    ASKER, Norway -- TGS-NOPEC Geophysical Co. (TGS) and WesternGeco have agreed to acquire a second multi-client WAZ 3D survey in the Green Canyon and Atwater Valley areas of the Gulf of Mexico.

    The Liberty WAZ multi-client 3D project covers approximately 3,000 sq km (1,158 sq mi) and is adjacent to the 15,000-sq-km (5,792-sq-mi) Freedom WAZ 3D project. Both surveys use WesternGeco Q-Technology and offer onboard Wave Equation Migration in order to provide a quick-look data volume to participating clients. The final data volumes will offer Wide Azimuth 3D data coverage over more than 18,000 sq km (6,950 sq mi), the companies say.

    Acquisition of the data, using a 2x4 configuration (two streamer vessels with source and two source vessels), will begin in the third quarter. TGS and WesternGeco will collaborate on the data processing and provide a wide range of final depth imaged products to clients.
