of 1986, as amended.  The Deferred Compensation Plan also provides for employer contributions to be made on behalf of participants equal in amount to certain forfeitures of, and/or reductions in, employer contributions that participants could have received under the 401(k) Plan in the absence of certain limitations imposed by the Internal Revenue Code. Employer contributions to the Deferred Compensation Plan vest ratably over a period of five years. Contributions to the plan are invested in equity and other investment fund assets, and carried on the balance sheet at fair value.  The benefits under these contracts are fully vested and payment of benefits generally commences as of the last day of the month following the termination of services except that the payment of benefits for select executives generally commences on the first working day following a six month waiting period following the date of termination.

6. COMMITMENTS AND CONTINGENCIES

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 us or any of our subsidiaries should not have a material adverse effect on our 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 we or any of our subsidiaries is a party will not have a material adverse effect on our consolidated results of operations or liquidity for the period in which that resolution occurs.

During the first quarter of 2008 we revised our estimate of a contingent liability associated with non-income related taxes, and as a result, a charge to income of $5.0 million was recorded in the Consolidated Statements of Operations to Other Expense (Income), net.  The contingent liability is included in Other Long-term Liabilities in the Consolidated Balance Sheet.  As a result of finalizing a settlement agreement, we released $2.5 million of the contingent liability, to Other Expense (Income), net in the Consolidated Statements of Operations during the second quarter of 2009.



7.  EQUITY



During the three months ended June 30, 2009, we repurchased 12,719 of our common shares for $1.0 million pursuant to the terms of a stock-based compensation plan, in consideration of the participants' tax burdens that may result from the issuance of common shares under this plan. During the six months ended June 30, 2009, we repurchased 134,324 of our common shares for $8.9 million. Included in this total were rights to 16,324 shares valued at $1.3 million that were surrendered to the Company pursuant to the terms of a stock-based compensation plan, in consideration of the participants' tax burdens that may result from the issuance of common shares under this plan. Such common shares, unless cancelled, may be reissued for a variety of purposes such as future acquisitions, settlement of employee stock awards, or possible conversion of the Notes.



During the three and six months ended June 30, 2009, we recognized tax benefits of $0.1 million and $0.1 million, respectively, relating 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.



On April 16, 2009, we declared a quarterly $0.10 per share of common stock dividend that was paid on May 27, 2009. In addition on July 13, 2009, we declared a quarterly dividend of $0.10 per share of common stock and a special non-recurring cash dividend of $0.75 per share of common stock for shareholders of record on July 24, 2009 and payable on August 24, 2009.

Non-controlling Interests

On January 1, 2009, we adopted Statement of Financial Accounting Standards No. 160, "Non-controlling Interests in Consolidated Financial Statements-an amendment of ARB No. 51" ("SFAS 160"). SFAS 160 requires companies with non-controlling interests to disclose such interests clearly as a portion of equity separate from the parent's equity and the amount of consolidated net income attributable to these non-controlling interests must also be clearly presented on the Consolidated Statements of Operations. In addition, when a subsidiary is deconsolidated, any retained non-controlling equity investment in the former subsidiary will be initially measured at fair value and recorded as a gain or loss. Upon adopting SFAS 160, we revised our historical presentation of non-controlling interests to be included as part of the total equity and presented the net income relating to non-controlling interests as a separate component of total net income.

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):

In 2006, we sold warrants that give the holder the right to acquire approximately 3.2 million of our common shares at an exercise price of $126.02 per share.  Included in the Senior exchangeable notes and warrants line in the table above, these warrants had no dilutive impact on our earnings per share for the three and six months ended June 30, 2009, as the average share price did not exceed the strike price of the warrants for the periods. On October 3, 2008, the dealer of the warrants filed for bankruptcy protection and subsequently sold the warrants to a third-party dealer.

