NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)

1. Basis of Presentation

The accompanying unaudited consolidated financial statements 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 Schlumberger management, all adjustments considered necessary for a fair statement have been included in the accompanying unaudited financial statements. All intercompany transactions and balances have been eliminated in consolidation. Operating results for the six-month period ended June 30, 2011 are not necessarily indicative of the results that may be expected for the full year ending December 31, 2011. The December 31, 2010 balance sheet information has been derived from the Schlumberger audited 2010 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, 2010, filed with the Securities and Exchange Commission on February 4, 2011.

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

2. Charges

Schlumberger recorded the following charges during the first six months of 2011 and 2010:

2011

Second quarter of 2011:

	•		Schlumberger made a $50 million grant to the Schlumberger Foundation to support the Foundation’s Faculty for the Future program. This program supports talented women scientists from the developing world by helping them pursue advanced graduate studies in scientific disciplines at leading universities worldwide. This $50 million charge ($40 million after-tax) is classified in General & administrativein the Consolidated Statement of Income.

	•		Schlumberger recorded $32 million of pretax merger and integration-related charges ($24 million after-tax) in connection with the acquisitions of Smith International, Inc. (“Smith”) and Geoservices. This amount is classified in Merger & integration in the Consolidated Statement of Income.

First quarter of 2011:

	•		Schlumberger recorded $34 million of pretax merger and integration-related charges ($28 million after-tax) in connection with the acquisitions of Smith and Geoservices. This amount is classified in Merger & integration in the Consolidated Statement of Income.

			The following is a summary of these charges:


	(Stated in millions)						Consolidated Statement
	Pretax		Tax		Net		of Income Classification
Merger-related integration costs	$	66	$	14	$	52	Merger & integration

	$	116	$	24	$	92

-7-

2010

First quarter of 2010:

	•		Schlumberger incurred $35 million of merger-related costs in connection with the Smith and Geoservices transactions. These costs primarily consisted of legal and other advisory fees.

	•		During March 2010, the Patient Protection and Affordable Care Act (“PPACA”) was signed into law in the United States. Among other things, the PPACA eliminated 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.

			The following is a summary of these charges:


	(Stated in millions)							Consolidated Statement
	Pretax		Tax			Net		of Income Classification
Merger-related transaction costs	$	35	$	—		$	35	Merger & integration

10. 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 derivative transactions for speculative purposes.

Foreign Currency Exchange Rate Risk

As a multinational company, Schlumberger conducts 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 theConsolidated Balance Sheet and in Accumulated Other Comprehensive Loss. Amounts recorded inAccumulated Other Comprehensive 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 hedging instruments, if any, is recorded directly to earnings.

At June 30, 2011, Schlumberger recognized a cumulative net $19 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 June 30, 2011, contracts were outstanding for the US dollar equivalent of $7.3 billion in various foreign currencies.

Commodity Price Risk

Schlumberger is exposed to the impact of market fluctuations in the price of certain commodities, such as metals and fuel. Schlumberger utilizes forward contracts to manage a small percentage of the price risk associated with forecasted metal 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.

At June 30, 2011, $41 million of commodity forward contracts were outstanding.

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 occasionally interest rate swaps to mitigate the exposure to changes in interest rates.

During the third quarter of 2009, Schlumberger entered into an interest rate swap 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 receives interest at a fixed rate of 3.0% annually and pays interest quarterly at a floating rate of three-month LIBOR plus a spread of 0.765%. This interest rate swap is designated as a fair value hedge of the underlying debt. This derivative instrument is marked to market with gains and losses recognized currently in income to offset the respective gains and losses 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 June 30, 2011, Schlumberger had fixed rate debt aggregating $5.6 billion and variable rate debt aggregating $4.0 billion, after taking into account the effects of the interest rate swaps.

Short-term investments and Fixed income investments, held to maturity, totaled $3.9 billion at June 30, 2011, and were comprised primarily of money market funds, eurodollar time deposits, certificates of deposit, commercial paper, euro notes and Eurobonds, and were substantially all denominated in US dollars. The carrying value of these investments approximated fair value, which was estimated using quoted market prices for those or similar investments.

13. 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 governmental authorities and is currently unable to predict the outcome of this matter.

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. Also in 2009, Smith received an administrative subpoena with respect to its historical business practices in certain 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.

