OSLO, Norway  TGS has completed its 2022 NOAKA Ocean Bottom Node (OBN) seismic survey in the Norwegian North Sea, a fortnight ahead of schedule.

This was the company’s second successive season of dense OBN data acquisition in the NOAKA region and its fourth season of multiclient OBN projects in the North Sea following NOAKA21 and the Utsira OBN project, acquired with AGS.

NOAKA22 extended OBN coverage in the region by 318 sq km (area under receiver) and lifted TGS’ OBN compilation, which included completing the remainder of the NOAKA21 survey, to 475 sq km.

Aker BP and its partners plan to develop more than 500 MMboe from the NOAKA fields, with further prospectivity anticipated, TGS said, supported by results from high-resolution OBN seismic imaging.

The company will employ full azimuth and ultra-long offsets to understand and clarify the complex geology, along with multicomponent processing to achieve stable low frequencies, high signal-to-noise ratios, reliable AVO, and the ability to distinguish between structure and attribute anomalies for field development and near-field exploration.

Final processing deliverables should follow late next year.
