TGS and CGG Announce Dense OBN Survey in the Sleipner Area of the Norwegian Continental Shelf

OSLO, Norway (22 December 2022) - TGS, a global provider of energy data and intelligence, and CGG, a global technology and HPC leader, have been jointly awarded the acquisition and imaging of a dense ocean bottom node (OBN) multi-client seismic survey in the Sleipner Area of the Norwegian Continental Shelf (NCS).

The Sleipner OBN survey, located directly south of the Utsira OBN in the North Sea, will span an additional 1,201 square kilometers area under receivers (AUR) to increase the contiguous multi-client OBN coverage in the region to 3,278 square kilometers AUR. The survey area covers a mature part of the North Sea that includes the Sleipner East, Sleipner West, Gina Krog, Volve and Utgard fields, as well as surrounding infrastructure-led exploration (ILX) areas for potential tiebacks to existing infrastructure. Current production hubs in the area enable quick transport of produced hydrocarbons, including significant volumes of gas, to the European market.
 
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. 

Kristian Johansen, Chief Executive Officer at TGS, commented, "TGS remains committed to providing the industry with world-class multi-client OBN surveys.  We are leading the way in supporting E&P companies as they seek to maximize resources in regions with strong ILX activity, including those with gas-derived exploration opportunities."

Sophie Zurquiyah, Chief Executive Officer at CGG, said, “CGG has an unrivaled track record of successfully conducting OBN seismic imaging projects around the world and in the North Sea in particular. Our geoscientists will apply their regional insight and our very latest OBN technologies and expertise to deliver the highest-quality images to meet industry needs for the continued exploration and development of the NCS.”

The acquisition will commence in June 2023, with final processed deliverables to be completed by the end of Q3 2024.

The project is supported by industry funding.
