ASKER, Norway – TGS and partner Schlumberger have started the second phase of their ultra-long offset node project in US Gulf of Mexico.
The next phase will extend the footprint of ultra-long 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 ultra-long offsets and full waveform inversion, is expected to deliver an uplift to the velocity model which in turn will be used to amend the existing WAZ and Coil data in the area, according to TGS.
Acquisition of the project is expected to begin in April 2020 with final data available in 2021.
The Amendment and Engagement projects represent a new generation of survey design, the company said.
Kristian Johansen, CEO of TGS, said: “Green Canyon continues to experience high levels of E&P leasing activity and is a priority area for deepwater exploration activity... Once complete it will be the largest ultra-long offset node project in the world.”
This project is supported by industry funding.
