TGS to start next phase of Gulf of Mexico seismic project

Norwegian seismic player TGS is preparing to start the second phase of its ultra-long offset node project in the U.S. Gulf of Mexico.

Following the highly successful Amendment Phase 1 project acquired in Mississippi Canyon in 2019, TGS and its partner Schlumberger on Monday announced the second phase of the project which would extend the footprint of ultra-long offset data to the Northern Green Canyon protraction area.

The acquisition of the industry-funded project, named Engagement, is expected to begin in April 2020 with final data available in 2021.

TGS said on Monday that the Amendment and Engagement projects represent a new generation of survey design, with benefits for significant areas in the Gulf of Mexico and elsewhere.

The combination of ocean bottom node data used to record ultra-long offsets and full-waveform inversion is expected to deliver a significant uplift to the velocity model which in turn will be used to amend the existing WAZ and Coil data in the area.

Kristian Johansen, CEO at TGS, stated: “Green Canyon continues to experience high levels of E&P leasing activity and is a priority area for deepwater exploration activity. This survey will be a critical tool to support our customers’ plans in this region. Once complete it will be the largest ultra-long offset node project in the world.”
