CGG, TGS partner for multi-client seismic survey on Norwegian Continental Shelf
(WO) — CGG and TGS have won the acquisition and imaging of a dense ocean bottom node (OBN) multi-client seismic survey in the Balder and Ringhorne areas of the Norwegian Continental Shelf (NCS).
The Heimdal Terrace OBN survey, located directly north of the Utsira OBN survey in the North Sea, will span an additional 500 km2 area under receivers (AUR) to increase the contiguous multi-client OBN coverage in the region to 3,778 km2 AUR.
The survey area covers a mature part of the North Sea, including the Balder and Ringhorne fields, the Iving/Evra and Enniberg discoveries, and surrounding infrastructure-led exploration (ILX) areas for potential tiebacks to existing infrastructure.
TGS will be the operator throughout the acquisition phase. The company will apply its experience and technical expertise in managing many complex OBN acquisition programs in the North Sea and other regions to provide valuable insight into enhanced exploration opportunities across this part of the NCS.
CGG, the OBN imaging specialist, will apply its proprietary OBN processing and imaging technology, including time-lag full-waveform inversion, to create a high-quality 3D volume that will enhance the resolution and structural definition of the complex geology and reservoirs in the region.
The acquisition will begin in April 2023, with final processed deliverables to be completed by the end of Q2 2024.