On April 20, 2010, a fire and explosion occurred onboard the semisubmersible drilling rig Deepwater Horizon, owned by Transocean Ltd. and under contract to a subsidiary of BP plc. Pursuant to a contract between M-I SWACO and BP, M-I SWACO provided certain services under the direction of BP. A number of legal actions, certain of which name an M-I SWACO entity as a defendant, have been filed in connection with the Deepwater Horizon incident, and additional legal actions may be filed in the future. Based on information currently known, the amount of any potential loss attributable to M-I SWACO with respect to potential liabilities related to the incident would not be material to Schlumberger’s consolidated financial position.

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. Management believes that the probability of a material loss is remote and, as such, that any liability that might ensue would not be material in relation to Schlumberger’s consolidated financial position. However, litigation is inherently uncertain and it is not possible to predict the ultimate disposition of these proceedings.

14. Segment Information

Schlumberger previously reported its results on the basis of five business segments — Schlumberger Oilfield Services, WesternGeco, M-I SWACO, Smith Oilfield and Distribution and by geographical areas within Schlumberger Oilfield Services. As a result of the acquisitions of Smith and Geoservices, the range of Schlumberger’s activities comprising exploration and production services is so broad that it has changed the primary way in which it allocates resources and assesses performance. Consequently, effective with the first quarter of 2011, Schlumberger changed its primary reporting to product group segments (the “Groups”).

The Groups are as follows:

	•		Reservoir Characterization Group — Consists of the principal technologies involved in the finding and defining of hydrocarbon deposits. These include WesternGeco, Wireline, Testing Services, Schlumberger Information Services and Data & Consulting Services.

	•		Drilling Group — Consists of the principal technologies involved in the drilling and positioning of oil and gas wells and is comprised of Bits & Advanced Technologies, M-I SWACO, Geoservices, Drilling and Measurements, Pathfinder, Drilling Tools and Remedial Services, Dynamic Pressure Management and Integrated Project Management (“IPM”) well construction projects.

-15-

•

Reservoir Production Group — Consists of the principal technologies involved in the lifetime production of oil and gas reservoirs and includes Well Services, Completions and Artificial Lift, together with the Subsea and Water and Carbon Services activities and the production activities of IPM.

The Groups are collectively referred to as “Oilfield Services”. Additionally, Schlumberger also reports the Distribution business, acquired in the Smith transaction, as a separate segment.

All prior period segment disclosures have been recast to reflect the new segments.

16. Discontinued Operations

During the second quarter of 2011, Schlumberger completed the divestiture of its Global Connectivity Services business for approximately $385 million in cash. An after-tax gain of $220 million was recognized in connection with this transaction, and is classified in Income from Discontinued Operations in the Consolidated Statement of Income. The historical results of this business were not significant to Schlumberger’s consolidated financial statements and, as such, have not been reclassified to discontinued operations.

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 2 to the Consolidated Financial Statements, interest on postretirement medical benefits, stock-based compensation costs and amortization expense associated with intangible assets recorded as a result of the merger with Smith International Inc. (“Smith”).

OILFIELD SERVICES

Second-quarter results showed strong growth worldwide. Pretax operating income for all Product Groups grew at double-digit rates. In North America, a prolonged Canadian spring break-up and poor weather in the northwest were offset by very strong growth

-18-

in the rest of US land and a significant contribution from deepwater operations as the rig count increased and renewed interest in exploration activity in the Gulf of Mexico led to high multiclient seismic data sales.

Internationally, the trend towards higher deepwater rig count and higher exploration spending continued. This activity was coupled with a surge in development and workover activity as producers moved to compensate for reduced Libya barrels and to profit from higher prices. As a result, all Product Groups had standout product lines in the quarter and technology sales showed good progress. Strong advances were made in all Technologies linked to deepwater exploration and complex development drilling including WesternGeco, Drilling & Measurements, M-I SWACO, and openhole Wireline and Testing services. The Drilling Group continued to record strong synergistic revenue with the legacy Smith Bits and Drilling Tool businesses in many areas of the world. At Reservoir Production, in addition to the strong North American stimulation market, high growth rates were experienced internationally as operators moved to improve production and to test unconventional gas plays in several markets.

Last quarter, Schlumberger anticipated that the international supply response would progressively ramp up over the second half of 2011. It transpired that the international ramp-up made a strong start in the second quarter that Schlumberger believes will continue through the rest of the year and on into 2012.