During the first quarter of 2008, we revised our estimate of a contingent liability associated with non-income related taxes, and as a result, a charge to income of $5.0 million was recorded. During the second quarter of 2009 we released $2.5 million of the contingent liability as a result of finalizing a settlement agreement.  Additionally in 2008, we recorded a gain of $1.1 million in connection with the sale of a small office building.

10.  INCOME TAX EXPENSE



The effective tax rates for the second quarter of 2009 and 2008 were 37.4% and 31.1%, respectively. The effective tax rates for year to date 2009 and 2008 were 34.7% and 31.6%, respectively. The increase in the effective tax rate for the second quarter and year to date of 2009 is primarily a result in a change in activity levels between jurisdictions with different tax rates and establishment of valuation allowances against deferred tax assets in tax jurisdictions where we no longer anticipate having sufficient taxable income to fully utilize these deferred tax assets.

13. RECENT ACCOUNTING PRONOUNCEMENTS



In December 2008, the FASB issued FSP No. FAS 132(R)-1, "Employers' Disclosures about Postretirement Benefit Plan Assets" ("FSP 132(R)-1"). FSP 132(R)-1 provides guidance on an employer's disclosures about plan assets of a defined benefit pension or other postretirement plan. FSP 132(R)-1 is effective for fiscal years ending after December 15, 2009 with early adoption permitted. We are currently evaluating the impact of FSP 132(R)-1 but do not expect the pronouncement to have an impact on our financial position or results of operations.

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

The following discussion summarizes the financial position of Core Laboratories N.V. and its subsidiaries as of June 30, 2009 and should be read in conjunction with (i) the unaudited consolidated interim financial statements and notes thereto included elsewhere in this Quarterly Report on Form 10-Q and (ii) the consolidated financial statements and accompanying notes to our Annual Report on Form 10-K for the fiscal year ended December 31, 2008.

General

Core Laboratories N.V. is a Netherlands limited liability company.  It was established in 1936 and is one of the world's leading providers of proprietary and patented reservoir description, production enhancement and reservoir management products and services to the oil and gas industry.  These products and services can enable our clients to improve reservoir performance and increase oil and gas recovery from their producing fields.  Core Laboratories N.V. has over 70 offices in more than 50 countries and employs approximately 4,800 people worldwide.

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 affiliates.

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.


Cautionary Statement Regarding Forward Looking Statements

This Quarterly Report on Form 10-Q 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 Form 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 with respect to our future operations, performance, or positions or which contain other forward-looking information. These forward-looking statements are based on our current expectations and beliefs concerning future developments and their potential effect on us. While management believes that these forward-looking statements are reasonable as and when made, 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:

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, 2008, as well as the other reports filed by us with the SEC.

Outlook

We continue our efforts to expand our market presence by opening facilities in strategic areas and realizing synergies within our business lines.  We believe our market presence provides us a unique opportunity to service customers who have global operations in addition to the national oil companies.

We have established internal earnings targets for 2009 that are based primarily on market conditions existing at the time our targets are established.  Based on discussions late in 2008 with our clients and our view of the oil and gas industry, we anticipated that in 2009, spending by our international clients would soften and we expected North American spending to decrease significantly.  Given the sharp declines in commodity prices over the last 12 months and announced reductions in capital expenditure programs by certain of our clients, oilfield activity levels may not grow at the same rate as earlier expected, and in all likelihood will decrease further on a year over year basis. For example, the North American rig count was down 27% year over year in the first quarter of 2009 and for the second quarter was down 50% year over year.

Service revenues decreased to $134.7 million for the second quarter of 2009, down 13% when compared to $154.0 million for the second quarter of 2008. For the six months ended June 30, 2009, service revenues decreased 5% to $276.4 million compared to $292.4 million for the respective period in 2008.  Our service revenues declined slightly over the prior three and six months ended June 30, 2008 when oil prices had reached all time highs and natural gas prices were at record highs. We have experienced less downward pressures due to our significant international operations and projects. Some of our projects that continue to provide meaningful revenue streams are in the Middle East, Asia-Pacific, offshore deepwater regions of the Gulf of Mexico and the southern-Atlantic margins off the coast of West Africa and Brazil.

