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.
