TGS and WesternGeco have announced an extension of their ultra-long offset ocean-bottom node (OBN) acquisition in Green Canyon, US Gulf of Mexico.
The 168 OCS block survey began in August 2021 and is now expected to be completed during the first quarter of 2022. Key to this project is the use of data for full-waveform inversion (FWI) velocity model building. The results from data processing are expected in mid- 2022. This project extends the engagement phase 1 survey acquired to the north in 2020.
Kristian Johansen, CEO at TGS, said: ‘Starting with Amendment Phase 1 in 2019, TGS and WesternGeco have been at the forefront of improved imaging in ultra-long offset OBN acquisition in a highly prospective area of the US Gulf of Mexico.’