Product Sale Revenues

Revenues associated with product sales decreased to $32.6 million for the second quarter of 2009, down 25% from $43.7 million for the second quarter of 2008. For the six months ended June 30, 2009, product sale revenues decreased 18% to $69.8 million compared to $84.7 million for the same period in 2008. Our product sales revenues were impacted by the significant decline in the North American drilling activity; however, our revenues declined at a much lower rate compared to the 50% and 38% decrease in the average North American rig count year over year second quarter and year to date, respectively.  This was due primarily from the continued market penetration and acceptance of our specialized optimizing technologies introduced in 2007 and 2008, which are focused on high-end well completion and stimulation programs mainly in the Haynesville, Marcellus and Eagle Ford shale plays.

Cost of Services

Cost of services expressed as a percentage of service revenue was 63% for the quarter ended June 30, 2009, which was down from 65% for the same period in 2008.  For the six months ending June 30, 2009, cost of services expressed as a percentage of service revenue was 62% as compared to 65% for the same period for 2008.  The decline in the cost of services relative to service revenue was primarily a result of proactive expense control actions put in place to protect against potential market declines.

Cost of Sales

Cost of sales as a percentage of product sales revenues was 75% for the quarter ended June 30, 2009, up from 71% for the same period in 2008. For the six months ending June 30, 2009, cost of product sales expressed as a percentage of sales revenue was 75% up from 70% for the same period in 2008. The reduction in margins came primarily from a decline in manufacturing efficiencies, which was caused by a reduction in manufacturing due to the significant decline in North American drilling activity.

General and Administrative Expenses

General and administrative expenses totaled $6.7 million for the second quarter of 2009, down 7% from the $7.2 million incurred in the second quarter of 2008, due to an emphasis on managing costs. For the six months ended June 30, 2009 and 2008, general and administrative expenses were $0.6 million higher, at $16.0 million from $15.4 million.

Depreciation and Amortization Expense

Depreciation and amortization expense increased to $5.9 million for the second quarter of 2009, up 12% when compared to $5.3 million for the second quarter of 2008.  For the six months ended June 30, 2009, depreciation and amortization expense was $11.6 million, an increase of $1.1 million from the six months ended June 30, 2008.  This increase in depreciation and amortization expense was due to the expansion of our capital expenditure program throughout 2008 which funded our operational growth.

During the first quarter of 2008, we revised our estimate of a contingent liability associated with non-income related taxes, and as a result, a charge to income of $5.0 million was recorded. During the second quarter of 2009 we released $2.5 million of the contingent liability as a result of finalizing a settlement agreement.  Additionally in 2008, we recorded a gain of $1.1 million in connection with the sale of a small office building.

Income Tax Expense

The effective tax rates for the second quarter of 2009 and 2008 were 37.4% and 31.1%, respectively. The increase in the effective tax rate for the second quarter of 2009 is primarily a result in a change in activity levels between jurisdictions with different tax rates and establishment of valuation allowances against deferred tax assets in tax jurisdictions where we no longer anticipate having sufficient taxable income to fully utilize these deferred tax assets.

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 months ended June 30, 2009 and 2008 (in thousands):

Reservoir Description

Revenues from the Reservoir Description segment decreased 9%, or $10.7 million, to $103.5 million in the second quarter of 2009, compared to $114.2 million in the second quarter of 2008.  For the six months ended June 30, 2009 revenues decreased 4%, or $8.7 million, to $206.0 million from $214.7 million for the six months ended June 30, 2008. The revenue decrease is the result of a significant decline in oil and gas prices from record highs reached in 2008. Due to our significant international operations and projects such as our reservoir rock and reservoir fluids characterization projects, we have not experienced as significant of a decline. We have experienced increased demand in the Middle East and Asia-Pacific and for our continued large scale core analyses studies as well as crude oil and derived petroleum products characterization studies on a global basis. Other areas that continue to provide revenue growth are the continued expansion of worldwide deepwater projects in West Africa, Brazil, Gulf of Mexico and North American gas shale plays in the Eagle Ford, Haynesville, Muskwa and other active fields.

