Re:

Withdrawal of Form S-3, File No. of the S-3 (333-173153)

Ladies and Gentlemen:

Pursuant to Rule 477 under the Securities Act of 1933, SandRidge Energy, Inc. (the “Registrant”) hereby requests the withdrawal of its registration statement on Form S-3 (the “Registration Statement”) (File No. 333-173153) filed on March 30, 2011. This application for withdrawal is being made because the registration statement was inadvertently tagged with an incorrect EDGAR submission code. The Registrant is filing the appropriate Form S-3ASR concurrently with this withdrawal request. Accordingly, we request that the Commission issue an order granting the withdrawal of the Registration Statement as soon as possible.

We appreciate your assistance and should you need any additional information, please feel free to contact me at (405) 429-6136.
