Cornerstone

UK 32nd License Round

CGG Multi-Client data library offers the most recent and most advanced seismic coverage of the Central North Sea (CNS), North Viking Graben (NVG), Southern North Sea (SNS) and West of Shetlands (WOS). OGA 32nd License Round includes a significant number of blocks on offer over CGG’s North Sea datasets.

These groundbreaking datasets, processed with the latest technologies, will assist the industry with their exploration and production challenges, designed to help develop new opportunities within the mature areas of the UK Continental Shelf.

Cornerstone Evolution is the latest iteration of central north sea reprocessing, using the latest cutting-edge imaging technology to create a seamless volume of over 50,000 km² of high-quality, long-offset data.

Cornerstone Evolution

This dataset will be available to help de-risk acreage available in the 32nd UK Offshore Licensing Round. Processing is tailored to address local geological complexities, with model-building benefiting from Q-Tomography, Q-FWI, and Q-RTM. Final PSDM data will include Least Squares Q-Kirchhoff and Wave Equation migrations.

Evolution salt model with improved flank imaging

The latest Cornerstone Evolution salt model provides improved imaging of the salt flanks.