Operating income in the second quarter of 2009 increased by 8%, or $2.4 million, to $31.5 million compared to $29.1 million for the second quarter of 2008.  Operating income for the six months ended June 30, 2009 increased by 8%, or $4.1 million, to $56.2 million.  The increase in operating income for the quarter was primarily due to continued emphasis on higher value and thus higher margin services on development and production related projects in addition to the de-emphasis of the more cyclical exploration regions coupled with an emphasis on controlling costs.  Operating margins for the quarter and six months ended June 30, 2009 were 30% and 27%, respectively, compared to 25% and 24% for the same periods in 2008, respectively.

Production Enhancement

Revenues from the Production Enhancement segment decreased by 27%, or $19.7 million, to $52.0 million in the second quarter of 2009 as compared to $71.7 million in the second quarter in 2008. Revenues decreased by 17%, or $23.6 million, to $115.1 million for the six months ended June 30, 2009 as compared to $138.7 million for the same period in 2008.  The decrease in revenues is due to the significant decline in North American drilling activity; however, our decline in revenues is less than the reduction in the average rig count for North America year over year for both the quarter and year to date periods ended June 30, 2009. The downward trend in the North America rig count has continued since the latter half of 2008 and the industry outlook for the rig count remains unclear. The primary reason for the slower decline in our revenues was our focus on high-end well completion and stimulation programs and the market penetration and client acceptance of our well perforating and completion products and our fracture diagnostic services.

Operating income in the second quarter of 2009 decreased by 38%, or $8.8 million, to $14.4 million from $23.2 million for the second quarter of 2008.  Operating margins decreased to 28% in the second quarter of 2009 compared to 32% for the same period in 2008.  For the six months ended June 30, 2009, operating income decreased to $32.7 million, a decrease of 27% over the same period in 2008.  The decrease in margins were primarily due to a decline in manufacturing efficiencies from the reduction in manufacturing due to the significant decline in North American drilling activities, but has been offset somewhat by our ongoing market penetration of higher-margin services including our proprietary and patented fracture diagnostic technologies, such as our SpectraScanTM and recently introduced SpectraChem PlusTM tracer service coupled with an emphasis on controlling costs.

Revenues from the Reservoir Management segment remained flat in the second quarter of 2009 as compared to the second quarter of 2008.  Revenues for the six months ended June 30, 2009 were $25.0 million, an increase of 5% from $23.7 million from the same period in 2008. The increase in revenue was due to continued interest in several of our existing multi-client reservoir studies including such studies in the south Atlantic off the coasts of West Africa and Brazil. The recent introduction of a joint industry project evaluating the petrophysical, geochemical and production characteristics of the Eagle Ford Shale in south Texas and the introduction of a Global Gas Shale Study that examines the gas shale potential in central and southern Europe, north Africa, India, China and Australia, among other regions are expected to expand revenues in the segment along with the continued participation in our North American Gas Shale Study.

Operating income in the second quarter of 2009 increased 18% to $3.5 million from $3.0 million for the second quarter of 2008. The increase in operating income was primarily related to the mix of activity in our consortium projects and timing of analysis work on these projects.  For the six months ended June 30, 2009, operating income was $7.0 million, as compared to operating income of $7.2 million from the same period in 2008.

