Declaration Refocus

Next Generation M-WAZ Imaging Program in the U.S. GOM

Declaration Refocus

The Declaration Refocus Program is the next generation M-WAZ imaging program in Mississippi Canyon in the U.S. Gulf of Mexico. The new, high-end re-imaging workflow is designed to provide enhanced imaging and greater illumination of prospectivity in the area. TGS is applying a combination of technologies including Dynamic Matching FWI to improve the velocity and salt model, and increase the frequency content in data. This reprocessing has strong support from many exploration and production companies and is targeting the Mesozoic level, including the highly prolific Norphlet play, as well as shallower horizons. The program comprises data covering more than 380 Outer Continental Shelf (OCS) blocks (~8,860 square kilometers) from orthogonal 3D WAZ programs acquired by TGS, between 2010 and 2015, using WesternGeco Q-Marine and CGG StagSeis seismic systems.  Full product delivery of Declaration Refocus is expected at the end of 2020, which will solidify TGS’ core position in the U.S. Gulf of Mexico.
