3.	Charges and Credits

2006

Second quarter of 2006:

•

Schlumberger acquired the 30% minority interest in WesternGeco held by Baker Hughes Incorporated for $2.4 billion in cash during the second quarter of 2006. In connection with this transaction, a pretax and after-tax charge of $21 million was recorded, representing the portion of the purchase price that was allocated to in-process research and development. Schlumberger recorded an additional $6 million of in-process research and development charges, primarily related to a small acquisition which was also completed in the second quarter of 2006. These amounts were determined by identifying research and development projects that had not yet reached technological feasibility at the time of the acquisition. These charges are classified in Research & engineering in the Consolidated Statement of Income.

•

Schlumberger recorded a pretax and after-tax loss of $9 million relating to the liquidation of certain investments in connection with the funding of the previously mentioned WesternGeco transaction. These losses are classified in Interest & other income in the Consolidated Statement of Income.

•

In connection with the settlement of the WesternGeco visa matter described in Note 13, a pretax charge of $10 million ($7 million after-tax and minority interest) was recorded and is classified in Cost of goods sold & services in the Consolidated Statement of Income.

The Schlumberger joint venture agreement with Smith International, Inc. contains a provision under which either party to the joint venture may offer to sell their entire interest in the venture to the other party at a cash purchase price per percentage interest specified in an offer notice. If the offer to sell is not accepted, the offering party will be obligated to purchase the entire interest of the other party at the same price per percentage interest as the price specified in the offer notice.

In July 2006, the Financial Accounting Standards Board (FASB) issued FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes – an Interpretation of FASB Statement No. 109 (FIN 48), which clarifies the accounting for uncertain tax positions. This interpretation requires companies to recognize in their financial statements the impact of a tax position, if that position is more likely than not of being sustained on audit, based on the technical merits of the position. Schlumberger adopted the provisions of FIN 48 effective January 1, 2007. The adoption of FIN 48 did not have any impact on the total liabilities or stockholders’ equity of Schlumberger.

Included in the Schlumberger Consolidated Balance Sheet at January 1, 2007 is approximately $764 million of liabilities associated with uncertain tax positions in the over 100 jurisdictions in which Schlumberger conducts business. This amount includes $94 million of accrued interest and penalties. Approximately $739 million of unrecognized tax benefits, if recognized, would impact the Schlumberger effective tax rate.

Schlumberger classifies interest and penalties relating to uncertain tax positions within Taxes on income in the Consolidated Statement of Income.

The following table summarizes the tax years that are either currently under audit or remain open and subject to examination by the tax authorities in the most significant jurisdictions in which Schlumberger operates:


Canada		2002 - 2006
Mexico		2002 - 2006
Russia		2004 - 2006
Saudi Arabia		2001 - 2006
United Kingdom		2004 - 2006
United States		2003 - 2006

In certain of the jurisdictions noted above, Schlumberger operates through more than one legal entity, each of which has different open years subject to examination. The table above presents the open years subject to examination for the most material of the legal entities in each jurisdiction. Additionally, it is important to note that years are technically not closed until the statute of limitations in each jurisdiction expires. In the jurisdictions noted above, the statute of limitations can extend beyond the open years subject to examination.

Due to the breadth of the operations of Schlumberger, numerous tax audits may be ongoing throughout the world at any point in time. Tax liabilities are recorded based on estimates of additional taxes which will be due upon the conclusion of these audits. Estimates of these tax liabilities are made based upon prior experience and are updated in light of changes in facts and circumstances. However, due to the uncertain and complex application of tax regulations, it is possible that the ultimate resolution of audits may result in liabilities which could be materially different from these estimates.

13.

Contingencies

The Consolidated Balance Sheet includes accruals for estimated future expenditures, relating to contractual obligations associated with business divestitures that have been completed. It is possible that the ultimate expenditures may differ from the amounts recorded. In the opinion of management, such differences are not expected to be material relative to Schlumberger’s consolidated liquidity, financial position or future results of operations.

In July 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 conducting its own investigation with respect to these services.

