NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1. Basis of Presentation

The accompanying unaudited consolidated financial statements, which include the accounts of Schlumberger Limited and its subsidiaries (“Schlumberger”), have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation have been included in the accompanying unaudited financial statements. All intercompany transactions and balances have been eliminated in consolidation. Operating results for the three month period ended March 31, 2010 are not necessarily indicative of the results that may be expected for the full year ending December 31, 2010. The December 31, 2009 balance sheet information has been derived from the audited 2009 financial statements. For further information, refer to the Consolidated Financial Statements and notes thereto, included in the Schlumberger Annual Report on Form 10-K for the year ended December 31, 2009, filed with the Securities and Exchange Commission on February 5, 2010.

Certain items from prior year have been reclassified to conform to the current year presentation.

2. Recently Announced Transactions

On February 21, 2010, Schlumberger and Smith International, Inc. (“Smith”) jointly announced that their Boards of Directors approved a definitive merger agreement in which the companies would combine in a stock-for-stock transaction. Under the terms of the agreement, Smith shareholders will receive 0.6966 shares of Schlumberger in exchange for each Smith share. Schlumberger estimates that it will issue approximately 177 million shares of its common stock in this transaction. The value of this transaction using the Schlumberger’s stock price at the end of March is approximately $11.2 billion. Such amount excludes Smith’s net debt which was $1.2 billion as of December 31, 2009. Smith is a leading supplier of premium products and services to the oil and gas exploration and production industry and reported revenues of $8.2 billion in 2009. The transaction is subject to various conditions including Smith stockholder approval and customary regulatory approvals, including the expiration of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976. It is anticipated that the closing of the transaction will occur in the latter half of 2010.

On March, 24, 2010, Schlumberger announced the acquisition of Geoservices, a privately owned oilfield services company specializing in mud logging, slickline and production surveillance operations. The purchase price is approximately $0.9 billion, excluding net debt assumed of approximately $0.1 billion. Geoservices’ revenue in 2009 was approximately $0.5 billion. This transaction closed on April 23, 2010.

3. Charges

Schlumberger recorded the following charges during the first quarter of 2010:

• Schlumberger incurred $35 million of merger-related costs in connection with the Smith and Geoservices transactions. These costs primarily consist of advisory and legal fees and are classified in Merger & integration in the Consolidated Statement of Income.

• During March 2010, the Patient Protection and Affordable Care Act (PPACA) was signed into law in the United States. Among other things, the PPACA eliminates the tax deductibility of retiree prescription drug benefits to the extent of the Medicare Part D Subsidy that companies, such as Schlumberger, receive. As a result of this change in law, Schlumberger recorded a $40 million charge to adjust its deferred tax assets to reflect the loss of this future tax deduction. This charge is classified in Taxes on income in the Consolidated Statement of Income.

The following is a summary of these charges:

	(Stated in millions)
	Pretax		Tax		Net
Charges
- Merger-related transaction costs	$	35	$	—	$	35
- Impact of elimination of tax deduction related to Medicare Part D subsidy		—		40		40
	$	35	$	40	$	75

There were no charges in the first quarter of 2009.

4. Earnings Per Share

The following is a reconciliation from basic earnings per share of Schlumberger to diluted earnings per share of Schlumberger:

						(Stated in millions, except per share amounts)
	2010					2009
	Schlumberger Net Income		Average Shares Outstanding	Earnings per Share		Schlumberger Net Income		Average Shares Outstanding	Earnings per Share

The number of outstanding options to purchase shares of Schlumberger common stock which were not included in the computation of diluted earnings per share, because to do so would have had an antidilutive effect, were as follows:

	(Stated in millions)
	2010	2009
First Quarter	13	17

5. Acquisitions

During the first quarter of 2010, Schlumberger made certain acquisitions and minority interest investments for $117 million, net of cash acquired, none of which were significant on an individual basis or in the aggregate.

10. Intangible Assets

Intangible assets principally comprise software, technology and customer relationships. The gross book value and accumulated amortization of intangible assets were as follows:

							(Stated in millions)
	Mar. 31, 2010						Dec. 31, 2009
	Gross Book Value		Accumulated Amortization		Net Book Value		Gross Book Value		Accumulated Amortization		Net Book Value
Software	$	328	$	256	$	72	$	339	$	262	$	77
Technology		595		163		432		527		163		364
Customer Relationships		357		86		271		355		80		275
Other		121		56		65		121		51		70
	$	1,401	$	561	$	840	$	1,342	$	556	$	786

10

Amortization expense charged to income was $28 million during the first quarter of 2010 and $29 million during the same period of 2009.

The weighted average amortization period for all intangible assets is approximately 12 years.

Based on the net book value of intangible assets at March 31, 2010, amortization charged to income for the subsequent five years is estimated to be: remainder of 2010 – $91 million; 2011 – $109 million; 2012– $90 million; 2013 – $73 million; 2014 – $68 million and 2015 – $61 million.

11. Derivative Instruments and Hedging Activities

Schlumberger is exposed to market risks related to fluctuations in foreign currency exchange rates, commodity prices and interest rates. To mitigate these risks, Schlumberger utilizes derivative instruments. Schlumberger does not enter into derivatives for speculative purposes.

Foreign Currency Exchange Rate Risk

As a multinational company, Schlumberger conducts its business in approximately 80 countries. Schlumberger’s functional currency is primarily the US dollar, which is consistent with the oil and gas industry. However, outside the United States, a significant portion of Schlumberger’s expenses is incurred in foreign currencies. Therefore, when the US dollar weakens (strengthens) in relation to the foreign currencies of the countries in which Schlumberger conducts business, the US dollar – reported expenses will increase (decrease).

