CGG and Magseis Fairfield have completed acquisition of the largest OBN survey ever acquired in the North Sea.
CGG and Magseis Fairfield have completed acquisition of the largest OBN survey ever acquired in the North Sea.
Approx. 1650 km2 of long-offset, full-azimuth data have been acquired, with first images being made available in early 2021 and final PSDM data planned for release in Q4 2021. Further extensions of the OBN Cornerstone survey are being considered for 2021.
Covering two highly prospective areas of the UK Continental Shelf, the OBN Cornerstone 2020 survey is designed to address the challenges associated with deeper, higher-risk Jurassic and Triassic plays, typically under high-pressure, high-temperature conditions, and the presence of complex structural processes associated with Permian salt movement. The combination of full-azimuth imaging, additional fold and near-offset data will result in significant improvement of deep illumination and noise removal, while helping to illuminate and image the steep flanks and complex architecture created by salt diapirism.
The OBN Cornerstone 2020 multi-client survey in the UK Central North Sea commenced in March 2020 and has already received significant industry interest and prefunding, said CGG.
Sophie Zurquiyah, CEO, CGG, said: ‘The new high-technology data set will complement CGG’s extensive high-quality Cornerstone towed-streamer data library, providing our clients with the best available information to de-risk the awarded blocks from the UK 32nd Licensing Round and support the UK Oil & Gas Authority’s strategy for maximizing economic recovery.’