In December 2004, WesternGeco L.L.C. and Schlumberger Technology Corporation received federal grand jury subpoenas issued by the United States District Court for the Southern District of Texas. The subpoenas sought documents relating to possible fraud in obtaining visas for foreign crewmembers working on vessels operating on the Outer Continental Shelf of the Gulf of Mexico. On June 16, 2006, WesternGeco L.L.C. entered into an agreement with the United States Attorney’s Office for the Southern District of Texas resolving the issues raised in the federal investigation. Under the terms of the agreement, WesternGeco L.L.C. accepted responsibility for U.S. visa violations and agreed to pay a monetary penalty of $18 million and reimburse the United States Government for $1.6 million in investigation expenses. Additionally, WesternGeco L.L.C. entered into a twelve-month Deferred Prosecution Agreement (“DPA”), during which time its Gulf of Mexico activities were subject to

SCHLUMBERGER LIMITED

and Subsidiary Companies

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

(Unaudited)

monitoring by the United States Government. At the conclusion of this twelve-month period on June 16, 2007, WesternGeco L.L.C. was determined to have complied with the terms of the DPA. As a result, the DPA expired and no prosecution arising from the investigation will be brought. Moreover, WesternGeco has developed and implemented a comprehensive visa and immigration compliance program designed to prevent a recurrence of improper visa practices.

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 presently 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, no liability that might ensue would be material in relation to Schlumberger’s consolidated liquidity, financial position or future results of operations.

Pretax operating income represents the business segments’ income before taxes and minority interest. The pretax operating income excludes corporate expenses, interest income, interest expense, amortization of certain intangible assets, interest on postretirement medical benefits and stock-based compensation costs and the Charges and Credits described in detail in Note 3 to the Consolidated Financial Statements, as these items are not allocated to the segments.

Third Quarter 2007 Compared to Third Quarter 2006

Revenue for the third quarter of 2007 was $5.93 billion versus $4.95 billion for the same period last year. Income before income taxes and minority interest was $1.71 billion for the three-month period ending September 30, 2007 compared to $1.32 billion for 2006.

OILFIELD SERVICES

Oilfield Services revenue of $5.13 billion increased 3% sequentially and 19% year-on-year.

Pretax operating income of $1.51 billion was essentially flat sequentially, but increased 23% year-on-year. Sequentially, growth through stronger demand for Well Services and Wireline technologies in Canada; a more favorable activity mix in the Mexico/Central America GeoMarket; higher activity levels and a favorable technology mix in Peru/Colombia/Ecuador; and increased high-margin Drilling & Measurements activity in China/Japan/Korea and Eastern Russia was experienced. However, this growth was offset by the weather-related effects in the US Gulf of Mexico and the pressure-pumping pricing erosion on land in the US. The overall Oilfield Services pretax operating margin was 29.4%, a sequential decrease of 107 basis points.

Year-on-year growth for both revenue and pretax operating income was driven by higher activity in Latin America, followed by the Middle East & Asia and Europe/CIS/Africa Areas. This growth was partially offset by a decline in North America.

North America

Revenue of $1.30 billion decreased 3% sequentially and 3% year-on-year. Pretax operating income of $350 million decreased 16% sequentially and 15% year-on-year.

Sequentially, revenue in the Canada GeoMarket rebounded on the higher rig count led by demand for Well Services and Wireline technologies following the seasonal spring break-up. However, this growth was more than

offset by a slowdown in the US Gulf Coast due to operator caution during the hurricane season; lower exploration-driven activity associated with seasonal facilities and rig maintenance in Alaska; and the pricing erosion in pressure-pumping stimulation services in all three US land GeoMarkets.

Year-on-year revenue increases were registered in the US Land Central GeoMarket driven by higher rig count and increased demand for Drilling & Measurements technologies; in US Land North resulting from higher rig count; and in Alaska driven by higher demand for new technology applications. However, these increases were more than offset by a decline in rig count in Canada, lower rig count and operator caution during the hurricane season in the US Gulf Coast, together with lower activity in US Land West.

