CGG begins Gulf of Mexico seismic shoot

French geophysical services company CGG has started the acquisition of its first complementary wide-azimuth (CWAz) survey in the southern Alaminos Canyon, Gulf of Mexico.

CGG said on Monday that the BroadSeis 3D multi-client program, known as AC CWAz, of the Alaminos Canyon extended over 130 OCS blocks and covering Great White and the recent Whale discovery.

The AC CWAz is supported by industry funding and complements CGG’s existing surveys in the area by adding azimuth and offset coverage to the historic wide-azimuth data.

All the data will be combined and reprocessed using the latest 3D deghosting, full-waveform inversion (FWI), especially reflection-based FWI (RFWI), and tilted transverse isotropy (TTI) imaging technology. Fast-Trax PSDM products will be available shortly after the completion of the acquisition.

Jean-Georges Malcor, CEO of CGG, said: “Our AC CWAz multi-client survey builds on the success of the Encontrado survey by extending our high-quality images across the US portion of the Perdido Fold belt.

“This new program will provide the best images available of the complex geology and reservoirs of this highly prospective area. It also reflects CGG’s commitment to innovate and invest in solutions that enable our clients to optimize their development plans and evaluate the exploration potential in this proven region.”
