ASKER, NORWAY, March 9, 2020—Following the highly successful Amendment Phase 1 project acquired in Mississippi Canyon in 2019, TGS and Schlumberger today announced the second phase of their ultralong-offset node project in US Gulf of Mexico. The next phase will extend the footprint of ultralong-offset data to the Northern Green Canyon protraction area and will be called Engagement.

This area is characterized by complex geology and multiple salt bodies, driving industry toward a new approach to illuminate the subsurface structures. The combination of ocean-bottom node data, used to record ultralong offsets and full-waveform inversion (FWI), is expected to deliver a significant uplift to the velocity model, which will be used to amend the existing wide-azimuth (WAZ) and coil data in the area.

Acquisition of the project, which is supported by industry funding, is expected to commence in April 2020 with final data available in 2021. The Amendment and Engagement projects will benefit significant areas in the Gulf of Mexico and elsewhere.

Kristian Johansen, CEO at TGS, said, "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 ultralong-offset node project in the world."

Maurice Nessim, president, WesternGeco^®, Schlumberger, added, "Schlumberger and TGS continue to lead the industry in the application of next-generation seismic technology in the US Gulf of Mexico. We are very pleased to see E&P companies supporting the Engagement project, where the combination of ultralong offsets and advanced earth model building technologies will offer enhanced subsalt imaging and provide new subsurface insights into a geologically complex area."
