Greater Castberg, Barents Sea

CGG intends to acquire a 5,000 sq km multi-client 3D survey with TGS in the Barents Sea in the summer of 2019. This survey will be acquired and processed using the latest developments of CGG's TopSeis acquisition and imaging technology. The unique TopSeis solution combines an innovative source-over-spread configuration with CGG's advanced imaging technology, to deliver vastly increased near offset coverage. This enables our clients to delineate shallow-to-intermediate depth targets in the Barents Sea, which are not resolved by conventional methods.

The survey will include the highly prospective Castberg area, and cover existing and newly awarded licenses in addition to open acreage with several play models in multiple geological layers. The acquisition is expected to commence late Q2 2019 with final seismic data delivery to clients in Q4 2020.

The survey will incorporate:

• Next-generation TopSeis configuration:
• Five sources deployed on source vessel
• Additional source on streamer vessel to provide long-offset data for FWI and deep imaging
• Superior imaging and AVO quality:
• Rich near offsets
• High trace density
• Low noise



Fast-track PSDM data will be available in December 2019.
