CGG has announced the start of a new Foz do Amazonas 3D seismic reimaging project, aimed at supporting Brazil’s Permanent Offer initiative in the Equatorial Margin.
The project, supported by industry funding, is expected to complete by the end of 2023, with fast-track products available by June.
The reimaging project will merge over 7700 km2 of existing public 3D seismic data in the Foz do Amazonas basin. The area has a rich network of turbiditic fans and channels made attractive by its geologic proximity to Guyana and Suriname and the recent success stories along the South Atlantic conjugate margins of West Africa.
Dechun Lin, EVP, Earth Data, said: “The Foz do Amazonas 3D reimaging project will benefit from our in-depth knowledge of the Equatorial Margin and further expand our 3D data library offshore Brazil, which is already the most comprehensive in the industry. By applying our unmatched imaging technology, such as our exclusive time-lag FWI, our experts in our Rio Subsurface Imaging center will deliver ultramodern high-resolution images for a better understanding of the untapped potential of the vastly underexplored Equatorial Margin.”
CGG and TGS Announce Sleipner OBN Multi-Client Survey on the Norwegian Continental Shelf
CGG, a global technology and HPC leader, and TGS, a global provider of energy data and intelligence, 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 kilometer 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 resolution and structural definition of the complex geology and reservoirs in the region.
Sophie Zurquiyah, CGG CEO, said: “CGG has an unrivalled track record of successfully conducting OBN seismic imaging projects around the world and in the North Sea in particular. Our geoscientists will apply this regional insight and our very latest OBN technologies and expertise to deliver the highest-quality OBN images to meet industry needs for the continued exploration and development of the NCS.”
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.”
The acquisition will commence in June 2023, with final processed deliverables due to be completed by the end of Q3, 2024.
