FUSION M-WAZ REIMAGING IN CENTRAL US GULF OF MEXICO

TGS-NOPEC Geophysical Company (TGS) and Schlumberger announced a new multi- and wide-azimuth Fusion M-WAZ (multi- and wide-azimuth) multiclient reimaging program in the highly prospective Central U.S. Gulf of Mexico. Final results are expected in early 2018, ahead of a period when substantial block turnover in the area is anticipated. The new Fusion M-WAZ reimaging program comprises data covering more than 1,000 Outer Continental Shelf (OCS) blocks (~23,000 km2) from 3D WAZ programs previously acquired by TGS and Schlumberger with the WesternGeco Q-Marine* point-receiver marine seismic system between 2008 and 2012. This large reimaging program will process data from the Mississippi Canyon, Atwater Valley and Ewing Bank areas using the latest imaging technology to provide a significant uplift in data quality for upcoming licensing rounds. The area is expected to remain a high priority for E&P companies in the foreseeable future and will benefit from two licensing rounds every year for the next five years under the new BOEM 2017-2022 Five-Year Program. The custom-processing workflow for this project will include a number of newly developed imaging technologies including 3D WAZ de-ghosting; 3D surface related multiple elimination (SRME); common offset RTM gather (COR) and image-guided tomography; and orthorhombic anisotropy velocity modelling. During the reprocessing, geoscientists will update the salt interpretation and add input from the latest well data released for the area. (Source: Schlumberger)