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 regarding the cash that was available in the period that was in excess of our needs to fund our capital expenditures and operating activities. 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. Free cash flow does not represent residual cash available for distribution because we may have other non-discretionary expenditures that are not deducted from the measure. 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 GAAP for the six months ended June 30, 2009 and 2008 (in thousands):



|                                          |  | Six Months Ended June 30, |  | % Change  
|----------------------------------------- |  | ------------------------- |  | ----------
|                                          |  | 2009                      |  | 2008      
|Free cash flow calculation:               |  | (Unaudited)               |  |           
|Net cash provided by operating activities |  | $     86,267              |  | $   73,403
|Less:  capital expenditures               |  | 5,320                     |  | 13,657    
|Free cash flow                            |  | $     80,947              |  | $   59,746

The increase in free cash flow in 2009 compared to 2008 was due to a decrease in working capital excluding cash, primarily from the greater collection of receivables over the payments made to vendors and a decrease in capital expenditures.

At June 30, 2009 and December 31, 2008, we had working capital of $203.7 million and $140.0 million, respectively. The increase in working capital is driven primarily from an increase in cash and a decrease in trade accounts payable and accrued payroll offset by a decrease in accounts receivable.

Cash Flows

The following table summarizes cash flows for the six months ended June 30, 2009 and 2008 (in thousands):



|                                        |  | Six Months Ended June 30, |  | % Change    
|--------------------------------------- |  | ------------------------- |  | ------------
|                                        |  | 2009                      |  | 2008        
|Cash provided by/(used in):             |  | (Unaudited)               |  |             
|Operating activities                    |  | $    86,267               |  | $    73,403 
|Investing activities                    |  | (5,856)                   |  | (24,053)    
|Financing activities                    |  | (13,303)                  |  | (20,339)    
|Net change in cash and cash equivalents |  | $    67,108               |  | $     29,011

The increase in cash flows provided by operating activities was primarily attributable to a reduction in receivables partially offset by a reduction in liabilities.

Cash flows used in investing activities declined slightly due to a decrease in capital expenditures for the period of $8.3 million and an acquisition in 2008 for $13.0 million offset by a reduction in the cash proceeds from the sale of assets.

The decrease in cash flows used in financing activities related primarily to a decrease in the number of shares repurchased under our common share repurchase program.  In the first six months of 2009, we repurchased 134,324 shares for an aggregate price of $8.9 million compared to 260,541 shares for an aggregate price of $29.8 million during the same period in 2008. The decrease in cash flows used in financing activities was also attributable to a reduction in the excess tax benefits from stock-based compensation that was recognized in 2009 offset by dividends of $4.6 million paid in 2009 and the net reduction in debt of $2.3 million.

We maintain a revolving credit facility (the "Credit Facility") that allows for an aggregate borrowing capacity of $100.0 million. The Credit 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%.  Any outstanding balance under the Credit Facility is due in December 2010 when the Credit Facility matures.   Interest payment terms are variable depending upon the specific type of borrowing under this facility. Our available capacity is reduced by outstanding unsecured letters of credit and performance guarantees and bonds totaling $9.8 million at June 30, 2009 relating to certain projects in progress. Our available borrowing capacity under the Credit Facility at June 30, 2009 was $90.2 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, 2009.  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, dividend payments and future acquisitions.

Recent Accounting Pronouncements

In December 2008, the FASB issued FSP No. FAS 132(R)-1, "Employers' Disclosures about Postretirement Benefit Plan Assets" ("FSP 132(R)-1"). FSP 132(R)-1 provides guidance on an employer's disclosures about plan assets of a defined benefit pension or other postretirement plan. FSP 132(R)-1 is effective for fiscal years ending after December 15, 2009 with early adoption permitted. We are currently evaluating the impact of FSP 132(R)-1 but do not expect the pronouncement to have an impact on our financial position or results of operations.

Item 3. Quantitative and Qualitative Disclosures About 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 for the fiscal year ended December 31, 2008.



Item 4. Controls and Procedures

A complete discussion of our controls and procedures is included in our Annual Report on Form 10-K for the year ended December 31, 2008.

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 our 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 Officer have concluded that our disclosure controls and procedures were effective as of June 30, 2009 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 been no changes in our system of 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, 2009, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