Pretax operating margin for the Area declined 427 basis points sequentially to 26.9% primarily due to the weather-related effects on activity in the US, particularly in the Gulf of Mexico; lower high-margin exploration activity in Alaska; and the lower pricing environment for pressure-pumping stimulation services in the US land GeoMarkets. In Canada, however, margins grew as a result of improved utilization of people and equipment as activity rebounded.

Pretax operating margin reduced year-on-year by 360 basis points. During the period, an improvement in margins in Alaska was more than offset by a decline in the US land GeoMarkets together with a decline in the US Gulf Coast and in Canada.

Latin America

Revenue of $863 million increased 13% sequentially and 37% year-on-year. Pretax operating income of $204 million increased 14% sequentially and 58% year-on-year.

Sequential revenue growth was primarily driven by a continuing ramp-up in Integrated Project Management (IPM) activity in Mexico/Central America. A higher rig count coupled with stronger demand for Drilling & Measurements, Artificial Lift Systems and Schlumberger Information Solutions technologies in the Peru/Colombia/Ecuador GeoMarket also contributed to growth.

Year-on-year revenue growth in the Area resulted from higher activity in IPM projects in Mexico/Central America, together with higher rig counts in the Peru/Colombia/Ecuador and Venezuela/Trinidad & Tobago GeoMarkets. In addition, Latin America South also contributed to growth through increases in exploration-related activities.

Sequentially, pretax operating margin increased by 10 basis points to 23.7% as a result of an increase in exploration-related higher-margin Drilling & Measurements services in Peru/Colombia/Ecuador and a more favorable activity mix on IPM projects in Mexico/Central America.

Pretax operating margin increased year-on-year by 307 basis points, driven by demand for higher-margin services in Peru/Colombia/Ecuador and Latin America South, and an improved activity mix in the Mexico/Central America and Venezuela/Trinidad & Tobago GeoMarkets.

Europe/CIS/Africa

Revenue of $1.69 billion increased 5% sequentially and 28% year-on-year. Pretax operating income of $495 million increased 7% sequentially and 38% year-on-year.

Sequential revenue growth was driven by seasonally higher activity levels on land and offshore in the East Russia GeoMarket; increased demand for IPM services and for Artificial Lift Systems products in South Russia; higher demand for Drilling & Measurements technologies in North Russia; and the impact of the consolidation of Tyumenpromgeofizika. Increased demand for Well Services and Drilling & Measurements technologies in North Africa; higher demand for Artificial Lift Systems products in Continental Europe; and stronger demand for

Wireline and Well Testing technologies in West and South Africa also contributed to growth. However, this was partially offset by project slowdowns in Nigeria and the Caspian, and by lower activity in Libya.

Year-on-year revenue growth in the Area was driven by higher rig count and increased demand for Well Services and Drilling & Measurements technologies in North Africa; higher demand for Drilling & Measurements technologies in North Russia, increased demand for Artificial Lift Systems products in South Russia together with the impact of the consolidation of Tyumenpromgeofizika. Increased exploration-driven activity in the North Sea, Continental Europe and West and South Africa and higher rig count in Libya also contributed to growth.

The Area pretax operating margin increased by 50 basis points sequentially to reach 29.2% driven primarily by increased demand for higher-margin Well Services and Drilling & Measurements technologies in North Africa and a more favorable activity mix in the Russia GeoMarkets. This performance was partially offset by the project slowdowns in Nigeria and the Caspian and by lower demand for higher-margin Wireline and Drilling & Measurements technologies in Libya.

Pretax operating margin increased year-on-year by 218 basis points as a result of efficiency gains in IPM projects across Russia, demand for higher-margin exploration related services in the North Sea, Continental Europe and West & South Africa GeoMarkets, and a favorable activity mix in North Africa. This increase was partially offset by pricing erosion in Libya.

Middle East & Asia

Revenue of $1.23 billion increased 1% sequentially and 28% year-on-year. Pretax operating income of $438 million increased 2% sequentially and 42% year-on-year.

The sequential growth in revenue resulted from higher activity in the China/Japan/Korea, Indonesia, Australia/Papua New Guinea, India, Brunei/Malaysia/Philippines and Gulf GeoMarkets. This growth was partially offset by lower activity in Qatar and Thailand/Vietnam.