The continued strength in drilling liquid-rich plays in North America, coupled with an acceleration in drilling both in exploration and development internationally will put considerable strain on the ability of the service industry to meet activity levels. While it is not unprecedented that a North American cycle has run concurrently with increasing activity internationally, the service intensity of drilling and completing horizontal wells in liquid-rich plays and shale gas basins has introduced a new dynamic in as much as this activity requires far more service equipment than was traditionally used in the North American land market. As a result, the ability of the industry to supply both the North American and international markets with the required equipment and people in a concurrent growth phase will be challenged.

Schlumberger, through size, geographical coverage, multinational workforce, comprehensive product and service portfolio and technology capability, believes it is uniquely placed to help its customers meet these challenges worldwide.

Second-quarter revenue of $8.99 billion increased 11% sequentially. Sequentially, revenue increased in all Groups and across all geographical Areas.

Reservoir Characterization revenue increased primarily on higher WesternGeco marine proprietary surveys and multiclient sales, on greater Wireline exploration activity and a partial recovery from the previous quarter’s exceptional weather and geopolitical events, and on increased Schlumberger Information Solutions (SIS) software sales. Drilling revenue increased on higher M-I SWACO activity, and on stronger Drilling & Measurements technology penetration, increased pricing and improved job count. Among the Drilling Technologies, sequential increases were posted by Bits & Advanced Technologies, Drilling Tools & Remedial and Pathfinder. These increases, however, were partially offset by lower Integrated Project Management (IPM) Well Construction in Russia following the sale of the drilling rig business related to the strategic alliance with EDC in the Russia/CIS region. Reservoir Production revenue increased sequentially on higher pricing, capacity additions and improved asset utilization for Well Services in North America but this increase was partially reduced by the effects of the spring break-up in Canada and adverse weather in the Williston basin. Internationally, Well Services grew on stronger activity in the Middle East and Asia Area. Artificial Lift and Completions product sales also grew robustly in the second quarter, particularly in Latin America.

On a geographical basis, North America increased sequentially despite the impact of the spring break-up in Canada and the weather issues in the Williston basin. Higher pricing for Well Services technologies in US land, increasing demand and pricing for M-I SWACO services in unconventional shale plays and the US Gulf of Mexico, higher WesternGeco marine proprietary surveys offshore North America, and strong Drilling Tools & Remedial sales helped propel the percentage revenue increase to double-digit levels. In Latin America, all Groups contributed double-digit sequential growth with significant increases posted by the Venezuela, Trinidad & Tobago; Peru, Colombia & Ecuador; and Brazil GeoMarkets*. Increased WesternGeco revenue, improved Drilling & Measurements exploration activity, increased demand for M-I SWACO services and higher SIS software sales contributed to the increase. In Europe/CIS/Africa, results were driven by higher WesternGeco and M-I SWACO activities and increased exploration activity for Wireline and Testing Services—mainly in the North Sea GeoMarket. This increase, however, was reduced by lower IPM Well Construction in Russia following the sale of the drilling rig business. Middle East & Asia revenue recorded significant double-digit growth across all Groups with increases led by Wireline, Well Services and Drilling & Measurements. Significant expansion was experienced in the Saudi Arabia, Bahrain; Iraq; and East Asia GeoMarkets while the Egypt & East Mediterranean and Australia, Papua New Guinea GeoMarkets recovered from the geopolitical and weather events of the previous quarter.

Second-quarter pretax operating income of $1.75 billion increased 20% sequentially. Pretax operating margin increased 155 basis points (bps) sequentially to 19.5% primarily due to higher WesternGeco marine proprietary surveys and multiclient sales; increased Wireline and Drilling & Measurements exploration activities; higher margin activity for M-I SWACO; higher SIS software sales; and margin improvements in Bits & Advanced Technologies, Drilling Tools & Remedial and Pathfinder.

With respect to Libya, Schlumberger does not expect any return of activity in the short-term due to the ongoing political disturbances. The carrying value of Schlumberger’s assets in Libya was approximately $0.3 billion as of June 30, 2011. This consists primarily of accounts receivable, inventories and fixed assets. Schlumberger’s ability to recover these assets will ultimately depend on how the current situation evolves.

Reservoir Characterization

Second-quarter revenue of $2.46 billion was 12% higher compared to the first quarter of 2011. Pretax operating income of $602 million was 31% higher versus the first quarter of 2011. Pretax operating margins increased 348 bps sequentially to 24.5%.

