Cornerstone

UK 32nd Licensing 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.

If you are looking for coverage outside of our core Cornerstone area, or in the wider UKCS, our TerraCube™ suite of interpretative products based on legacy well and reprocessed seismic data provides regional context.
