Forward-Looking Statements This presentation contains forward-looking statements. Forward-looking statements are based on management assumptions and analyses. Actual experience may differ and such differences may be material. Backlog consists of written orders and estimates for our services which we believe to be firm. In many instances contracts are cancelable by customers so we may never realize some or all of our backlog, which may lead to lower than expected financial performance. Forward-looking statements are subject to uncertainties and risks which are disclosed in Geokinetics’ Annual Report on Form 10-K.

E&P Project Cycle Explore Develop Exploit Seismic Data Acquisition and Processing Needed at All Stages of the E&P Cycle “With 3-D seismic, we can understand the detailed geology much better than before. And that translates to opportunities to drill new wells to bolster production in mature fields.” - ExxonMobil, The Lamp (2007 – Number 4) Increase drilling success rates Reduce finding and development costs

Strong Customer Relationships (Partial Customer List)

Robust Industry Fundamentals Seismic crew activity has grown steadily in land and increased rapidly in the marine streamer market in response to commodity prices, but still lags increase in drilling rigs International plays (NOCs) are a key driver for seismic growth (Domestic has been strong for the past three years) Seismic crew count in the U.S. is still less than the lowest levels in the 1990s when oil prices were near $20 per barrel Pressure for continued growth in activity, even at lower commodity prices Oil companies reloading prospect inventories – Resource plays are big drivers – Technical advances drive activity and create barriers to entry – Recent trend for more specialized crews and equipment Fundamentals are strong, but we are continually monitoring for any trend toward overcapacity
