Exhibit 99.1

HOUSTON, TEXAS — February 15, 2010 — Geokinetics Inc. (NYSE Amex: GOK) announced today that it has completed its acquisition of Petroleum Geo-Services’ (“PGS”) onshore seismic data acquisition and multi-client data library business (“PGS Onshore”).

“The combination of PGS Onshore and Geokinetics solidifies our position as the clear leader in the onshore seismic data acquisition business,” said Richard F. Miles, President and Chief Executive Officer of Geokinetics. “It not only brings together two strong complementary seismic data acquisition operations, but it also accelerates our strategic initiatives in the multi-client library business.”

“We are pleased to welcome the management and employees of PGS Onshore to our team and look forward to providing our customers worldwide with an expanded array of best-in-class services and data,” said Miles.

The purchase price paid by Geokinetics at closing was $210 million, on a cash free, debt free basis, less a $2.8 million adjustment for estimated net working capital below the included amount of $37.5 million.  The purchase price is subject to certain additional working capital adjustments after closing.

Geokinetics has funded this acquisition through a combination of cash and common stock.  At closing, Geokinetics issued PGS approximately 2.15 million shares, which represented 19.9% of Geokinetics shares outstanding prior to the signing of the purchase agreement, valued for purposes of the transaction at $12.11 per share, or $26.1 million. This amount represents 12% of the Company’s current common shares outstanding.  The remainder of the purchase price, or $183.9 million, was paid in cash. Geokinetics used a portion of the net proceeds from a $300 million senior secured notes offering and a $37 million equity offering completed in December 2009 to finance the cash portion of the acquisition, repay current outstanding indebtedness and for general corporate purposes.

Operationally, Geokinetics’ backlog declined to $190 million as of December 31, 2009, which has and will continue to impact the Company’s operations in the near-term.  Including PGS Onshore’s backlog, the Company’s pro-forma backlog was $378 million as of December 31, 2009.

“In the prevailing climate of general economic uncertainty, our customers are being cautious and are taking longer than normal to award projects. We have numerous bids still outstanding, especially in our high value OBC market, that were bid mid to late last year. However, bid activity is increasing and we remain optimistic that as customer confidence returns, we will see significant awards in the coming months.  In January, we completed our large OBC project in Angola that we started in the fourth quarter of 2008 and are currently demobilizing that crew while awaiting follow-on work,” concluded Miles.

In addition to the above, the Company is providing a summary of changes in its common stock below.