Schlumberger is exposed to risks on future cash flows to the extent that local currency expenses exceed revenues denominated in local currency that are other than the functional currency. Schlumberger uses foreign currency forward contracts and foreign currency options to provide a hedge against a portion of these cash flow risks. These contracts are accounted for as cash flow hedges, with the effective portion of changes in the fair value of the hedge recorded on the Consolidated Balance Sheet and in Other Comprehensive Income (Loss). Amounts recorded in Other Comprehensive Income (Loss) are reclassified into earnings in the same period or periods that the hedged item is recognized in earnings. The ineffective portion of changes in the fair value of the hedged item is recorded directly to earnings.

At March 31, 2010, Schlumberger recognized a cumulative net $18 million gain in Equity relating to revaluation of foreign currency forward contracts and foreign currency options designated as cash flow hedges, the majority of which is expected to be reclassified into earnings within the next twelve months.

Schlumberger is also exposed to changes in the fair value of assets and liabilities, including certain of its long-term debt, which are denominated in currencies other than the functional currency. Schlumberger uses foreign currency forward contracts and foreign currency options to hedge this exposure as it relates to certain currencies. These contracts are accounted for as fair value hedges with the fair value of the contracts recorded on the Consolidated Balance Sheet and changes in the fair value recognized in the Consolidated Statement of Income along with the change in fair value of the hedged item.

At March 31, 2010, contracts were outstanding for the US dollar equivalent of $4.3 billion in various foreign currencies.

Commodity Price Risk

Schlumberger is exposed to the impact of market fluctuations in the price of commodities, such as copper and lead. Schlumberger has entered into forward contracts on these commodities to manage the price risk associated with forecasted purchases. The objective of these contracts is to reduce the variability of cash flows associated with the forecasted purchase of those commodities. These contracts do not qualify for hedge accounting treatment and therefore, changes in the fair value of the forward contracts are recorded directly to earnings.

11

Interest Rate Risk

Schlumberger is subject to interest rate risk on its debt and its investment portfolio. Schlumberger maintains an interest rate risk management strategy that uses a mix of variable and fixed rate debt combined with its investment portfolio and interest rate swaps to mitigate the exposure to changes in interest rates.

During the third quarter of 2009, Schlumberger entered into interest rate swaps relating to two of its debt instruments. The first swap was for a notional amount of $600 million in order to hedge a portion of the changes in fair value of Schlumberger’s $650 million 6.50% Notes due 2012. Under the terms of this swap agreement, Schlumberger will receive interest at a fixed rate of 6.5% semi-annually and will pay interest semi-annually at a floating rate of one-month LIBOR plus a spread of 4.84%. The second swap was for a notional amount of $450 million in order to hedge changes in the fair value of Schlumberger’s $450 million 3.00% Notes due 2013. Under the terms of this swap, Schlumberger will receive interest at a fixed rate of 3.0% annually and will pay interest quarterly at a floating rate of three-month LIBOR plus a spread of 0.765%.

These interest rate swaps are designated as fair value hedges of the underlying debt. These derivative instruments are marked to market with gains and losses recognized currently in income to offset the respective losses and gains recognized on changes in the fair value of the hedged debt. This results in no net gain or loss being recognized in the Consolidated Statement of Income.

At March 31, 2010, Schlumberger had fixed rate debt aggregating approximately $3.0 billion and variable rate debt aggregating approximately $2.0 billion, after taking into account the effects of the interest rate swaps.

Short-term investments and Fixed income investments, held to maturity, totaled approximately $4.6 billion at March 31, 2010, and are comprised primarily of money market funds, eurodollar time deposits, certificates of deposit, commercial paper, euro notes and Eurobonds, and are substantially all denominated in US dollars. The carrying value of these investments approximates fair value, which was estimated using quoted market prices for those or similar investments.

The fair value adjustment presented above represents changes in the fair value of the portion of Schlumberger’s fixed rate debt that is hedged through the use of interest rate swaps.

The fair value of Schlumberger’s Long-term Debt at March 31, 2010 and December 31, 2009 was $4.3 billion and $4.6 billion, respectively and was estimated based on quoted market prices.

At March 31, there were $299 million outstanding of 2.125% Series B Convertible Debentures due June 1, 2023. During the first quarter of 2010, approximately $22 million of these debentures were converted by holders into 565,000 shares of Schlumberger common stock. On June 1, 2010, holders may require Schlumberger to repurchase their Series B debentures for cash. Accordingly, these debentures are classified within Current Liabilities on the Consolidated Balance Sheet at March 31, 2010. The fair value of these Series B debentures at March 31, 2010 and December 31, 2009 was $705 million and $527 million, respectively. For further information regarding the debentures refer to Note 11 to the Consolidated Financial Statements included in the Schlumberger Annual Report on Form 10-K for the year ended December 31, 2009.

14. Contingencies

In 2007, Schlumberger received an inquiry from the United States Department of Justice (“DOJ”) related to the DOJ’s investigation of whether certain freight forwarding and customs clearance services of Panalpina, Inc., and other companies provided to oil and oilfield service companies, including Schlumberger, violated the Foreign Corrupt Practices Act. Schlumberger is cooperating with the DOJ and is currently continuing its own investigation with respect to these services.

In 2009, Schlumberger learned that United States officials began a grand jury investigation and an associated regulatory inquiry, both related to certain Schlumberger operations in specified countries that are subject to United States trade and economic sanctions. Schlumberger is cooperating with the governmental authorities and is currently unable to predict the outcome of these matters.

