Viridien commences advanced seismic imaging of Utsira North multi-client OBN survey to support exploration and development on the Norwegian Continental Shelf
Viridien (NYSE:CGG) has initiated the processing and imaging phase of its Utsira North multi-client Ocean Bottom Node (OBN) seismic survey in the Norwegian North Sea. The 513 sq km survey, located east of the Alvheim Field in the Southern Viking Graben, will be delivered for industry licensing in Q3 2026.
The project aims to enhance understanding of Norway's strategic offshore areas, utilizing cutting-edge seismic imaging workflows and proprietary time-lag full-waveform inversion (TLFWI) technology. The survey will improve resolution of complex geological intervals and help identify new exploration targets while supporting more efficient extraction of existing reserves.

Viridien has announced the commencement of the processing and imaging phase for the in the Norwegian North Sea, following the completion of acquisition this summer. Final imaging results are scheduled for delivery for industry licensing in the third quarter of 2026.
The 513 sq km Utsira North OBN survey is located to the east of the Alvheim Field in the Southern Viking Graben and will bring crucial insights into one of Norway鈥檚 most strategically important offshore areas, unlocking opportunities for near-field exploration and more efficient extraction of existing reserves in mature basins. The survey also enriches Viridien鈥檚 expanding multi-client OBN portfolio and further consolidates its strategic position in the North Sea as a leading innovative provider of on the Norwegian Continental Shelf (NCS).
Viridien鈥檚 expert imaging teams are currently applying their cutting-edge seismic imaging workflows, including the latest proprietary technology, to deliver unprecedented seismic images of this region. As a result, Utsira North OBN will enhance resolution of the region鈥檚 complex geological intervals, illuminating how deep-seated faults help dictate sediment distribution and, in turn, clarifying the presence of reservoir facies and prospective new targets.
Dechun Lin, Head of Earth Data at Viridien, said: 鈥�Viridien鈥檚 imaging and licensing of the Utsira North OBN multi-client data reaffirms our long-term commitment to the NCS and our technological leadership in the region. Once again, as a high-value data provider, we are leveraging our unmatched subsurface imaging capabilities to deliver next-generation data that will empower E&P companies to make better decisions in mature and increasingly complex environments, maximizing returns from their existing infrastructure and near-field exploration investments.鈥�
