TGS said on Friday that the project, named “Amendment”, would comprise the acquisition of a 2,350 square kilometers of a multi-client seismic survey in the Mississippi Canyon and Atwater Valley protraction areas of the U.S. Gulf of Mexico.

This prolific area includes open acreage, existing producing assets, and new discoveries. Seismic data will be acquired using Fairfield Geotechnologies 4C nodal acquisition technology.

Operations on the project are expected to begin in the fourth quarter of 2018 while the final data would be delivered to customers in the first quarter of 2020.

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

Maurice Nessim, president of WesternGeco, Schlumberger, added: “Schlumberger and TGS have built up extensive geophysical and geological knowledge in this prolific part of the U.S. Gulf of Mexico. In line with the WesternGeco asset-light strategy, the application of nodal seismic technology and state-of-the-art imaging techniques will help to accelerate hydrocarbon discovery, development, and production for our clients.

“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.

“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.”
