First quarter of 2010:

	•		Schlumberger incurred $35 million of pretax and after-tax 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.

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 the Consolidated Balance Sheet and in Accumulated Other Comprehensive Loss. Amounts recorded in Accumulated 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 September 30, 2011, Schlumberger recognized a cumulative net $74 million loss 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 September 30, 2011, contracts were outstanding for the US dollar equivalent of $7.4 billion in various foreign currencies.

-12-

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 September 30, 2011, $38 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 3.00% 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 September 30, 2011, Schlumberger had fixed rate debt aggregating $8.0 billion and variable rate debt aggregating $3.4 billion, after taking into account the effects of the interest rate swaps.

Short-term investments and Fixed income investments, held to maturity, totaled $4.6 billion at September 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.

The fair values of outstanding derivative instruments are summarized as follows:

	$	8,740	$	5,517

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.

During the third quarter of 2011 Schlumberger issued $1.1 billion of 1.95% Senior Notes due 2016, $1.6 billion of 3.30% Senior Notes due 2021 and $300 million of Floating Rate Senior Notes due 2014 that bear interest at a rate equal to three-month LIBOR plus 55 basis points per year.

During the first quarter of 2011, Schlumberger repurchased all of the outstanding 9.75% Senior Notes due 2019, the 8.625% Senior Notes due 2014 and the 6.00% Senior Notes due 2016 for approximately $1.26 billion. These transactions did not result in any significant gains or losses.

During the first quarter of 2011, Schlumberger issued $1.1 billion of 4.20% Guaranteed Notes due 2021.

During the first quarter of 2011, Schlumberger issued $500 million of 2.65% Guaranteed Notes due 2016. Schlumberger entered into agreements to swap these dollar notes for euros on the date of issue until maturity, effectively making this a euro denominated debt on which Schlumberger will pay interest in euros at a rate of 2.39%.

-15-

At September 30, 2011, Schlumberger had separate committed debt facility agreements aggregating $5.6 billion with commercial banks, of which $3.4 billion was available and unused. This includes $5.0 billion of committed facilities which support commercial paper programs in the United States and Europe, of which $2.0 billion mature in December 2011 and $3.0 billion mature in July 2016. Interest rates and other terms of borrowing under these lines of credit vary from country to country. Borrowings under the commercial paper programs at September 30, 2011 were $2.0 billion ($1.9 billion at December 31, 2010). At September 30, 2011 all of the commercial paper borrowings were classified within Long-term debt — current portion in the Consolidated Balance Sheet.

The estimated fair value of Schlumberger’s Long-term Debt at September 30, 2011 and December 31, 2010, based on quoted market prices, was $9.0 billion and $5.6 billion, respectively.

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, prior to being acquired by Schlumberger, 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 statements.

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. 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

-17-

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 well construction projects.

	•		*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 Schlumberger Production Management field production projects.

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.

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.

OILFIELD SERVICES

Third-quarter revenue of $9.55 billion increased 6% sequentially. Revenue increased in all Groups and across all geographical Areas with the exception of the Middle East & Asia Area.

On a geographical basis, North America Area revenue increased sequentially following the seasonal rig count recovery in Canada, higher activity on land in the US, and increased deepwater work in the US Gulf of Mexico. All Product Groups registered significant rebounds from the spring break-up in Canada. Reservoir Production, particularly Well Services, posted the highest increase as the rebound was augmented by higher rig count and land activity in the US. Reservoir Characterization and Drilling activities increased from a better mix of key services in the unconventional plays in US land and higher deepwater work in the US Gulf of Mexico. WesternGeco grew on higher Multiclient and Data Processing sales. In the Latin America Area, strong revenue growth was posted in the Mexico GeoMarket* due to higher Integrated Project Management (IPM) well construction project activities on land and on higher Drilling & Measurements work offshore. Argentina grew from strong unconventional gas activities that benefited Well Services. Meanwhile, Brazil experienced strong deepwater and exploration activity that led to expanded Wireline, Testing Services, Drilling & Measurements and M-I SWACO services in the GeoMarket although this was offset by the decline in WesternGeco proprietary marine surveys and multiclient sales. In the Europe/CIS/Africa Area, results were driven by higher revenue in the Continental Europe GeoMarket on a combination of strong drilling activity and fracturing work on unconventional plays in Poland. Russia/Central Asia saw strong land and offshore exploration activity benefiting Wireline, Testing Services, Drilling & Measurements and M-I SWACO Technologies—in addition to the full-quarter effect of the activity increase generated from the strategic alliance formed with the Eurasia Drilling Company Limited. The North Sea GeoMarket grew on higher exploration activity in the UK, Greenland and Denmark. In the Middle East & Asia Area, revenue declined sequentially due to decreased WesternGeco activity. The effect of this was partially mitigated by strong Wireline and Testing Services revenues in the East Asia and China GeoMarkets. Excluding WesternGeco, the Middle East & Asia Area increased sequentially driven by strong drilling and production activity in the Saudi Arabia, Bahrain; Iraq; and East Asia GeoMarkets.