The year-on-year revenue increased from higher demand for Drilling & Measurements and Wireline technologies together with increased Completions and Artificial Lift Systems product sales in Australia/Papua New Guinea; higher land activity in China/Japan/Korea; higher rig count in India; higher rig count and increased demand for Drilling & Measurements technologies in Qatar; and higher demand for Well Testing services in Brunei/Malaysia/Philippines. In addition, revenue increases were also recorded in the East Mediterranean with strong demand for IPM and Wireline technologies, and in the Arabian and Indonesia GeoMarkets driven by higher demand for Well Services technologies.

Pretax operating margin increased by 39 basis points sequentially to 35.7% driven by the activity mix in China/Japan/Korea; increased demand for higher-margin Drilling & Measurements and Well Testing technologies in Australia/Papua New Guinea; and higher demand for Wireline and Well Testing technologies in Brunei/Malaysia/Philippines. This performance was partially offset by the slowdown in the Thailand/Vietnam GeoMarket.

Pretax operating margin increased by 353 basis points year-on-year driven by exploration-related higher-margin activities in the Australia/Papua New Guinea, Eastern Mediterranean and China/Japan/Korea GeoMarkets, an increased demand for high-margin Wireline and Drilling & Measurements technologies in the Gulf and Qatar GeoMarkets, together with an increased demand for high-margin Well Services technologies in Indonesia.

WESTERNGECO

Third-quarter revenue of $794 million increased 19% sequentially and was 20% higher compared to the same period last year. Pretax operating income of $306 million increased 42% sequentially and 32% year-on-year.

Sequentially, Marine revenue increased due to higher vessel utilization following seasonal transits and scheduled dry dock inspections in the prior quarter, full-quarter utilization of the seventh Q* vessel, and improved pricing for conventional and Q-Marine* surveys. Data Processing revenue also increased driven primarily by higher sales in Europe, North America and Asia. These increases were partially offset by lower Multiclient sales while Land activity was flat.

Year-on-year Marine revenue increased primarily due to significantly higher pricing on both Q and conventional surveys. Data Processing revenue increased driven by higher demand and better pricing across all regions. In addition, Land revenue increased due to higher demand in the Middle East, North Africa and Latin America. These increases were partially offset by lower Multiclient sales in North America.

Pretax operating margins increased sequentially by 611 basis points to reach 38.6% driven by higher operating leverage in Marine and higher-margin Data Processing activities.

Increase in pretax income year-on-year was led by higher operating leverage in Marine and increased efficiency in Data Processing. However, these increases were partially offset by lower demand for Multiclient sales while Land activity remained essentially flat.

Nine Months 2007 Compared to Nine Months 2006

Revenue for the nine-month period ended September 30, 2007 was $17.03 billion versus $13.88 billion for the same period last year. Income before income taxes and minority interest was $4.88 billion for the nine-month period ended September 30, 2007 compared to $3.48 billion for the nine-month period ended September 30, 2006. The 2006 results included pretax charges of $46 million. These Charges and Credits are described in detail in Note 3 to the Consolidated Financial Statements.

OILFIELD SERVICES

Nine-month revenue of $14.86 billion increased 22% year-on-year. Pretax operating income of $4.42 billion increased 33% year-on-year. Year-on-year revenue growth was strongest in the Australia/Papua New Guinea, Thailand/Vietnam, Qatar, North Africa, West & South Africa, and East Mediterranean GeoMarkets. In addition, double-digit growth was achieved in all Technologies.

North America

Revenue of $4.01 billion increased 5% year-on-year and pretax operating income of $1.20 billion increased 3% versus the same period last year. Year-on-year growth was driven by a strong exploration season in Alaska, and by increased application of higher-margin Drilling & Measurements technologies and Well Testing services in the deep-water environment of the US Gulf Coast. In addition, US Land North grew on rig count increases promoting robust Wireline open hole and Well Services activities, while growth in US Land Central was driven by an increased volume of horizontal well drilling in unconventional gas plays. This was partially offset by declines in Canada with an extended spring break-up period together with the effect of weak gas prices.

