CGG has been awarded a big project by Lundin Energy Norway for the seismic imaging of an innovative simultaneous node and streamer 3D survey currently being acquired over a 3700 km 2 area of the Nordkapp basin in the Barents Sea.
CGG has been awarded a big project by Lundin Energy Norway for the seismic imaging of an innovative simultaneous node and streamer 3D survey currently being acquired over a 3700 km2 area of the Nordkapp basin in the Barents Sea.
The survey combines TopSeis, the source-over-spread seismic technology developed by CGG in collaboration with Lundin, with the deployment of sparse ocean-bottom nodes. This configuration is designed to obtain a high-definition image of the sedimentary basins and accurately image the numerous salt flanks to improve the understanding of trap mechanisms, deformation and faulting near salt-sediment interfaces.
Using CGG’s expertise in TopSeis and OBN imaging, the data will be processed at CGG’s Massy subsurface imaging centre in France where its proprietary velocity model building and depth imaging technologies, including CGG’s time-lag full-waveform inversion and full-waveform inversion imaging, will be deployed to derive a velocity model.
Meanwhile, CGG has closed the sale of its multi-physics business, except its processing and multi-client library, to Xcalibur Group.