Third-quarter pretax operating income of $1.93 billion increased 10% sequentially. Pretax operating margin increased 77 basis points (bps) sequentially to 20.2% primarily due to increasing higher-margin exploration activities that benefited Wireline, Testing Services, Drilling & Measurements and M-I SWACO. The rebound from the spring break-up in Canada also contributed significantly to margin improvements for Well Services and for all Drilling Group Technologies. These improvements, however, were partially offset by the lower WesternGeco activity during the quarter.

The current financial turmoil has already resulted in a lower outlook for oil demand growth in 2012, although demand is still expected to exceed that of 2011. Recent production data, as well as forward projections indicate that there is a tight cushion of excess oil supply that will continue to support activity. Therefore, while financial turmoil introduces some uncertainty over near-term activity, Schlumberger remains confident that any reductions will be short-lived, and that the outlook for the service industry remains very positive. Schlumberger further believes that its customers’ needs to renew reserves, as evidenced by the recent string of exploration successes particularly in deepwater offshore areas, favors Schlumberger’s broad international footprint. In addition, the balance between our reservoir characterization, drilling and production technologies — both in North America and overseas — will enable us to weather any activity fluctuations.

With respect to Libya, the carrying value of Schlumberger’s assets in the country was approximately $0.3 billion as of September 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

Third-quarter revenue of $2.49 billion was 1% higher compared to the second quarter of 2011. Pretax operating income of $610 million was 1% higher versus the second quarter of 2011.

Wireline and Testing Services posted significant sequential increases with revenue and margins up on stronger offshore exploration activities in Brazil, East Asia, Russia and the North Sea as well as from increased deepwater work in the US Gulf of Mexico. WesternGeco activity decreased, however, from lower marine vessel utilization due to higher transit and docking times while moving between contracts. WesternGeco also declined from reduced land seismic activity while mobilizing crews and equipment in preparation for a large contract survey in the Middle East.

Sequentially, pretax operating margins remained unchanged at 24.5% as significant margin improvements in Wireline and Testing Services from strong exploration activities were largely offset by the margin declines in WesternGeco.

-22-

Drilling

Third-quarter revenue of $3.68 billion was 6% higher sequentially. Pretax operating income of $613 million increased 14% over the prior quarter.

Among Drilling Group Technologies, M-I SWACO recorded the largest sequential revenue increase through continued growth in unconventional shale plays on land in the US with higher asset utilization, as well as from the seasonal rig count recovery in Canada and Russia, and the increased deepwater activity in the US Gulf of Mexico and Brazil. Drilling & Measurements revenue increased sequentially on the strong summer drilling campaign in Russia and stronger deepwater activities in the US Gulf of Mexico and Brazil and increased shelf activity in Mexico. Pathfinder reported increased revenue from a more favorable technology mix on land in the US. In addition, Pathfinder, Geoservices and Bits & Advanced Technologies registered activity rebounds following the spring break-up in Canada.

Sequentially, pretax operating margins grew 111 bps to 16.7% driven by the rebound in activity in Canada, an improved technology mix, and further integration and expansion of Smith and Schlumberger drilling technologies. Bits & Advanced Technologies contributed to this improvement with increased sales and rentals of higher-margin drill bits while Pathfinder improved on higher-technology integration with Drilling & Measurements. M-I SWACO margins improved through increased exploration activities in the US Gulf of Mexico, Russia and Brazil, as well as through the seasonal rig count recovery in Canada. Better pricing on IPM land projects in Mexico and improved efficiencies on a well construction project in Algeria further contributed to this result.

Reservoir Production

Third-quarter revenue of $3.37 billion increased 10% sequentially. Pretax operating income of $707 million was 16% higher sequentially.

