TGS and CGG have been contracted to jointly complete the acquisition and imaging of a multi-client seismic survey of dense ocean floor nodes (OBN) 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 cover an additional 193 square miles of area under receivers (AUR) to increase contiguous multi-client OBN coverage in the region to 1,459 square miles GOLD. The study area covers a mature part of the North Sea, including the Balder and Ringhorne fields, the Iving/Evra and Enniberg discoveries and the surrounding infrastructure-led exploration (ILX) areas for potential links with the existing infrastructure.
TGS will be the operator throughout the acquisition phase, while CGG will apply its proprietary OBN imaging and processing technology, including time-delayed full-waveform inversion, to create a high-quality 3D volume that improves the resolution and structural definition of the complex. geology and reservoirs of the region.
“With this latest OBN survey, we continue our ongoing commitment to support our customers with the data they need to maximize the longevity of their production activities and discover new hydrocarbon reserves in mature areas. This project acquisition will further consolidate our leadership position in providing high-quality, multi-client OBN data to the industry,” commented Kristian Johansen, CEO of TGS.
“CGG is delighted to partner with TGS to deliver this new OBN survey to meet strong industry demand for high-definition seismic data in this region. Customers continue to recognize the value of our advanced technology and expertise in ‘OBN image and the resulting data will support continued exploration and development in this mature and highly prolific part of the NCS,” said Sophie Zurquiyah, CEO of CGG.
Procurement, under the industry-funded project, will begin in April 2023, with final processed deliveries to be completed by the end of the second quarter of 2024.
