(WO) — CGG today announces an agreement with Carbon Transition (under its subsidiary Axxis Multi Client) to reprocess the Utsira ocean bottom node (OBN) seismic survey in the Norwegian North Sea.

The reprocessing project has significant industry support and leverages strong demand for high-definition seismic imaging in this highly prospective area.

CGG will reprocess the Utsira survey, which is the largest ultra-high resolution OBN survey conducted in the North Sea and covers approximately 2,000 square kilometers. The reprocessing will apply CGG’s latest advances in OBN processing and imaging technology, including time-lag full-waveform inversion.

This will significantly improve the velocity model, overall image resolution and frequency content for fault interpretation and reservoir characterization workflows. The reprocessed product will substantially advance the Utsira OBN survey and better assist clients with existing petroleum production and reservoir management.

Dechun Lin, EVP, Earth Data, CGG, said, “The agreement recognizes CGG’s ability to provide superior OBN imaging results. This was recently demonstrated by the significant uplift in quality that we achieved on a proprietary reprocessing of a sub-set of the Utsira Survey. The result was so well received that the clients decided to commit to reprocessing the complete survey. “

Nils Haugestad, interim CEO of Carbon Transition, said, “We are confident that this new product will maximize our clients’ prospects for making new discoveries as well as optimizing existing production.”

The Utsira area holds several significant oil and gas fields, including Edvard Grieg, Ivar Aasen, Balder, Gina Krog, Gudrun and Johan Sverdrup, along with several undeveloped discoveries and prospects.

Scheduled to start in November 2022, the project will deliver a priority area in the third quarter of 2023 and final data for the complete survey in 2024.