Among Reservoir Production Group Technologies, Well Services sequential revenue growth in North America was driven by the rebound from the spring break-up in Canada, stronger activity in liquids-rich unconventional plays, capacity additions and continuing improvements in asset utilization. Internationally, Well Services posted high double-digit growth in Latin America from higher stimulation and coiled-tubing activities in Argentina, Mexico, Venezuela and Brazil. Europe/CIS/Africa increased significantly from shale fracturing services in Poland, increased deepwater cementing work in the Black Sea, and strong land activities in Russia. In addition, strong stimulation vessel activity was seen in the Nigeria and the Gulf of Guinea Africa GeoMarket. Artificial Lift revenue grew sequentially across all Areas led by the North America and the Middle East & Asia Areas.

Sequentially, third-quarter pretax operating margins increased 96 bps to 21.0% as Well Services activity in Canada rebounded following the end of the spring break-up. In addition, Well Services achieved better cost efficiency and asset utilization on land in the US and in Russia and recorded increased higher-margin stimulation activities in the Europe/CIS/Africa Area.

DISTRIBUTION

Distribution revenue of $698 million increased 10% sequentially. Pretax segment income of $31 million improved 28% sequentially. These increases were primarily driven by strong activity in the shale plays in the US and the seasonal improvement in Canada.

OILFIELD SERVICES

Third-quarter 2011 revenue of $9.55 billion was 44% higher than the same period last year largely due to the acquisition of Smith on August 27, 2010, as well as to the significantly improved activity of Well Services technologies in North America and an increase in Wireline and Drilling & Measurements exploration activities in a number of GeoMarkets.

Third-quarter 2011 pretax operating margin increased 190 bps to 20.2% primarily due to strong contribution from Well Services Technologies, particularly in North America, as a result of increased capacity and improved efficiency, higher-margin exploration activities that benefited Wireline and to improvements at WesternGeco.

-24-

Reservoir Characterization

Third-quarter 2011 revenue of $2.49 billion was 9% higher than the same period last year led by Wireline in North America, where offshore revenues improved considerably following the resumption of activity in the US Gulf of Mexico combined with a strong performance on land. Testing Services and Schlumberger Information Solutions also increased, mainly in the Latin America and Europe/CIS/Africa Areas, while WesternGeco was higher as improved multiclient sales more than offset the drop in land seismic revenues.

Pretax operating margin increased 151 bps to 24.5% largely due to the higher-margin exploration activities that benefited Wireline and improvements at WesternGeco.

Drilling

Third-quarter 2011 revenue of $3.68 billion was 79% higher than the previous year primarily due to the fact that the comparable period in the prior year only reflected one month of activity from the acquired Smith businesses following the closing of the transaction on August 27, 2010. Additionally, Drilling and Measurements revenue increased on higher activity across most Areas, most notably in North America as a result of the resumption of activity in the US Gulf of Mexico.

Year-on-year, pretax operating margin increased 167 bps to 16.7% largely due to improved pricing and operating efficiencies on IPM projects in Mexico and Algeria.

Reservoir Production

Third-quarter 2011 revenue of $3.37 billion increased 47% year-on-year, particularly in North America, due to a combination of capacity additions and continuing improvements in asset utilization of Well Services Technologies. Well Services also posted significant growth internationally. The addition of Production Wireline and Completion Systems, both acquired Smith businesses, also contributed to the Group’s growth as did Artificial Lift, which increased on strong growth in Latin America, on land in the US and in Russia.

Year-on-year, pretax operating margin improved 453 bps to 21.0% mainly due to the strong performance of Well Services technologies in North America.

DISTRIBUTION

Third-quarter 2011 revenue of $698 million increased $499 million, while pretax operating income of $31 million increased $22 million compared to the same period last year. These increases are attributable to the fact that the third quarter of 2010 included only one month of post-merger activity following the Smith acquisition on August 27, 2010.

OILFIELD SERVICES

Nine-month revenue of $26.7 billion increased 47% versus the same period last year due to the acquisitions of Smith in August 2010 and Geoservices in April 2010, as well as to the significantly improved activity, pricing and asset efficiency 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 deepwater and exploration activity continued to strengthen with early signs of pricing traction for Wireline and Drilling & Measurements. The resumption of activity in the US Gulf of Mexico and higher WesternGeco marine and multiclient sales also contributed to the increase. However, these increases were tempered by activity disruptions from the first quarter’s geopolitical unrest in North Africa and the Middle East.

Year-to-date pretax operating margin increased 71 basis points to 19.3% primarily due to the resumption of higher-margin activity in the US Gulf of Mexico and to the improved pricing and asset efficiency for Well Services Technologies in North America. However the margin expansion was hampered by the effects of the geopolitical events.

Reservoir Characterization

Nine-month revenue of $7.14 billion was 5% higher than the same period last year on stronger Wireline activity, higher WesternGeco marine and multiclient sales and increased Schlumberger Information Solutions software sales.