Latin America

Revenue of $2.35 billion was 25% higher year-on-year. Pretax operating income of $546 million increased 54% versus the same period last year. Increases were highest in Venezuela/Trinidad & Tobago with strong demand for Drilling & Measurements technologies, Well Testing services, increased Completion and Artificial Lift product sales, and the recognition of revenues related to the drilling barges projects. Strong growth was also generated in Mexico/Central America with higher demand for Well Services and Drilling & Measurements technologies associated with IPM projects. Peru/Colombia/Ecuador increased on a higher exploration activity together with

strong performance on IPM projects and further enhanced by Artificial Lift Systems product sales. Growth in Latin America South was driven by rising offshore exploration activity in Brazil.

Europe/CIS/Africa

Revenue of $4.82 billion increased 33% year-on-year. Pretax operating income of $1.39 billion increased 53% year-on-year. Growth in the Area was driven by rising offshore activity with higher application of premium technologies in North Africa; higher rig count and improved activity mix together with pricing gains in West & South Africa; increased exploration activity in Continental Europe; and higher IPM activity across Russia together with the impact of the consolidation of Tyumenpromgeofizika. In addition, growth was also recorded in the North Sea and Nigeria GeoMarkets. Year-on-year double-digit growth was achieved across all Technologies.

Middle East & Asia

Revenue of $3.53 billion was 31% higher year-on-year. Pretax operating income of $1.24 billion was 45% higher versus the same period last year. Growth in the Area resulted from higher activity, an improved technology mix together with higher Completions product sales in Australia/Papua New Guinea; exploration-driven demand for services in Thailand/Vietnam and Qatar; higher demand for Well Services and Wireline technologies in East Mediterranean; and increased rig count together with higher demand for Drilling & Measurements services and Completions systems product sales in India. In addition, higher rig count together with stronger demand for Artificial Lift Systems and Completions products in the Arabian GeoMarket together with exploration-driven activity growth in China/Japan/Korea and the Gulf GeoMarkets contributed to this growth. Across the Area, all Technologies recorded double digit growth.

WESTERNGECO

Nine-month revenue of $2.17 billion was 23% higher compared to the same period last year. Pretax income of $788 million increased 43% year-on-year. Growth was driven primarily by higher conventional and Q-Marine pricing and by the addition of the seventh Q vessel, higher Multiclient sales predominantly in North America together with higher pricing and increased demand for Data Processing services.

Interest & Other Income

Interest & other income consisted of the following for the third quarter and nine months ended September 30, 2007 and 2006:


	Third Quarter				Nine Months
	2007		2006		2007		2006

Interest Income

Interest income increased $19 million in the third quarter of 2007 as compared to the third quarter of 2006 and by $24 million for the nine months ended September 30, 2007 as compared to the same period last year. These increases were primarily attributable to increases in the average investment balances year-on-year.

Equity in Net Earnings of Affiliated Companies

The increase in net earnings of affiliated companies is primarily due to the results of the drilling fluids joint venture that Schlumberger operates with Smith International, Inc.

Interest Expense

Interest expense of $69 million in the third quarter of 2007 increased by $6 million compared to the same period last year and by $31 million in the first nine months of 2007 compared to the same period last year. The increases were primarily attributable to the increases in the average debt balance year-on-year.

Other

Gross margin was 34.1% and 32.2% in the third quarter of 2007 and 2006, respectively, and 33.9% and 30.8% in the nine-month periods ended September 30, 2007 and 2006, respectively. The increase in gross margin was driven by higher overall activity, a favorable technology mix and efficiency gains in Oilfield Services, together with higher Marine pricing and utilization in WesternGeco.

