TGS has started the Atlantic Margin 20 (AM20) 3D multi-client seismic survey offshore north-west Europe.
TGS has started the Atlantic Margin 20 (AM20) 3D multi-client seismic survey offshore north-west Europe.
The AM20 survey covers the latest APA19 awards in the Norwegian Sea and extends west into open acreage where TGS has identified several interesting leads. This data will provide E&P companies with an interest in the continuing awards rounds with a greater geological insight, said TGS.
As an extension of the Atlantic Margin seismic programmes acquired between 2017 and 2019, the AM20 5600 km2 survey will be undertaken over a three-month period during the milder summer season and will be acquired by the Polarcus Adira. The vessel has an acquisition specification of 12 streamers and five sources, fully optimized for high lateral resolution recording, and with two 11-km streamers for full waveform inversion (FWI). TGS expects fast-track data to be available in Q4 2020, with final PSTM product delivery by Q3 2021 and final PSDM product delivery in April 2022.
Cristian Johansen, CEO at TGS, said: ‘The challenging market caused by a combination of Covid-19 and temporary over-supply of oil, points client interest to areas with regular licensing rounds, proven petroleum systems and existing infrastructure. With access to our latest AM20 data, companies will be able to confidently make their exploration decisions relating to the 2020 Norwegian Awards in Pre-defined Areas.’
Meanwhile, TGS has completed an additional phase of the Santos Basin 3D multi-client seismic survey in Brazil. The survey is located south of the high-profile discoveries in the Santos Basin and the recent sought-after blocks offered in Rounds 15 and 16. The acquisition of 17,500 km2 of the 23,000 km2 project is complete.
This multi-client 3D survey is just the latest of several 3D and 2D surveys completed in Brazil. TGS currently holds more than 452,000 km in 2D multi-client data and ~72,500 km2 in 3D multi-client data in Brazil.
Johansen said: ‘The Santos Basin is one of the most prolific exploration basins in the world with a high potential for further discoveries in deepwater. TGS will continue to prioritize Brazil.’
Full volume fast track data will be available in August 2020 with final data expected in Q2 2021.
