Re:	Geokinetics Inc. 2007 Stock Awards Plan
	Registration Statement on Form S-8

Ladies and Gentlemen:

We have acted as legal counsel to Geokinetics Inc., a Delaware corporation (“Geokinetics”), in connection with the registration with the Securities and Exchange Commission on Form S-8 of certain shares of Geokinetics Inc. Common Stock, $.01 par value (the “Shares”), which will be issuable upon exercise of awards granted under the above-referenced plan (the “Plan”).  You have requested that we furnish to you our legal opinion with respect to the legality of such Shares.

In connection with the above registration, we have reviewed the proceedings of the Board of Directors of Geokinetics relating to the registration and proposed issuance of the Shares, the Certificate of Incorporation of Geokinetics and all amendments thereto, the Bylaws of Geokinetics and all amendments thereto, and such other documents and matters as we have deemed necessary in rendering the opinion contained herein.  We have assumed the authenticity and completeness of all records, certificates and other instruments submitted to us as originals, the conformity to original documents of all records, certificates and other instruments submitted to us as copies and the correctness of all statements of fact contained in all records, certificates and other instruments that we have examined.

Based upon that review, it is our opinion that the Shares, when issued in conformance with the terms and conditions of the Plan, will be legally issued, fully paid, and nonassessable under the Delaware General Corporation Law.

We consent to the use of this opinion as an exhibit to the Registration Statement on Form S-8 filed with the Securities and Exchange Commission in connection with the registration of the Shares.

Very truly yours,

/s/ CHAMBERLAIN, HRDLICKA, WHITE,