Year-on-year, pretax operating margin decreased 71 bps to 23.4% led by margin declines in Wireline and Testing Services, largely due to the revenue mix and the impact of the geopolitical events that prevailed during the first quarter. The margin decline however was partially offset by a favorable WesternGeco multiclient sales mix and improved marine vessel utilization.

Drilling

Nine-month revenue of $10.34 billion was 106% higher than the same period last year primarily due to the Smith and Geoservices acquisitions.

Year-on-year, pretax operating margin decreased 160 bps to 15.7% largely due to the addition of Smith and Geoservices activities and the effects of the geopolitical events that prevailed during the first quarter.

Reservoir Production

Nine-month revenue of $9.15 billion was 46% higher than the same period last year while pretax operating margin increased 767 bps to 20.2%. Well Services revenue and margins expanded largely in North America on higher pricing, capacity additions and improved asset utilization and efficiency as the market transitions to liquid-rich plays.

-26-

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.

DISTRIBUTION

Nine-month revenue of $1.94 billion increased $1.74 billion, while pretax operating income of $77 million increased $68 million compared to the same period last year. These increases are attributable to the fact that the nine months ended September 30, of 2010 included only one month of post-merger activity following the Smith acquisition on August 27, 2010.

INTEREST & OTHER INCOME

Interest & other income consisted of the following for the third quarter and nine months ended September 30, 2011 and 2010:


						(Stated in millions)
	Third Quarter					Nine Months
	2011		2010			2011		2010
Equity in net earnings of affiliated companies	$	24	$	46		$	65	$	129
Interest income		10		12			29		44
Other		—		(4	)		—		(4	)

	$	34	$	54		$	94	$	169

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 the acquisition of Smith on August 27, 2010.

OTHER

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


	Third Quarter						Nine Months
	2011			2010			2011			2010
Research & engineering		2.6	%		3.5	%		2.8	%		3.6	%
General & administrative		0.9	%		1.1	%		1.1	%		1.2	%

Although Research & engineering decreased as a percentage of revenue, in both the third quarter and nine months compared to the prior year, it increased in absolute dollars by $26 million and $138 million, respectively. These increases were driven in large part by the impact of the Smith acquisition.

Interest expense for the third quarter of 2011 was $70 million as compared to $47 million for the same period in 2010 and $212 million for the nine months ended September 30, 2011 as compared to $146 million for the same period of 2010. These increases were primarily attributable to the $4.6 billion of long-term debt that Schlumberger issued during the first nine months of 2011.

The effective tax rate for the third quarter of 2011 was 23.8% compared to 10.8% for the same period in 2010, which was significantly impacted by the charges and credits described in Note 2 to the Consolidated Financial Statements. Excluding the impact of these charges and credits, the effective tax rate for the third quarter of 2010 was 21.0%. The year-on-year increase in the effective tax rate, excluding the impact of the third quarter 2010 charges and credits, was primarily attributable to the fact that Schlumberger generated a larger proportion of its pretax earnings in North America in the third quarter of 2011.

The effective tax rate for the nine months ended September 30, 2011 was 24.2% compared to 15.7% for the same period of the prior year which was also significantly impacted by the charges and credits described in Note 2 to the Consolidated Financial Statements. Excluding the impact of these charges and credits, the effective tax rate for the nine months ended September 30, 2010 was 19.3%. The increase in the effective tax rate, excluding the impact of the 2010 charges and credits, was primarily attributable to the fact that Schlumberger generated a larger proportion of its pretax earnings in North America in 2011 as compared to 2010.

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 expectations regarding business outlook; growth for Schlumberger as a whole and for each of its segments (and for specified products or geographic areas within each segment); oil and natural gas demand and production growth; oil and natural gas prices; operating margins; improvements in operating procedures and technology; capital expenditures by Schlumberger and the oil and gas industry; the business strategies of Schlumberger’s customers; future global political and economic conditions; and future results of operations. These statements are subject to risks and uncertainties, including, but not limited to, current global economic conditions; 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, geopolitical and business conditions in key regions of the world; pricing erosion; weather and seasonal factors; the ability to respond to increased activity levels; changes in government regulations and regulatory requirements, including those related to offshore oil and gas exploration, radioactive sources, explosives, chemicals, hydraulic fracturing services and climate-related initiatives; continuing operational delays or program reductions as of result of the lifted drilling moratorium in the Gulf of Mexico; inability of technology to meet new challenges in explorations; and other risks and uncertainties detailed in 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 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.