As a percentage of revenue, research & engineering, marketing and general & administrative expenses for the third quarter and nine months ended September 30, 2007 and 2006 were as follows:


	Third Quarter				Nine Months
	2007		2006		2007		2006
Research & engineering	3.2	%	3.0	%	3.1	%	3.2	%
Marketing	0.4	%	0.4	%	0.3	%	0.4	%
General & administrative	2.3	%	2.4	%	2.2	%	2.3	%

Research and engineering expenditures, by business segment for the third quarter and nine months ended September 30, 2007 and 2006, were as follows:


	Third Quarter				Nine Months
	2007		2006		2007		2006
	(Stated in millions)
Oilfield Services	$	151	$	128	$	429	$	368
WesternGeco		36		20		91		51
Other		3		2		12		31

	$	190	$	150	$	532	$	450

The effective tax rate in the third quarter of 2007 was 20.8% compared to 24.1% in the third quarter of 2006. The effective tax rate for the nine months ended September 30, 2007 was 22.3% compared to 24.5% in the same period of 2006. The decreases in the effective tax rate compared to prior year periods were primarily attributable to the geographic mix of earnings. Both Oilfield Services and WesternGeco had a lower proportion of pretax earnings in North America. Outside North America, various GeoMarkets with lower tax rates contributed a greater percentage to pretax earnings.

Minority Interest

Minority interest decreased in 2007 compared to 2006 reflecting the acquisition, on April 28, 2006, of the 30% minority interest in WesternGeco from Baker Hughes Incorporated.

Stock-Based Compensation

Stock-based compensation expense was $32 million in the third quarter of 2007 compared to $30 million in the third quarter of the prior year, and $102 million for the nine months ended September 30, 2007 compared to $84

million for the nine months ended September 30, 2006. Total stock-based compensation expense for all of fiscal 2006 was $114 million, and it is currently estimated to be $135 million in 2007.

During the first nine months of 2007, $483 million of the $975 million 1.5% Series A Convertible Debentures due June 1, 2023 were converted by holders into approximately 13 million shares of Schlumberger common stock and $7 million of the $450 million 2.125% Series B Convertible Debentures due June 1, 2023 were converted by holders into approximately 175,000 shares of Schlumberger common stock.

During the first nine months of 2007, cash provided by operations was $4.11 billion, as net income plus non-cash items were partially offset by an increase in working capital requirements. Cash used by investing activities was $3.05 billion due mainly to the purchase of fixed assets ($2.01 billion). Cash used by financing activities was

$1.07 billion as the net repayments of debt ($308 million), payment of dividends to shareholders ($562 million) and stock repurchase program ($798 million) were partially offset by the proceeds from employee stock plans ($521 million).

On April 28, 2006, Schlumberger acquired the 30% minority interest in WesternGeco from Baker Hughes Incorporated for $2.4 billion in cash. Approximately 50% of the purchase price was funded from Schlumberger cash and investments. The remaining 50% was financed through existing Schlumberger credit facilities.

During the first nine months of 2006, cash provided by operations was $3.12 billion, as net income, depreciation/amortization and deferred income taxes were partially offset by increases in customer receivables and a decrease in accounts payable and accrued liabilities, which included a US pension funding contribution of $203 million. Cash used by investing activities of $2.79 billion primarily was due to capital expenditures ($1.62 billion), the acquisition of the 30% minority interest in WesternGeco ($2.40 billion) and the sales of investments ($1.84 billion). Cash used in financing activities was $369 million as the payment of dividends to shareholders ($420 million) and stock repurchase plan ($949 million) were only partially offset by the proceeds from employee stock plans ($346 million).

FORWARD-LOOKING STATEMENTS

This report and other statements we make contain forward-looking statements within the meaning of the federal security laws, which include any statements that are not historical facts, such as our expectations regarding business outlook; growth for Schlumberger as a whole and for each of Oilfield Services and WesternGeco (and for specified products or geographic areas within each segment); oil and natural gas demand and production growth; operating margins; operating and capital expenditures by Schlumberger and the oil and gas industry; the Schlumberger effective tax rate; the business strategies of Schlumberger customers; stock-based compensation expense; the Schlumberger stock repurchase program; and future results of operations. These statements involve risks and uncertainties, including, but not limited to, the global economy; changes in exploration and production spending by Schlumberger 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; political and economic uncertainty and socio-political unrest; and other factors detailed in our most recent Form10-K, this Form 10-Q 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 year ended December 31, 2006. Schlumberger’s exposure to market risk has not changed materially since December 31, 2006.

Item 4.

