CGG has announced the start of acquisition of its first Complementary Wide-Azimuth (CWAz) survey, known as AC CWAz, a BroadSeis™ 3D multi-client program in southern Alaminos Canyon, Gulf of Mexico.

Extending over 130 OCS Blocks and covering Great White and the recent Whale discovery, 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 acquisition.

Jean-Georges Malcor, CEO, CGG, says, “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 optimise their development plans and evaluate the exploration potential in this proven region.”