Schlumberger and its subsidiaries are party to various other legal proceedings from time to time. A liability is accrued when a loss is both probable and can be reasonably estimated. At this time the ultimate disposition of these proceedings is not determinable and therefore, it is not possible to estimate the amount of loss or range of possible losses that might result from an adverse judgment or settlement in any of these matters. However, in the opinion of management, any liability that might ensue would not be material in relation to Schlumberger’s consolidated liquidity, financial position or future results of operations.

15. Segment Information

Schlumberger operates two business segments: Oilfield Services and WesternGeco.

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

BUSINESS REVIEW

First Quarter 2010 Compared to Fourth Quarter 2009

			(Stated in millions)
	First Quarter 2010		Fourth Quarter 2009		% chg
Oilfield Services
Revenue	$	5,097	$	5,170	(1	)%
Pretax Operating Income	$	969	$	1,006	(4	)%
WesternGeco
Revenue	$	472	$	549	(14	)%
Pretax Operating Income	$	67	$	115	(41	)%

Pretax operating income represents the segments’ income before taxes and noncontrolling interests. The pretax operating income excludes such items as corporate expenses and interest income and interest expense not allocated to the segments as well as the charges described in detail in Note 3 to the Consolidated Financial Statements, interest on postretirement medical benefits and stock-based compensation costs.

First-quarter 2010 revenue was $5.60 billion versus $5.74 billion in the fourth quarter of 2009. Income from continuing operations attributable to Schlumberger was $672 million versus $817 million in the previous quarter. First-quarter 2010 results included charges of $40 million for the reduction in future tax deductions for retiree medical benefits as a result of the passage during the quarter of the Patient Protection and Affordable Care Act in the United States and $35 million for transaction costs in connection with the Smith International, Inc. merger and the Geoservices acquisition.

Oilfield Services first-quarter revenue was down 1% sequentially as a strong performance in North America and continued strength in the Middle East and Asia offset an overall decline in product and software sales from the high levels of the fourth quarter and a sharp drop in the North Sea and Russia primarily due to lower drilling activity and adverse weather. North American margins improved in all GeoMarkets as activity increased. While strong performances were recorded in the Latin America and Middle East and Asia Areas, overall international margins decreased slightly due to adverse winter weather conditions in the Europe, Africa and CIS Area.

WesternGeco registered a sequential decline in Multiclient revenue following the traditional fourth quarter surge while Marine activity improved slightly with higher vessel utilization.

Schlumberger’s outlook for the remainder of 2010 confirms the optimism expressed at the beginning of the year. At WesternGeco, while the second quarter will see increased vessel transits, strong tendering activity in Marine is leading to much improved visibility on the remainder of 2010 and utilization will be higher than originally planned. However, new capacity entering the market is likely to limit pricing gains until later in the year. In North America, commitment drilling to hold leases as well as interest in domestic oil plays should sustain current activity levels in the US through the second quarter, while Canada will experience the normal spring break-up. Beyond that, the picture is less clear as natural gas prices and the fundamentals of the natural gas market remain uncertain. Higher oil prices are leading to tangible evidence that operators are contemplating higher levels of activity than originally planned in international markets. Schlumberger reiterates its comment from the last quarter that we see improvements in some offshore markets notably the UK sector of the North Sea, Latin America and West Africa as well as on land in Russia.

Two significant events were announced during the quarter—the proposed merger with Smith International, Inc. and the planned acquisition of Geoservices.

18

In the proposed merger with Smith, the companies’ complementary products and services will lead to the development of engineered drilling systems that optimize all the components of the drillstring to allow customers to drill more economically in demanding conditions. This step change in drilling performance and well productivity will come from combining measurement and steering capabilities with the engineering and design of the complete bottom-hole assembly and its various components—including the drilling fluid and the drillbit.

The addition of Geoservices mud-logging technology to the Schlumberger portfolio will also be an important step in the development of higher-performance drilling systems. The combination of Schlumberger real-time downhole measurements with Geoservices’ drilling mud analysis will help customers better identify and react to drilling hazards, while the combination of mud logging with Schlumberger formation evaluation measurements will bring a more complete understanding of rock lithology and fluid content.

In addition to Geoservices’ mud-logging technology and expertise, Geoservices’ footprint, expertise and technology in slickline well intervention and field production surveillance will complement existing Schlumberger activities.

OILFIELD SERVICES

First-quarter revenue of $5.10 billion decreased 1% sequentially. The Europe/CIS/Africa Area revenue decreased significantly from lower Testing Services equipment sales and Schlumberger Information Solutions (SIS) software sales in addition to the effects of severe weather in Russia and activity slow-downs in the North Sea and Libya GeoMarkets. Latin America Area revenue fell mostly from a slow-down in activity in Mexico/Central America as well as from currency devaluation and lower Integrated Project Management (IPM) revenue in Venezuela. These decreases were partially offset by an improvement in activity across North America. Middle East & Asia Area revenue was essentially flat with the previous quarter.

Among the Technologies, sequential revenue declines were most notable in SIS and Artificial Lift resulting from lower software and product sales following the seasonally strong fourth quarter, and in Testing Services following the completion of large equipment sale deliveries in Europe/CIS/Africa in the fourth quarter. These decreases were partially offset by an increase in Well Services revenue, which was largely attributable to the activity increase in North America.

First-quarter pretax operating income of $969 million fell 4% sequentially. Pretax operating margin slipped 46 basis points (bps) sequentially to 19.0% primarily due to lower sales of SIS software, Testing Services equipment and Artificial Lift products; reduced activity in Russia and the North Sea; and the impact of lower pricing in international markets. These effects were partially offset by the impact of the improved activity in North America.