WesternGeco led the sequential increases with revenue and margins up significantly from higher vessel utilization on proprietary marine surveys. There was also a significant increase in multiclient sales in Brazil, the North Sea and Asia. Wireline revenue and margins expanded on stronger exploration activities in a number of GeoMarkets in Latin America, Africa, the North Sea and Asia and grew on a partial recovery from the previous quarter’s geopolitical and weather issues, particularly in GeoMarkets in North Africa, Middle East and Australia. Deepwater activity rose in the US Gulf of Mexico but this was offset by the seasonal spring break-up in Canada. SIS contributed to the sequential improvements in revenue and margins due to significantly higher software sales across the Areas.

Drilling

Second-quarter revenue of $3.46 billion was 8% higher sequentially. Pretax operating income of $538 million was 15% higher compared to the first quarter of 2011.

Within the Drilling Group, M-I SWACO recorded the largest sequential revenue increase on favorable higher-margin activity in the North Sea and Latin America, on continued growth in unconventional shale plays in North America, on resumption of drilling in the US Gulf of Mexico, and on the increasing recovery in activity in the Middle East and Asia after the previous quarter’s geopolitical and weather events. Drilling & Measurements revenue increased sequentially on higher-margin technology penetration, superior pricing and improved job count mainly in Latin America and Middle East and Asia. Drilling Tools & Remedial increased significantly on higher activity in North America. Pathfinder in US land also reported increased revenue on higher drilling activity in unconventional liquid-rich plays while Bits & Advanced Technologies grew despite the effects of the spring break-up in Canada. IPM Well Construction continued to expand in Iraq as new contracts began and drilling efficiency improved, however, this increase was more than offset by the effect of the sale of the drilling rig business in Russia.

Sequentially, pretax operating margin grew 98 bps to 15.6%. M-I SWACO margins improved with increased high-margin activity in the North Sea GeoMarket, Latin America and US Gulf of Mexico. Drilling & Measurements margins grew due to superior pricing and a more favorable technology mix. Margins also expanded in Bits & Advanced Technologies, Drilling Tools & Remedial, and Pathfinder as service mix and pricing both improved.

Reservoir Production

Second-quarter revenue of $3.06 billion increased 13% sequentially. Pretax operating income of $613 million was 16% higher versus the first quarter of 2011.

Among Reservoir Production Technologies, Well Services revenue expanded sequentially in North America on higher pricing, capacity additions and improved asset utilization as the market transitions to liquid-rich plays on the strength of the oil price. This increase, however, was partially reduced by the spring break-up in Canada and adverse weather in the Williston basin. Internationally, Well Services posted high double-digit growth in the Middle East and Asia Area in the Saudi Arabia, Bahrain; Kuwait; Oman; East Asia; and China GeoMarkets. Completions revenue increased sequentially on higher product sales in Latin America and robust service and product sales in Saudi Arabia. Artificial Lift revenue grew sequentially with all regions contributing to the increase except for Europe/CIS/Africa due to the shutdown in Libya.

Sequentially, second-quarter pretax operating margin increased 57 bps to 20.0%. Excluding the impact of the spring break-up in Canada, Well Services margins grew on pricing gains, better efficiency and utilization of resources in

-20-

North America, and improved performance across the Middle East and Asia due to stronger product sales and services, and higher vessel activity. Artificial Lift margins increased through higher sales on land in North America and Russia.

DISTRIBUTION

Distribution revenue of $637 million increased 6% sequentially. Pretax segment income of $24 million improved 8% sequentially. These increases were primarily driven by strong activity in the shale plays in the US. This growth was offset in part by the impact of the seasonal downturn in Canada.

OILFIELD SERVICES

Second-quarter 2011 revenue of $8.99 billion was 51% higher than the same period last year largely due to the acquisitions of Smith and Geoservices, as well as the significantly improved activity and pricing for Well Services technologies in North America land and higher WesternGeco Marine activity and Multiclient sales. These increases, however, were partially offset by the drawn out impact of political events in Libya and the decrease in activity in Mexico.

On a Product Group basis, Reservoir Characterization revenue increased due to higher WesternGeco Marine activity and Multiclient sales. Drilling revenue increased significantly primarily due to the acquisitions of Smith and Geoservices, partially offset by reduced IPM Well Construction activity. Reservoir Production revenue increased mostly from a combination of higher activity and pricing for Well Services technologies in North America.

