CGG started acquiring the Davros 3-D BroadSeis and BroadSource multiclient survey in the Northern Carnarvon Basin on the northwest shelf of Western Australia, the company said in a March 2 release. Covering more than 11,000 sq km, Davros is the largest seismic survey CGG ever acquired in the Asia-Pacific region.

Viking Vision is conducting the Davros survey using CGG’s BroadSeis variable-depth streamer configuration and BroadSource synchronized broadband multi-level source. The vessel is equipped with 12 Sercel Sentinel RD 2 Hz streamers, each measuring 8250 meters. CGG will image the data using its regional expertise and technology including pre-stack depth migration.

CGG’s CEO Jean-Georges Malcor said that the combination of BroadSeis, BroadSource and CGG’s subsurface imaging technology “will significantly enhance interpretation of the area’s Triassic to Lower Cretaceous reservoir units, which exceed 10 km in thickness and are expected to host significant quantities of hydrocarbons, as has been confirmed by these previous discoveries.”
