Advanced Seismic Imaging in the Barents Sea

Location of TopSeis survey to be acquired over the Greater Castberg area of the Barents Sea. Source: CGG Multi-Client and New Ventures. CGG, in partnership with TGS, will acquire a 5,000 km² multi-client 3D survey in the Barents Sea this summer. The survey will use the latest developments of CGG's TopSeis technology, combining an innovative source-over-spread acquisition configuration with advanced imaging to enable delineation of shallow-to-intermediate depth targets in the Barents Sea, not resolvable by conventional methods.

The next-generation TopSeis configuration deploys five sources on the source vessel, shooting over the centre of the streamer spread. An additional source on the streamer vessel provides long-offset data for Full Waveform Inversion and deep imaging. Previous TopSeis surveys in the Barents Sea delivered superior data for imaging and AVO due to the rich near-offset coverage, high trace density and low noise.

The survey will include the prospective Greater Castberg area, covering existing and newly awarded licences as well as open acreage with several play models in multiple geological layers. Fast-track PSDM data will be available in December 2019 and final data in Q4 2020.