Second-quarter 2011 pretax operating margin increased 61 bps to 19.5% as a strong contribution from the increased activity and pricing for Well Services technologies in North America and renewed exploration activity in a number of GeoMarkets were partially offset by the impacts of the Smith and Geoservices acquisitions; political events in Libya; measured recovery of deepwater operations in the US Gulf of Mexico; and the decline in activity in Mexico.

Reservoir Characterization

Second-quarter 2011 revenue of $2.46 billion was 7% higher than the same period last year led by WesternGeco on improved vessel utilization on proprietary marine surveys and higher multiclient sales. SIS also contributed to the year over year increase as a result of significantly higher software sales.

Pretax operating margin increased 38 bps to 24.5% largely due to the improvements of WesternGeco.

Drilling

Second-quarter 2011 revenue of $3.46 billion was 127% higher than the previous year primarily due to the acquisition of Smith and Geoservices.

Year-on-year, pretax operating margin decreased 322 bps to 15.6% primarily due to the impact of the acquisitions and the generally lower pricing for Drilling & Measurements services.

Reservoir Production

Second-quarter 2011 revenue of $3.06 billion increased 47% year-on-year, particularly in North America, due to a mix of capacity additions, better pricing and assets utilization of Well Services Technologies. The addition of certain businesses acquired in the Smith acquisition also contributed to the overall growth.

Year-on-year, pretax operating margin improved 808 basis points to 20.0% mainly due to pricing gains, better efficiency and utilization of resources of Well Services technologies in North America and improved performance across the Middle East and Asia and Latin America due to stronger activity.

OILFIELD SERVICES

Six-month revenue of $17.1 billion increased 48% versus the same period last year due to the acquisitions of Smith in August 2010 and Geoservices in April 2010, as well as the significantly improved activity and pricing for Well Services technologies in North America as the market transitions to liquid-rich plays demanding increasing service intensity in drilling and completing horizontal wells. Internationally, all Areas grew significantly as the trend towards increased deepwater rig count and exploration spending led to higher WesternGeco activity and multiclient seismic data sales and stronger Wireline and Drilling & Measurements exploration activity. However, these increases were tempered by the measured activity recovery in the US Gulf of Mexico and activity disruptions from the first quarter’s exceptional geopolitical unrest in North Africa and the Middle East and weather issues on US land and in Australia.

-23-

On a Product Group basis, Reservoir Characterization revenue increased due to higher WesternGeco Marine activity and Multiclient sales. Drilling revenue increased significantly primarily due to the acquisitions of Smith and Geoservices, partially offset by reduced IPM Well Construction activity. Reservoir Production revenue increased on a combination of higher activity and pricing for Well Services technologies in North America.

Year-to-date Oilfield Services pretax operating margin was flat at 18.7% as the Smith and Geoservices acquisitions were dilutive from a margin perspective while the measured activity recovery in the US Gulf of Mexico and the effects of the exceptional geopolitical events and weather issues that prevailed during the first quarter hampered margin expansion.

Reservoir Characterization

Six-month revenue of $4.65 billion was 2% higher than the same period last year on increased WesternGeco Marine activity and multiclient seismic data sales; on higher SIS software sales; and on moderate Wireline revenue increase as the strength and pricing gains of US land activity and Latin America’s higher exploration activity were offset by the effects of the measured recovery in the US Gulf of Mexico. Testing Services decreased following the effects of the geopolitical events in North Africa and the Middle East as well as the US Gulf of Mexico moratorium.

Year-on-year, pretax operating margin decreased 185 bps to 22.8% led by margin decline in Wireline largely due to the revenue mix as higher North America Land activities were offset by the measured recovery of the US Gulf of Mexico. Testing Services margins fell on the effects of the geopolitical events in North Africa and the Middle East as well as the Gulf of Mexico moratorium. These margin declines were mitigated in part by improved margins in WesternGeco on favorable Multiclient sales mix and increased vessel productivity.

Drilling

Six-month revenue of $6.66 billion was 124% higher than the same period last year primarily due to the Smith International and Geoservices acquisitions.

Year-on-year, pretax operating margin decreased 370 bps to 15.1% largely due to the addition of Smith International and Geoservices activities, measured activity recovery in the US Gulf of Mexico as well as reduced pricing in Drilling & Measurements.

