PARIS – CGG has started a new seismic data reimaging program in the Walker Ridge area in the Gulf of Mexico.
The Walker Ridge program covers about 300 outer continental shelf blocks. This is said to be part of a major reimaging campaign being conducted in the Gulf of Mexico.
Given recent discoveries and proven production in Walker Ridge, the new program has received strong industry prefunding from clients, the company said.
Its Walker Ridge Wide-Azimuth and StagSeis DEUX surveys will provide input for the project, and the reprocessed data will deliver high-quality imaging throughout the program with two priority discovery areas being processed on an accelerated schedule.
Final products are expected in February 2021 and May 2021, respectively. The full program results are due out by the end of 2021.
The target of the company’s new program is the prolific Wilcox formation which is deformed by thrusts and folds beneath multiple thick salt sheets and shales that have historically been difficult to image. To better define this challenging and complex area, it will reprocess existing data with 3D deghosting, 3D SRME and its advanced new velocity modeling technologies, including time-lag FWI and FWI imaging.
According to the company, preliminary test results show significant uplift in imaging of the subsalt fold-belts and continuity of reflectors within the Eocene and Paleocene exploration targets.
