TGS has announced the Declaration Refocus next generation M-WAZ imaging program in Mississippi Canyon in the US Gulf of Mexico. The new, high-end re-imaging workflow is designed to provide enhanced imaging and greater illumination of prospectivity in the area. The program comprises data covering more than 380 Outer Continental Shelf (OCS) blocks (~8,860 km2) from orthogonal 3D WAZ programs previously acquired by TGS using WesternGeco Q-Marine and CGG StagSeis seismic systems between 2010 and 2015. Full product delivery of Declaration Refocus is expected at the end of 2020, which will solidify TGS’ core position in the US GoM.

Kristian Johansen, CEO of TGS, says, “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. Combined with our vast library of well information and our trusted imaging solutions, we continue to provide customers with the most comprehensive range of subsurface data in the Gulf of Mexico.”

The new imaging project will process data from the prolific Mississippi Canyon, Viosca Knoll and De Soto Canyon areas using the latest imaging technologies to provide a significant uplift in data quality. 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. The Declaration area is one of the most active for E&P companies in the US GoM and will benefit from two licensing rounds every year under the BOEM 2017-2022 Five-Year Program.

The project is supported by industry funding.