Reservoir Production

Six-month revenue of $5.78 billion was 45% higher than the same period last year while pretax operating margin increased 948 bps to 19.8%. Well Services revenue and margins expanded in North America on higher pricing, capacity additions and improved asset utilization and efficiency as the market transitions to liquid-rich plays on the strength of the oil price. Internationally, Well Services posted growth also on the strength of higher activity despite the exceptional geopolitical events and weather issues that prevailed during the first quarter of 2011.

INTEREST & OTHER INCOME

Interest & other income consisted of the following for the second quarter and six months ended June 30, 2011 and 2010:


					(Stated in millions)
	Second Quarter				Six Months
	2011		2010		2011		2010

Interest income		10		15		19		32

	$	29	$	51	$	60	$	115

The decrease in equity in net earnings of affiliated companies was primarily attributable to the loss of equity earnings from the M-I SWACO joint venture as Schlumberger now owns 100% of this venture following its acquisition of Smith on August 27, 2010.

-24-

OTHER

Research & engineering and General & administrative expenses, as a percentage of Revenue, for the second quarter and six months ended June 30, 2011 and 2010 were as follows:


	Second Quarter				Six Months
	2011		2010		2011		2010

Research & engineering		2.8%		3.6%		2.8%		3.7%
General & administrative		1.4%		1.2%		1.3%		1.3%

Although Research & engineering decreased as a percentage of revenue, in both the second quarter and six months compared to the prior year, it increased in absolute dollars by $58 million and $99 million, respectively. These increases were driven in large part by the impact of the Smith acquisition.

General & administrative increased as a percentage of revenue in both the second quarter and six months compared to the prior year primarily as a result of Schlumberger’s $50 million donation to the Schlumberger Foundation (see discussion of Charges below).

Interest expense for the second quarter of 2011 was $69 million as compared to $53 million for the same period in 2010 and $142 million for the six months ended June 30, 2011 as compared to $99 million for the same period of 2010. These increases were primarily attributable to the issuance during the first quarter 2011 of the $1.1 billion of 4.20% Guaranteed Notes due 2021 and the $500 million of 2.65% Guaranteed Notes due 2016.

The effective tax rate for the second quarter of 2011 was 25.0% compared to 17.8% for the same period in 2010 and 24.5% for the six months ended June 30, 2011 as compared to 20.8% for the same period in 2010. These increases were primarily attributable to the higher proportion of pretax earnings in North America in 2011 as compared to 2010.

Six months ended June 30, 2010	$	871,890		13,734.8	$	63.48

	•		During the first six months of 2011, Schlumberger made contributions of $122 million to its defined benefit pension plans as compared to $130 million during the same period last year.

	•		Cash flow provided by operations was $2.1 billion in the first six months of 2011 compared to $2.3 billion in the first six months of 2010 with the increase in net income offset by an increase in working capital requirements, primarily accounts receivable and inventories, as well as significant tax payments during the first six months of 2011.

	•		Capital expenditures were $1.7 billion in the first six months of 2011 compared to $1.1 billion during the first six months of 2010. Capital expenditures for the full year of 2011 are expected to approach $4.2 billion as compared to $2.9 billion in 2010.

	•		During the first six months of 2010, approximately $320 million of the 2.125% Series B Convertible Debentures due June 1, 2023 were converted by holders into 8.0 million shares of Schlumberger common stock.

As of June 30, 2011 Schlumberger had $4.9 billion of cash and short-term investments on hand. Schlumberger had separate committed debt facility agreements aggregating $5.9 billion with commercial banks, of which $2.8 billion was available and unused as of June 30, 2011. This included $2.3 billion of unused committed facilities which support commercial paper programs 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 had $2.6 billion of commercial paper outstanding as of June 30, 2011.

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.


Item 3.		Defaults Upon Senior Securities.

None.


Item 5.		Other Information.

At Schlumberger’s 2011 Annual General Meeting of Stockholders held on April 6, 2011, Schlumberger’s stockholders voted on, among other matters, a proposal regarding the frequency of future advisory votes on executive compensation (say on pay). As previously reported, a majority of the votes cast on the frequency proposal voted in favor of holding an advisory vote on executive compensation on an annual basis.

Following consideration of the stockholder vote on the frequency proposal, Schlumberger’s Board of Directors decided at a meeting held on July 21, 2011, that Schlumberger will hold an annual advisory vote on executive compensation.