North America

Revenue of $1.03 billion was 18% higher compared to the fourth quarter of 2009. Pretax operating income of $83 million improved 359% versus the fourth quarter of 2009.

All North America GeoMarkets recorded revenue growth. US Land grew on increased drilling activity coupled with pockets of pricing improvements that benefited Well Services technologies. Canada experienced significant growth as the result of a strong winter drilling season, particularly for oil basins in the West, which led to higher demand for Well Services, Wireline and Drilling & Measurements services. US Gulf of Mexico revenue was higher sequentially on increased shelf and deepwater activity that resulted in strong demand for Drilling & Measurements, Testing Services and Wireline technologies. Alaska revenue grew from seasonally high exploration activity.

19

Pretax operating margin increased 594 bps sequentially to 8.0% primarily due to the increased activity across the Area, supplemented by the pricing improvements for Well Services technologies.

Latin America

Revenue of $1.06 billion decreased 6% sequentially. Sequentially, pretax operating income of $185 million increased 4%.

Mexico/Central America GeoMarket revenue decreased primarily due to weather-related slow-downs that affected offshore activity and to delays in the finalization of contracts for SIS and Data & Consulting Services activities. Venezuela/Trinidad & Tobago GeoMarket revenue fell from the impact of the devaluation of the Venezuelan currency and from the absence of deferred revenue recognized in the prior quarter, the effects of which were partially offset by increased demand for SIS software. Revenue in the Brazil and Peru/Columbia/Ecuador GeoMarkets decreased mostly due to lower Completions products and SIS software sales partially offset by an increase in IPM activity. Argentina/Bolivia/Chile GeoMarket revenue decreased primarily due to lower SIS software sales.

Pretax operating margin increased 174 bps sequentially to 17.5% primarily due to a more favorable revenue mix and wellsite efficiency improvements for IPM in the Mexico/Central America GeoMarket and to the positive impact of the currency devaluation along with a more favorable revenue mix in the Venezuela/Trinidad & Tobago GeoMarket.

Europe/CIS/Africa

Revenue of $1.63 billion decreased 9% versus the prior quarter. Pretax operating income of $294 million was down 24% sequentially.

The fall in revenue was largely due to lower Testing Services equipment sales and SIS software sales, the effect of lower pricing, and the weakening of local currencies against the US dollar. Among the GeoMarkets, revenue in the North Sea decreased resulting from a combination of lower drilling activity that impacted Drilling & Measurements; delays in project start-ups that affected Testing Services; and lower Well Services stimulation activities. Russia revenue was lower primarily as the result of severe winter weather while Libya GeoMarket revenue fell on early completion of exploration campaigns.

Pretax operating margin decreased 353 bps to 18.1% primarily due to the reduced activity in Russia and the North Sea; the lower Testing Services and SIS sales; and the generally lower pricing in the Area.

Middle East & Asia

Revenue of $1.32 billion was essentially flat compared to the previous quarter. Pretax operating income of $410 million was 4% lower sequentially.

Growth was recorded in the Australia/Papua New Guinea and East Mediterranean GeoMarkets from increased offshore activity while East Asia GeoMarket revenue increased on higher IPM activity. These increases were offset across much of the Area by decreases in Artificial Lift product and SIS software sales following the year-end seasonal surge, and by lower activity in the Arabian, Gulf, Qatar and Indonesia GeoMarkets.

Pretax operating margin fell 136 bps sequentially to 31.0% primarily due to the lower activity and less favorable revenue mix in the Arabian, Gulf, Qatar and Indonesia GeoMarkets as well as the lower Artificial Lift and SIS sales across the Area.

20

WESTERNGECO

First-quarter revenue of $472 million decreased 14% versus the fourth quarter of 2009. Pretax operating income of $67 million decreased 41% sequentially.

Increased Marine revenue from high vessel utilization was more than to offset by a fall in Multiclient revenue following the year-end surge in North America sales and lower Land revenue due to completion of contracts in the Middle East and North Africa.

Pretax operating margin declined 659 bps sequentially to 14.3% reflecting the reduced Multiclient sales and decreased Land activity.

Revenue backlog was $940 million at March 31, 2010, compared to $1.0 billion at December 31, 2009.

First Quarter 2010 Compared to First Quarter 2009

First-quarter 2010 revenue was $5.60 billion versus $6.00 billion in the first quarter of 2009. Income from continuing operations attributable to Schlumberger was $672 million, a decrease of 28% year-on-year, and included the previously mentioned charges of $75 million.

OILFIELD SERVICES

First-quarter 2010 revenue of $5.10 billion was 6% lower compared to the same period last year primarily from reduced activity and generally lower pricing in the Europe/CIS/Africa, North America and Middle East & Asia Areas. However, these decreases were partially offset by growth in the Latin America Area as the result of higher IPM activity in the Brazil and Peru/Colombia/Ecuador GeoMarkets partially offset by a slow-down in activity in the Mexico/Central America and the Venezuela/Trinidad & Tobago GeoMarkets in addition to the negative impact of the devaluation of Venezuelan currency. Among the Technologies, revenue decreases were highest in Drilling & Measurements, Well Services and Wireline.

First-quarter 2010 pretax operating income of $969 million was 23% lower year-on-year. Pretax operating margin declined 408 bps to 19.0% mostly as the result of the lower activity and pricing in the Europe/CIS/Africa, North America and Middle East & Asia Areas and to a less favorable revenue mix in Latin America.

North America

First-quarter 2010 revenue of $1.03 billion fell 13% versus the same period last year as continued low natural gas prices resulted in a drop in activity and significantly lower pricing in the US Land, Canada and US Gulf of Mexico GeoMarkets.

