TGS and Schlumberger have teamed up for a new multiclient nodal seismic project in the U.S. Gulf of Mexico, according to a news release.

Called Amendment, the project will comprise acquisition of a 2,350-sq-km multiclient seismic survey in the Mississippi Canyon and Atwater Valley protraction areas of the GoM. In the news release, Schlumberger said the area includes open acreage, existing producing assets and new discoveries.

“E&P companies are showing increased interest in the benefits of nodal seismic data to overcome imaging challenges in this region,” TGS CEO Kristian Johansen said in the release. “In the Amendment project, TGS and Schlumberger will reimage underlying WAZ seismic data to provide modern, high-quality nodal seismic data to our clients.”

The companies plan to use Fairfield Geotechnologies 4C nodal acquisition technology to acquire the seismic data, while TGS and Schlumberger will apply their full azimuth processing expertise, the news release said.

“This unique dataset will provide a step change in illuminating complex subsurface structures and help E&P companies to maximize the value of their producing assets and rejuvenate their exploration portfolios,” said Maurice Nessim, president, WesternGeco, Schlumberger. “This highly integrated project will combine well log data, high-quality orthogonal WAZ and new nodal measurements to provide foundations for the first industry-funded regional nodal survey in the deepwater Gulf of Mexico.”

Operations are scheduled to begin in fourth-quarter 2018 with final data delivered to customers in first-quarter 2020, according to the release. The survey is supported by industry prefunding.
