The principal executive offices of Geokinetics are located at One Riverway, Suite 2100 Houston, Texas 77056. The following amendments to the Schedule 13D are hereby made.

Item 4. Purpose of Transaction – Restructuring of Company

On January 15, 2013, Geokinetics Inc. (the “Company”), Geokinetics Holdings USA, Inc., a wholly owned subsidiary of the Company (“Holdings”), and the Company’s other direct and indirect domestic subsidiaries (together with Holdings, the “Subsidiaries”) entered into a Restructuring Support Agreement (the “Agreement”) with holders of more than 70% in aggregate principal amount of Holdings’ 9.75% Senior Secured Notes due 2014 (the “Notes”) and Avista and Avista Offshore, the largest holders of the Company’s outstanding Series B-1 Senior Convertible Preferred Stock, Series C-1 Senior Preferred Stock and Series D Junior Preferred Stock (collectively, the “Preferred Stock”). Under the terms of the Agreement, the Company and the Subsidiaries agreed to implement a financial restructuring of the Company and the other parties to the Agreement agreed to support and vote for either a pre-negotiated or pre-packaged plan of reorganization, in each case in accordance with the terms, and subject to the conditions, set forth in the Agreement. Under the proposed plan of reorganization, the Company will (i) exchange the Notes for 100% of the issued common stock of the reorganized Company, subject to dilution from a management incentive plan to be adopted by the reorganized Company and the conversion of up to $25 million of debtor in possession financing into common stock of the reorganized Company, (ii) repay $50 million in loans plus accrued interest outstanding under Holdings’ revolving credit facility from the proceeds of an exit financing facility to be entered into in connection with the consummation of the plan of reorganization, (iii) pay general unsecured claims in full either at the conclusion of the chapter 11 case or in the ordinary course of business and (iv) make a cash payment to the holders of certain of the Preferred Stock and cancel all of the Preferred Stock. The existing holders of the common stock of the Company will not receive any distributions and their equity interests will be canceled.

The Company has publicly stated that it intends to file voluntary petitions for relief under chapter 11 of the U.S. Code in the Bankruptcy Court to implement the proposed plan of reorganization. The Company also has publicly stated that it intends to use the chapter 11 process to facilitate a financial restructuring designed to restore the Company to long-term financial health while continuing to operate in the normal course of business without interruption.

The parties’ commitment under the Agreement and the completion of the transactions contemplated by the Agreement are subject to a number of closing conditions, termination rights and approvals, including the majority of the holders of the Notes reaching an agreement with respect to various corporate governance arrangements, the approval of the Bankruptcy Court, and the finalization of definitive documentation.
