Filed February 11, 2009

File No. 001-04601

Dear Mr. Donahue:

As I indicated by telephone to you yesterday, Schlumberger has advised that it expects to be able to respond by April 10, 2009 to the comments of the staff of the Securities and Exchange Commission contained in the letter dated February 26, 2009 with respect to Schlumberger’s Annual Report on Form 10-K for the fiscal year ended December 31, 2008. The additional time should be sufficient to compile the information needed to respond to the comments.

If you have any questions, please call me at 713.229.4062 or Sean T. Wheeler at 713.229.1268.

Very truly yours,

/s/ Patrick Whitman