Year-on-year, pretax operating margin decreased 567 percentage bps to 8.0% primarily due to the impact of the lower activity across the Area and the related pricing erosion that was most acute for Well Services and Wireline technologies.

21

Latin America

First-quarter 2010 revenue of $1.06 billion was 3% higher than the same period last year primarily due to increased IPM activity in the Brazil and Peru/Colombia/Ecuador GeoMarkets. These increases were partially offset by lower revenue in the Venezuela/Trinidad & Tobago GeoMarket as the result of a significant drop in activity and the impact of the devaluation of the Venezuelan currency and in the Mexico/Central America GeoMarket due to reduced non-IPM related activity.

Year-on-year, pretax operating margin was down 216 bps to 17.5% primarily due to a less favorable revenue mix in the Mexico/Central America and Brazil GeoMarkets partially offset by the positive impact from the devaluation of the Venezuelan currency.

Europe/CIS/Africa

First-quarter 2010 revenue of $1.63 billion was 10% lower year-on-year. The decrease was largely attributable to reduced activity coupled with the impact of lower pricing that affected the North Sea, Caspian, Continental Europe, West & South Africa and Libya GeoMarkets as well as Russia. Among the Technologies, revenue decreases were most notable in Drilling & Measurements and Wireline. These decreases were partially offset by an increase in the North Africa GeoMarket on increased IPM activity and strong Testing Services equipment sales.

Year-on-year, pretax operating margin decreased 785 bps to 18.1% primarily as the result of the lower overall activity and the impact of generally lower pricing across the Area.

Middle East & Asia

First-quarter 2010 revenue of $1.32 billion was 4% below the same period last year mostly due to lower exploration-related activity in the Gulf, East Mediterranean and Qatar GeoMarkets as well as reduced pricing across the Area. These decreases were partially offset by an increase in the Australia/Papua New Guinea GeoMarket revenue as a result of stronger offshore drilling activity and an increase in the East Asia GeoMarket revenue from higher IPM activity.

Year-on-year, pretax operating margin decreased 209 bps to 31.0% primarily due to the reduced mix of high margin exploration-related services in the Gulf and East Mediterranean GeoMarkets, a less favorable revenue mix in the East Asia GeoMarket and the impact of the lower pricing across the Area.

WESTERNGECO

First-quarter 2010 revenue of $472 million was 14% lower year-on-year primarily in Marine as the result of reduced activity and lower pricing. However, this decrease was partially offset by an increase in Multiclient revenue due to sales of new wide-azimuth multiclient surveys in the US Gulf of Mexico.

Year-on-year, pretax operating margin increased 435 points to 14.3% mostly on the higher Multiclient revenue partially offset by the reduced activity and lower pricing in Marine.

Interest & Other Income

Interest & other income consisted of the following for the first quarters of 2010 and 2009:

	(Stated in millions)
	First Quarter
	2010		2009
Interest income	$	17	$	18
Equity in net earnings of affiliated companies		47		59
	$	64	$	77

22

The decrease in equity in net earnings of affiliated companies was primarily due to the results of the M-I SWACO drilling fluids joint venture between Schlumberger and Smith International, Inc.

Other

Gross margin was 22.4% and 24.8% in the first quarter of 2010 and 2009, respectively. The decrease in gross margin was largely due to lower activity and consequent pricing pressure for Oilfield Services particularly in the Europe/CIS/Africa, North America, and Middle East & Asia Areas.

Research & engineering and General & administrative expenses, as a percentage of Revenue, for the first quarter ended March 31, 2010 and 2009 were as follows:

	First Quarter
	2010		2009
Research & engineering	3.7	%	3.2	%
General & administrative	2.6	%	2.2	%

Research and engineering expenditures, by business segment, for the first quarter ended March 31, 2010 and 2009 were as follows:

Oilfield Services	$	177	$	158
WesternGeco		27		27
Other		3		5
	$	207	$	190

The effective tax rate for the first quarter of 2010 was 24.1% compared to 21.1% for the same period in 2009. The charges described in Note 3 to the Consolidated Financial Statements negatively impacted the effective tax rate in the first quarter of 2010 by approximately 5 percentage points. Excluding the impact of these charges the effective tax rate decreased as compared to the same period last year. This decrease was primarily attributed to the lower proportion of pretax earnings in North America in the first quarter of 2010 as compared to the first quarter of 2009.

CHARGES

Schlumberger recorded charges during the first quarter of 2010. These charges, which are summarized below, are more fully described in Note 3 to the Consolidated Financial Statements.

Key liquidity events during the first three months of 2010 and 2009 included:

• During the first quarter of 2009, Schlumberger entered into a €3.0 billion Euro Medium Term Note program. This program provides for the issuance of various types of debt instruments such as fixed or floating rate notes in Euro, US dollar or other currencies.

During the first quarter of 2009, Schlumberger issued €1.0 billion 4.50% Guaranteed Notes due 2014 under this program. Schlumberger entered into agreements to swap these euro notes for US dollars on the date of issue until maturity, effectively making this a US dollar denominated debt on which Schlumberger will pay interest in US dollars at a rate of 4.95%. The proceeds from these notes were used to refinance existing debt obligations and for general corporate purposes.

• On April 17, 2008, the Schlumberger Board of Directors approved an $8 billion share repurchase program for shares of Schlumberger common stock, to be acquired in the open market before December 31, 2011, of which $1.77 billion had been repurchased as of March 31, 2010.

The following table summarizes the activity, during the first quarter of 2010, under the April 17, 2008 share repurchase program:

			(Stated in thousands, except per share amounts)
	Total cost of shares purchased		Total number of shares purchased	Average price paid per share
First quarter of 2010	$	337,262	5,292.8	$	63.72

Schlumberger did not repurchase any shares during the first three months of 2009.

