TGS said on Monday that the new re-imaging workflow, named Declaration Refocus, was designed to provide enhanced imaging and greater illumination of prospectivity in the area.

According to the company, the program comprises data covering more than 380 Outer Continental Shelf or around 8,860 square kilometers from orthogonal 3D WAZ programs previously acquired by TGS using WesternGeco’s Q-Marine and CGG’s StagSeis seismic systems between 2010 and 2015.

TGS added that the full product delivery of Declaration Refocus was expected at the end of 2020. The new imaging project will process data from the prolific Mississippi Canyon, Viosca Knoll, and De Soto Canyon areas.

Particular attention will be given to increasing frequency content and resolution throughout the entire data section with additional focus on the Norphlet formations. The imaging process will also provide enhanced velocity and salt models.

Kristian Johansen, CEO of TGS, said: “We are extremely pleased to begin the next phase of imaging over the data-rich Declaration survey. By applying our most advanced imaging techniques to this highly-successful region, TGS will further illuminate key subsurface structures and continue to provide the industry with unprecedented insight and continuous coverage across this prolific basin.”

The Declaration area is one of the most active for E&P companies in the U.S. Gulf of Mexico and will benefit from two licensing rounds every year under the BOEM 2017-2022 Five-Year Program.