Controls and Procedures

An evaluation was carried out under the supervision and with the participation of Schlumberger management, including the Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), of the effectiveness of the design and operation of Schlumberger’s disclosure controls and procedures, as of the end of the period covered by this quarterly report, pursuant to Rule 13a-15 of the Securities Exchange Act of 1934, as amended (the

“Exchange Act”). Based on that evaluation, the CEO and CFO have concluded that Schlumberger’s disclosure controls and procedures were effective as of September 30, 2007 to ensure that information required to be disclosed by Schlumberger in the reports that it 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 and that information required to be disclosed is accumulated and communicated to management, including the CEO and CFO, 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 ended September 30, 2007 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 to the Consolidated Financial Statements.

Item 1A.

Risk Factors

We urge you to carefully consider the risks described below and in the information contained in our Annual Report on Form 10-K for the year ended December 31, 2006, as well as other reports and materials that we file with the Securities and Exchange Commission. If any of the risks described were to occur, our business, financial condition, results of operations, cash flows or prospects could be materially adversely affected. In such case, the trading price of our common stock could decline and you could lose all or part of your investment. Additional risks and uncertainties not currently known to us or that we currently deem immaterial may also adversely affect our business and operations.

Demand for the majority of our oilfield services is substantially dependent on the level of expenditures by the oil and gas industry. A substantial or an extended decline in oil or gas prices could result in lower expenditures by the oil and gas industry and reduce our operating revenue.

Demand for the majority of our oilfield services is substantially dependent on the level of expenditures by the oil and gas industry for the exploration, development and production of crude oil and natural gas reserves, which are sensitive to oil and natural gas prices and generally dependent on the industry’s view of future oil and gas prices. Oil and gas prices have historically been volatile and are affected by numerous factors, including:

•

demand for energy, which is affected by worldwide population growth and general economic and business conditions;

•

the ability of the Organization of Petroleum Exporting Countries, or OPEC, to set and maintain production levels for oil;

•

oil and gas production by non-OPEC countries;

•

political and economic uncertainty and socio-political unrest;

•

the level of worldwide oil exploration and production activity;

•

the cost of exploring for, producing and delivering oil and gas;

•

technological advances affecting energy consumption; and

•

weather conditions.

The oil and gas industry has historically experienced periodic downturns, which have been characterized by diminished demand for our oilfield services and downward pressure on the prices we charge. A significant downturn in the oil and gas industry could result in a reduction in demand for oilfield services and could adversely impact our operating results.

A significant portion of our revenue is derived from our non-United States operations, which exposes us to risks inherent in doing business in each of the approximately 80 countries in which we operate.

Our non-United States operations accounted for approximately 75% of our consolidated revenue in the first nine months of 2007 and 73% for the same period in 2006. Operations in countries other than the United States are subject to various risks, including:

•

unsettled political and economic conditions in certain areas;

•

exposure to possible expropriation or other governmental actions;

•

social unrest, acts of terrorism, war or other armed conflict;

•

confiscatory taxation or other adverse tax policies;

•

deprivation of contract rights;

•

trade restrictions or embargoes imposed by the United States or other countries;

•

restrictions on the repatriation of income or capital;

•

exchange controls;

•

inflation; and

•

currency fluctuations and devaluations.

In addition, we are subject to risks associated with our operations in countries, including Iran, Syria, Sudan and Cuba, which are subject to trade and economic sanctions or other restrictions imposed by the United States or other governments or organizations.

The occurrence of any of the risks described above could reduce our earnings and our cash available for operations.

We are also subject to risks related to investment in our stock in connection with certain US state divestment or investment limitation legislation applicable to companies with operations in these countries, and similar actions by some private investors, which could adversely affect the market for our common stock.

Environmental compliance costs and liabilities could reduce our earnings and cash available for operations.

We are subject to increasingly stringent laws and regulations relating to importation and use of hazardous materials, radioactive materials and explosives, environmental protection, including laws and regulations governing air emissions, water discharges and waste management. We incur, and expect to continue to incur, capital and operating costs to comply with environmental laws and regulations. The technical requirements of these laws and regulations are becoming increasingly expensive, complex and stringent. These laws may provide for “strict liability” for damages to natural resources or threats to public health and safety. Strict liability can render a party liable for damage without regard to negligence or fault on the part of the party. Some environmental laws provide for joint and several strict liability for remediation of spills and releases of hazardous substances.