• During the first quarter of 2010 Schlumberger made contributions of $64 million to its defined benefit pension plans as compared to $273 million during the same period last year.

• Cash flow provided by operations was $1.0 billion in the first quarter of 2010 compared to $551 million in the first quarter of 2009. The increase in cash flow from operations in 2010 as compared to 2009 reflected an improvement in working capital requirements combined with a decrease in pension plan contributions which was offset in part by the decrease in net income.

• Capital expenditures were $0.4 billion in the first quarter of 2010 compared to $0.7 billion during the first quarter of 2009. Oilfield Services capital expenditures are expected to approach $2.8 billion for the full year of 2010 as compared to $1.9 billion in 2009. WesternGeco capital expenditures are expected to approach $0.3 billion for the full year 2010 as compared to $0.5 billion in 2009.

• During the first quarter of 2010 approximately, $22 million of the 2.125% Series B Convertible Debentures due June 1, 2023 were converted by holders into 565,000 shares of Schlumberger common stock.

As of March 31, 2010 Schlumberger had $4.2 billion of cash and short-term investments on hand. Schlumberger had separate committed debt facility agreements aggregating $3.8 billion with commercial banks, of which $2.9 billion was available and unused as of March 31, 2010. This included $2.3 billion of unused committed facilities which support commercial paper borrowings in the United States and Europe. Schlumberger believes that these amounts are sufficient to meet future business requirements for at least the next twelve months.

Schlumberger’s total outstanding debt at March 31, 2010 was $5.0 billion and included $0.2 billion of commercial paper borrowings. The total outstanding debt decreased $0.5 billion compared to December 31, 2009.

Although the functional currency of Schlumberger’s operations in Venezuela is the US dollar, a portion of the transactions are denominated in local currency. For financial reporting purposes, such transactions are remeasured into US dollars at the official exchange rate, which until January 2010 was fixed at 2.15 Venezuela bolivares fuertes per US dollars, despite significant inflation in recent periods. In January 2010, Venezuela’s currency was devalued and a new dual exchange rate system was announced. During the first quarter of 2010, Schlumberger began to apply an exchange rate of 4.3 Venezuelan bolivares fuertes per US dollar to its local currency denominated transactions in Venezuela. The devaluation did not have an immediate significant impact to Schlumberger. Further, although this devaluation does result in a reduction in the US dollar reported amount of local currency denominated revenues and expenses, the impact is not material to Schlumberger’s consolidated financial statements.

FORWARD-LOOKING STATEMENTS

This Form 10-Q and other statements we make contain “forward-looking statements” within the meaning of the federal securities laws, which include any statements that are not historical facts, such as our forecasts or

These statements are subject to risks and uncertainties, including, but not limited to, the current global economic downturn; changes in exploration and production spending by Schlumberger’s customers and changes in the level of oil and natural gas exploration and development; general economic and business conditions in key regions of the world; pricing erosion; seasonal factors; satisfaction of the closing conditions to the Smith merger; the risk that the contemplated Smith merger does not occur, negative effects from the pendency of the contemplated Smith merger, the ability after the closing of the Smith merger to successfully integrate the merged businesses and to realize expected synergies, the inability to retain key employees; costs and expenses for the merger; and other risks and uncertainties detailed in our first-quarter 2010 earnings release, our most recent Form 10-K and other filings that we make with the Securities and Exchange Commission. If one or more of these risks or uncertainties materialize (or the consequences of such a development changes), or should underlying assumptions prove incorrect, actual outcomes may vary materially from those forecasted or expected. Schlumberger disclaims any intention or obligation to update publicly or revise such statements, whether as a result of new information, future events or otherwise.

Item 3. Quantitative and Qualitative Disclosures about Market Risk.

For quantitative and qualitative disclosures about market risk affecting Schlumberger, see Item 7A, “Quantitative and Qualitative Disclosures about Market Risk,” of the Schlumberger Annual Report on Form 10-K for the fiscal year ended December 31, 2009. Schlumberger’s exposure to market risk has not changed materially since December 31, 2009.

Item 4. Controls and Procedures.

Schlumberger has carried out an evaluation under the supervision and with the participation of Schlumberger’s management, including the Chief Executive Officer (“CEO”) and the Chief Financial Officer (“CFO”), of the effectiveness of Schlumberger’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 (the “Exchange Act”)) as of the end of the period covered by this report. Based on this evaluation, the CEO and the CFO have concluded that, as of the end of the period covered by this report, Schlumberger’s disclosure controls and procedures were effective to provide reasonable assurance that information required to be disclosed in the reports that Schlumberger files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms. Schlumberger’s disclosure controls and procedures include controls and procedures designed to ensure that information required to be disclosed in reports filed or submitted under the Exchange Act is accumulated and communicated to its management, including the CEO and the CFO, as appropriate, to allow timely decisions regarding required disclosure. There has been no change in Schlumberger’s internal control over financial reporting that occurred during the quarter to which this report relates that has materially affected, or is reasonably likely to materially affect, Schlumberger’s internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings.

The information with respect to Item 1 is set forth under Note 13. Contingencies, in the Consolidated Financial Statements.

Item 1A. Risk Factors.

As of the date of this filing, there have been no material changes from the risk factors previously disclosed in Part 1, Item 1A, of Schlumberger’s Annual Report on Form 10-K for the fiscal year ended December 31, 2009, except as follows:

The ability of Smith and Schlumberger to complete the merger is subject to certain closing conditions, including the approval of Smith stockholders and the receipt of consents and approvals from government entities, which may impose conditions that could adversely affect the combined company or cause the merger to be abandoned.

