CGGVeritas Records First Data on Shale Gas Tri-Parish 3D Multi-Client Survey in Haynesville

Houston, 7 July 2009

CGGVeritas announced today that it has begun acquiring the Tri-Parish Line 3D multi-client survey in northern Louisiana.

The 677-square mile wide-azimuth survey is the largest contiguous Haynesville shale survey to date. It is designed to supply the numerous industry players with a state-of-the-art 3D survey to help them locate the hundreds of horizontal wells that are expected to be drilled in the play.

CGGVeritas will operate two separate 7,000-channel crews to acquire the survey over the next 12 months. The configuration of the wide-azimuth survey was specifically designed to enable enhanced fracture detection and understanding, critical parameters for exploration and production.

Original participants will systematically receive 3D processed seismic volumes as each phase of the year-long survey is completed.

Colin Murdoch, Executive Vice President, North America region, CGGVeritas, said: "The U.S. Gulf Coast has been a primary focus area for CGGVeritas for over ten years. We believe this advanced Tri-Parish Line survey in the heart of the Haynesville shale play will be a key part of our data library assets for years to come."

The Haynesville shale is a gas resource play located in northeast Texas and north Louisiana. It is one of the most active horizontal drilling areas in the US.
