Schlumberger, TGS Bags New US Seismic Project

Norwegian seismic specialist TGS-NOPEC Geophysical Company (TGS) and oilfield services providers Schlumberger have announced a new multiclient nodal seismic project in the U.S. Gulf of Mexico.

The project, named Amendment, will comprise acquisition of a 2,350-km2 multiclient 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 with operations expected to commence in Q4 2018. TGS and Schlumberger will apply their full azimuth processing expertise and expect to deliver final data to customers in Q1 2020.

"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," said Kristian Johansen, CEO of TGS.

Maurice Nessim, president, WesternGeco, Schlumberger, said, "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."

Nessim added, "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."

This survey is supported by industry prefunding. TGS provides multi-client geoscience data to oil and gas Exploration and Production companies worldwide. Schlumberger is the world's leading provider of technology for reservoir characterization, drilling, production, and processing to the oil and gas industry.