The merger agreement contains closing conditions, including approval of the merger by Smith stockholders, the absence of injunctions or other legal restrictions and no material adverse effect having occurred with respect to either company. In addition, Smith and Schlumberger will be unable to complete the merger until approvals are received from the Antitrust Division of the U.S. Department of Justice, the European Commission and various other governmental entities. We can provide no assurance that the various closing conditions will be satisfied and that the necessary approvals will be obtained, or that any required conditions will not materially adversely affect the combined company following the merger. In addition, we can provide no assurance that these conditions will not result in the abandonment or delay of the merger.

Failure to complete the merger with Smith could negatively impact Schlumberger’s stock price and our future business and financial results.

If the merger with Smith is not completed, the ongoing businesses and the market price of the common stock of Schlumberger may be adversely affected and Schlumberger will be subject to several risks, including being required, under specified circumstances, to pay Smith a termination fee of $615 million; having to pay certain costs relating to the merger; and diverting the focus of management from pursuing other opportunities that could be beneficial to Schlumberger, in each case, without realizing any of the benefits that might have resulted had the merger been completed.

The pendency of the merger could adversely affect Schlumberger.

In connection with the pending merger, some of Schlumberger’s customers may delay or defer purchasing decisions, which could negatively impact revenues, earnings and cash flows regardless of whether the merger is completed. Additionally, Schlumberger has agreed in the merger agreement to refrain from taking certain actions with respect to its business and financial affairs during the pendency of the merger. These restrictions could be in place for an extended period of time if completion of the merger is delayed, and could adversely impact Schlumberger’s financial condition, results of operations or cash flows.

Schlumberger’s stockholders will be diluted by the merger.

The merger will dilute the ownership position of Schlumberger’s current stockholders. We currently estimate that, upon completion of the merger, Schlumberger’s stockholders before the merger will own approximately 87% of the combined company and former Smith stockholders will own approximately 13% of the combined company’s outstanding common stock.

27

Following the merger, Schlumberger may be unable to successfully integrate Smith’s and Schlumberger’s businesses and realize the anticipated benefits of the merger.

The merger involves the combination of two companies that currently operate as independent public companies. Schlumberger will be required to devote management attention and resources to integrating the two companies’ business practices and operations. Potential difficulties that Schlumberger may encounter in the integration process include the following:

• the inability to integrate the Smith and Schlumberger businesses in a manner that permits Schlumberger to achieve the cost savings and operating synergies anticipated to result from the merger, which would result in the anticipated benefits of the merger not being realized partly or wholly in the time frame currently anticipated or at all;

• lost sales and customers as a result of certain customers of either or both of the two companies deciding not to do business with the combined company, or deciding to decrease their amount of business in order to reduce their reliance on a single company;

• integrating personnel from the two companies while maintaining focus on providing consistent, high quality products and customer service;

• potential unknown liabilities and unforeseen increased expenses, delays or regulatory conditions associated with the merger; and

• performance shortfalls at the combined company as a result of the diversion of management’s attention caused by completing the merger and integrating the companies’ operations.

Business issues currently faced by one company may be imputed to the operations of the other company.

To the extent that either Schlumberger or Smith currently has or is perceived by customers to have operational challenges, such as on-time performance, safety issues or workforce issues, those challenges may raise concerns by existing customers of the other company following the merger, which may limit or impede Schlumberger’s future ability to obtain additional work from those customers.

Failure to retain key employees and skilled workers could adversely affect Schlumberger following the merger.

Schlumberger’s performance following the merger could be adversely affected if the combined company is unable to retain certain key employees and skilled workers of Smith. The loss of the services of one or more of these key employees and skilled workers could adversely affect Schlumberger’s future operating results because of their experience and knowledge of Smith’s business. In addition, current and prospective employees of Schlumberger and Smith may experience uncertainty about their future roles with their company until after the merger is completed. This may adversely affect the ability of both Schlumberger and Smith to attract and retain key personnel.

The required regulatory approvals may not be obtained or may contain materially burdensome conditions that could have an adverse effect on Schlumberger.

Completion of the pending merger is conditioned upon the receipt of certain governmental approvals, including the expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, the issuance by the European Commission of a decision under the EC Merger Regulation declaring the merger compatible with the common market and the approval of the merger by the antitrust regulators in other specified jurisdictions. Although Schlumberger and Smith have agreed in the merger agreement to use their reasonable best efforts to obtain the requisite governmental approvals, there can be no assurance that these approvals will be obtained. In addition, the governmental authorities from which these approvals are required may impose conditions on the completion of the merger or require changes to the terms of the merger. Under the terms of the merger agreement, Schlumberger is required to agree to take all actions

28

demanded by an antitrust regulator in order to resolve any objections to the merger (including divestitures, hold-separate restrictions or other restrictions) if doing so would not exceed a specified threshold, which is referred to as the detriment limit. The detriment limit would be exceeded if the required divestitures or hold-separate restrictions affect assets other than (1) the W-H Energy Services business and corresponding Schlumberger operations and (2) other assets accounting for Schlumberger or Smith revenues of not more than $190 million in 2009, excluding from such calculation any W-H Energy Services operations and Smith’s Wilson business unit. If Schlumberger agrees to undertake divestitures or comply with operating restrictions in order to obtain any approvals required to complete the merger, Schlumberger may be less able to realize anticipated benefits of the merger, and the business and results of operations of the combined company after the merger may be adversely affected.

A significant portion of the combined company’s revenue will be dependent on the activity level of natural gas exploration and production in North America.