We use and generate hazardous substances and wastes in our operations. In addition, many of our current and former properties are or have been used for industrial purposes. Accordingly, we could become subject to potentially material liabilities relating to the investigation and cleanup of contaminated properties, and to claims alleging personal injury or property damage as the result of exposures to, or releases of, hazardous substances. In addition, stricter enforcement of existing laws and regulations, new laws and regulations, the discovery of previously unknown contamination or the imposition of new or increased requirements could require us to incur costs or become the basis of new or increased liabilities that could reduce our earnings and our cash available for operations. We believe we are currently in substantial compliance with environmental laws and regulations.

We could be subject to substantial liability claims, which would adversely affect our results and financial condition.

Certain equipment used in the delivery of oilfield services, such as directional drilling equipment, perforating systems, subsea completion equipment, radioactive materials and explosives and well completion systems, are used in hostile environments, such as exploration, development and production applications. An accident or a failure of a product can cause personal injury, loss of life, damage to property, equipment or the environment,

and suspension of operations. Our insurance may not adequately protect us against liability for some kinds of events, including events involving pollution, or against losses resulting from business interruption. Moreover, in the future we may not be able to maintain insurance at levels of risk coverage or policy limits that we deem adequate. Substantial claims made under our policies could cause our premiums to increase. Any future damages caused by our products that are not covered by insurance, or are in excess of policy limits or are subject to substantial deductibles, could reduce our earnings and our cash available for operations.

Our ability to maintain technology leadership in the form of services and products could affect any competitive advantage we hold.

If we are unable to develop and produce competitive technology or deliver it to our clients in the form of services and products in a timely and cost-competitive manner in the various markets we serve, it could materially reduce our operating revenue and net income.

Limitations on our ability to protect our intellectual property rights, including our trade secrets, could cause a loss in revenue and any competitive advantage we hold.

Some of our products or services, and the processes we use to produce or provide them, have been granted United States patent protection, have patent applications pending or are trade secrets. Our business may be adversely affected if our patents are unenforceable, the claims allowed under our patents are not sufficient to protect our technology, our patent applications are denied, or our trade secrets are not adequately protected. Our competitors may be able to develop technology independently that is similar to ours without infringing on our patents or gaining access to our trade secrets.

We may be subject to litigation if another party claims that we have infringed upon its intellectual property rights.

The tools, techniques, methodologies, programs and components we use to provide our services may infringe upon the intellectual property rights of others. Infringement claims generally result in significant legal and other costs and may distract management from running our core business. Royalty payments under licenses from third parties, if available, would increase our costs. If a license were not available we might not be able to continue providing a particular product or service, which would reduce our operating revenue. Additionally, developing non-infringing technologies would increase our costs.

Failure to obtain and retain skilled technical personnel could impede our operations.

We require highly skilled personnel to operate and provide technical services and support for our business. Competition for the personnel required for our businesses intensifies as activity increases. In periods of high utilization it may become more difficult to find and retain qualified individuals. This could increase our costs or have other adverse effects on our operations.

Severe weather conditions may affect our operations.

Our business may be materially affected by severe weather conditions in certain areas where we operate. This may entail the evacuation of personnel and stoppage of services. In addition, if particularly severe weather affects platforms or structures, this may result in a suspension of activities until the platforms or structures have been repaired. Any of these events may have a material adverse effect on our operating revenue.

Item 2.

The following table sets forth certain information with respect to the Schlumberger common stock repurchase program activity for the three months ended September 30, 2007.


	Total number of shares purchased	Average Price paid per share		Total number of shares purchased as part of publicly announced program	Maximum number of shares that may yet be purchased under the program
	(Stated in thousands except per share amounts)
July 1 through July 31, 2007	1,037.2	$	90.10	1,037.2	18,018.2

	3,131.0	$	93.62	3,131.0

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 implicating the disclosure required under this Item. The number of shares of Schlumberger common stock received from optionholders is immaterial.
