CGGVeritas to conduct 2D seismic surveys

CGGVERITAS WILL ACQUIRE two 2D seismic surveys offshore Gabon. The surveys will focus on Gabon's deepwater pre-salt region and provide data to complement the 10th Gabonese Licensing Round, which will take place between June and December 2010.

The two surveys will be located in the north and south of Gabon's under-explored deepwater blocks. In the north, Zone Nord, CGGVeritas will acquire a 2,200 km grid specifically designed to highlight Tertiary and Cretaceous plays.

In the south, Zone Sud, a 7,400 km very long-offset survey will provide the imaging beneath the Aptian salt to help identify potential traps. The Zone Sud survey is part of a three-phase program designed by CGGVeritas to provide a full understanding of the region in a timely and costeffective way. First, basin-wide depth modeling will be undertaken using existing data and a CGGVeritas test line.

During the second phase a comprehensive gravity gradiometry survey will provide detail on the salt architecture. This information will be used to constrain PSDM models. The third phase is the acquisition of a targeted 2D grid. The potential for further acquisition, including 3D, will be assessed after completion of the three-phase program.
