Item 2.02 Results of Operations and Financial Condition.

The Third Quarter 2008 Press Release furnished as Exhibit 99.1 hereto and the Supplemental Information regarding Third Quarter Results furnished as Exhibit 99.2 hereto, were posted on the Schlumberger internet web site (www.slb.com/ir) on October 17, 2008.

In addition to financial results determined in accordance with generally accepted accounting principles (GAAP) that are included in the attached Third Quarter 2008 Press Release and Supplemental Information, these documents also include the following non-GAAP financial measure (as defined under Regulation G of the Securities Exchange Act of 1934):

• Net debt: Net debt represents gross debt less cash, short-term investments and fixed income investments, held to maturity. Management believes that net debt provides useful information regarding the level of Schlumberger's indebtedness by reflecting cash and investments that could be used to repay debt.

The foregoing non-GAAP financial measure should be considered in addition to, not as a substitute for, or superior to, total debt, cash flows or other measures of financial performance prepared in accordance with GAAP as more fully discussed in Schlumberger's financial statements and filings with the Securities and Exchange Commission.
