Norway's TGS-NOPEC Geophysical Company (TGS) and Schlumberger have signed a new multi-and wide-azimuth (M-WAZ) multiclient reimaging programme in the 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 programme comprises data covering more than 1,000 Outer Continental Shelf (OCS) blocks 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 reimaging programme 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.
“This highly prospective region is a core area for TGS and Schlumberger, where we have a close relationship with customers who continue to demand the best data to support their exploration and drilling activities,” said Kristian Johansen, CEO, TGS.
Maurice Nessim, president, WesternGeco, Schlumberger, added, “This reimaging collaboration combines the use of the latest reimaging technology with high quality Q-Marine measurements and extensive geophysical and geological knowledge of this prolific area. Customers have shown great interest and we are confident that this project will afford them a competitive advantage in the upcoming lease rounds and ahead of the large block turnover.”
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.
