Re: SandRidge Energy, Inc.

Ladies and Gentlemen:

We have acted as counsel to SandRidge Energy, Inc., a Delaware corporation (the “Company”), in connection with the registration by SandRidge Mississippian Trust I, a Delaware statutory trust (the “Trust”), under the Securities Act of 1933 (the “Act”), of common units representing beneficial interests in the Trust (the “Common Units”), pursuant to the registration statement of the Trust and the Company on Form S-3 to be filed on or about October 23, 2012 (the “Registration Statement”).

We have reviewed such corporate records, certificates and other documents, and such questions of law, as we have considered necessary or appropriate for the purposes of this opinion, including the Trust Agreement of the Trust, dated December 30, 2010, by and among the Company, The Bank of New York Mellon Trust Company, N.A., as trustee (the “Trustee”), and The Corporation Trust Company, as Delaware trustee (the “Delaware Trustee”) (the “Initial Trust Agreement”), and the Amended and Restated Trust Agreement of the Trust, dated April 12, 2011, by and among the Company, the Trustee and the Delaware Trustee (the “Amended and Restated Trust Agreement” and, together with the Initial Trust Agreement, the “Trust Documents”). We have assumed that all signatures are genuine, that all documents submitted to us as originals are authentic and that all copies of documents submitted to us conform to the originals. We have assumed further that the Trust has duly authorized the Common Units. We have assumed further that the Trust is a statutory trust duly organized, validly existing and in good standing under the laws of the State of Delaware and has all requisite power, authority and legal right to issue the Common Units under the Amended and Restated Trust Agreement.

We have relied as to certain matters on information obtained from public officials, officers of the Company, and other sources believed by us to be responsible.

Based upon the foregoing, we are of the opinion that:

1. The Company is a corporation duly incorporated, validly existing and in good standing under the laws of the State of Delaware and has the corporate power and authority to execute and deliver the Trust Documents and to perform its obligations thereunder.

2. The Company has duly authorized, executed and delivered the Trust Documents.

We are members of the bar of District of Columbia and the State of New York. We do not express any opinion herein on any laws other than the law of the State of New York, the Delaware General Corporation Law, and applicable provisions of the Delaware Constitution and reported judicial decisions interpreting these laws.

We hereby consent to the filing of this opinion as Exhibit 5.2 to the Registration Statement. We also hereby consent to the reference to our firm under the heading “Legal Matters” in the prospectus constituting part of the Registration Statement. In giving such consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Act.

	Very truly yours,
