FRENCH geoscience firm CGG has announced the completion of its largest ever seafloor survey in the UK’s central North Sea.

The multi-client ocean bottom seismic (OBN) survey began in March this year.

CGG and Magseis Fairfield said approximately 1,650km of data had been gathered with first images being released in early 2021 and final PSDM data planned for release in Q4 2021.

Covering two highly prospective areas of the UK Continental Shelf, the OBN Cornerstone 2020 survey project represented a total of 813,000 man-hours with zero Lost Time Incidents (LTIs).

CGG said the work will provide a “step change” in the quality of seismic imaging and reservoir characterisation, bringing “new insight” to the development of the CNS region.

Sophie Zurquiyah, CGG chief executive officer, said: “We are pleased to announce completion of the acquisition of our OBN Cornerstone 2020 survey and would like to congratulate both the CGG and Magseis Fairfield teams for the excellent operational and HSE performance, especially within the current Covid-19 context.

“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 License Round and support the UK Oil & Gas Authority’s strategy for Maximizing Economic Recovery.”