Upon consummation of the merger, a larger portion of our revenues will be derived from our North American operations. Because of the current economic environment and related decrease in demand for energy, natural gas exploration and production in North America have decreased significantly from their peak levels in the summer of 2008. Warmer than normal winters in North America, among other factors, may adversely impact demand for natural gas and, therefore, demand for oilfield services. If the economic conditions deteriorate further or do not improve, the decline in natural gas exploration and production could cause a decline in the demand for the services and products of the combined company. Such decline could result in a significant adverse effect on our operating results.

The market value of Schlumberger common stock could decline if large amounts of its common stock are sold following the merger.

Following the merger, stockholders of Schlumberger and former stockholders of Smith will own interests in a combined company operating an expanded business with more assets and a different mix of liabilities. Current stockholders of Schlumberger and Smith may not wish to continue to invest in the combined company, or may wish to reduce their investment in the combined company, in order to comply with institutional investing guidelines, to increase diversification or to track any rebalancing of stock indices in which Schlumberger or Smith common stock is included. If, following the merger, large amounts of Schlumberger common stock are sold, the price of its common stock could decline.

The merger may be dilutive to Schlumberger’s earnings per share in the near term, which may negatively affect the market price of Schlumberger common stock.

The merger may be dilutive to earnings per share in the near term. Future events and conditions could decrease or delay any accretion, result in dilution or cause greater dilution than is currently expected, including:

• adverse changes in energy market conditions;

• commodity prices for oil, natural gas and natural gas liquids;

• production levels;

• reserve levels;

• operating results;

• competitive conditions;

• laws and regulations affecting the energy business;

• capital expenditure obligations; and

• general economic conditions.

29

Any dilution of, or decrease or delay of any accretion to, Schlumberger’s earnings per share could cause the price of Schlumberger’s common stock to decline.

Demand for our products and services could be reduced or eliminated by governmental regulation or a change in the law.

International, national, and state governments and agencies are currently evaluating and promulgating climate-related legislation and regulations that are focused on restricting greenhouse gas (“GHG”) emissions. In the United States, the Environmental Protection Agency (“EPA”) is taking steps to require monitoring and reporting of GHG emissions and to regulate GHGs as pollutants under the Clean Air Act (“CAA”). The EPA’s “Mandatory Reporting of Greenhouse Gases” rule established a comprehensive scheme of regulations that require monitoring and reporting of GHG emissions that began in 2010. Furthermore, the EPA recently proposed additional GHG reporting rules specifically for the oil and gas industry. The EPA has also published a final rule, the “Endangerment Finding”, finding that GHGs in the atmosphere endanger public health and welfare, and that emissions of GHGs from mobile sources cause or contribute to the GHG pollution. Following issuance of the Endangerment Finding, the EPA promulgated final motor vehicle GHG emission standards on April 1, 2010. The EPA has asserted that the final motor vehicle GHG emission standards will trigger construction and operating permit requirements for stationary sources. In addition, climate change legislation is pending in the United States Congress. These developments may curtail production and demand for fossil fuels such as oil and gas in areas of the world where our customers operate and thus adversely affect future demand for our services and products, which may in turn adversely affect future results of operations. Additionally, legislation to reduce greenhouse gases may have an adverse effect on our operations, including payment of additional costs due to carbon emissions. Higher carbon emission activities include transportation, including marine vessels, cement production (by third party suppliers), and electricity generation (by third party suppliers) as well as other activities. Finally, our business could be negatively affected by climate change related physical changes or changes in weather patterns, which could result in damages to or loss of our physical assets, impacts to our ability to conduct operations and/or disruption of our customers’ operations.

Legislation is pending in the United States Congress that would authorize the EPA to regulate hydraulic fracturing under the Safe Drinking Water Act. The legislation would require the reporting and public disclosure of chemicals that could adversely affect drinking water supplies. In addition a number of states are evaluating the adoption of legislation or regulations governing hydraulic fracturing. Such regulations or legislation could reduce demand for pressure pumping services. If federal and/or state legislation or regulations were enacted, it could adversely affect our financial condition, results of operations and cash flows. We are unable to predict whether the proposed legislation, regulations, or any other proposals will ultimately be enacted.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

Unregistered Sales of Equity Securities

During the quarter ended March 31, 2010, Schlumberger issued 565,000 shares of its common stock upon conversion by holders of $22.6 million aggregate principal amount of its 2.125% Series B Convertible Debentures due June 1, 2023. Such shares were issued in transactions exempt from registration under Section 3(a)(9) of the Securities Act of 1933, as amended.

Issuer Repurchases of Equity Securities

On April 17, 2008, the Schlumberger Board of Directors approved an $8 billion share repurchase program for Schlumberger common stock, to be acquired in the open market before December 31, 2011.

30

Schlumberger’s common stock repurchase program activity for the three months ended March 31, 2010 was as follows:

	(Stated in thousands, except per share amounts)
	Total number of shares purchased	Average price paid per share		Total number of shares purchased as part of publicly announced program	Maximum value of shares that may yet be purchased under the program
January 1 through January 31, 2010	400.0	$	65.70	400.0	$	6,539,339
February 1 through February 28, 2010	1,810.8	$	64.10	1,810.8	$	6,423,271
March 1 through March 31, 2010	3,082.0	$	63.24	3,082.0	$	6,228,356
	5,292.8	$	63.72	5,292.8

In connection with the exercise of stock options under Schlumberger’s incentive compensation plans, Schlumberger routinely receives shares of its common stock from optionholders in consideration of the exercise price of the stock options. Schlumberger does not view these transactions as requiring disclosure under this Item as the number of shares of Schlumberger common stock received from optionholders is not material.
