CGG Completes Phase 1 of Davros 3D Multi-Client Seismic Survey in NWS



CGG reported Thursday that the final pre-stack depth-migrated data for Phase 1 of its Davros 3D BroadSeis and BroadSource multi-client survey in the Northern Carnarvon Basin on Australia's North West Shelf has been completed.

The Davros survey, covering 2,471 square miles (6,400 square kilometers) and the largest multi-client seismic program ever to be acquired and processed by CGG in Asia Pacific, has been processed by CGG's Perth and Melbourne centers, using its latest high-end subsurface imaging technology including pre-stack depth migration (PSDM) and advanced demultiple algorithms to provide the highest-resolution images.

CGG is currently processing Phase 2 of the survey, with completion expected in the fourth quarter of 2016.

"The new broadband data from our Davros survey is delivering deeper and clearer images than previously seen in this area. As a result of the exceptional penetration power of the BroadSeis low frequencies, at least 12.4 miles (20 kilometers) of sediment is visible. When combined with our advanced imaging technologies, this new data shows exceptional clarity of the deep geological structure and dramatically enhances understanding of this prospective area," Sophie Zurquiyah, chief operating officer, Geology, Geophysics & Reservoir, at CGG said in the press release.
