TGS begins 3D survey in US Gulf of Mexico

TGS has commenced Sophies Resolve Refocus 3D, an ocean bottom cable (OBC) and narrow azimuth (NAZ) imaging program in the U.S. Gulf of Mexico.

The program includes approximately 6,175 square kilometers of reprocessed 3D seismic data and presents the next phase of high-quality imaging over the mature, hydrocarbon-producing areas of South Timbalier, Grand Isle and Ewing Bank.

The aim of the project is to provide a high-quality regional product, helping E&Ps further explore new and existing plays in this area.

TGS will apply dynamic matching full waveform inversion (FWI) imaging technology to explore the key subsurface structures and provide new insight into the prospectivity within the deeper sub-salt section.

The project started in Q2 of 2021 and final data will be available in Q3 2022.

“The Gulf of Mexico remains a top priority for TGS. By utilizing the latest imaging techniques, this program provides our customers with the most comprehensive view of the subsurface so they can make the best decisions about their investments – underpinning our commitments to customer service and sustainable operations”, said Kristian Johansen, CEO at TGS.
