Repurposing seismic data for carbon storage activities
Repurposing seismic data for carbon storage activities
Carbon storage licensing on the Norwegian Continental Shelf has gained momentum, highlighting its role in the energy transition. Legacy seismic data, originally acquired for oil and gas exploration, is a valuable asset for assessing carbon storage reservoir potential. Maximising the value of this data ...
Benchmarking Inversion Methods Over the Agat Play Using Reimaged Data Over the Måløy Slope
Benchmarking Inversion Methods Over the Agat Play Using Reimaged Data Over the Måløy Slope
Viridien has conducted a test of inversion techniques to evaluate which methods prove useful over large areas of interest. Both Extended Elastic Impedance coloured inversion (EEI-CI) and Deterministic Elastic Inversion (DEI) were evaluated as exploration screening tools for the Lower Cretaceous Agat play on ...
Advancing subsalt imaging in the US Gulf: Operational and technical innovations in seismic data acquisition from the Laconia sparse OBN program
Advancing subsalt imaging in the US Gulf: Operational and technical innovations in seismic data acquisition from the Laconia sparse OBN program
The Laconia program marks a major advancement in the design and execution of long-offset, low-frequency (LOLF) ocean-bottom node (OBN) seismic acquisition programs for subsalt imaging in the U.S. Gulf. With more than 18,000 km²of source coverage and more than 8000 node locations, this multiphase ...
Cameroon: Unlocking potential and reigniting exploration
Cameroon: Unlocking potential and reigniting exploration
Cameroon’s Douala/Kribi-Campo (DKC) and Rio del Rey (RDR) basins offer significant exploration opportunities, underpinned by advanced seismic reimaging, integrated geological evaluation and modern interpretation techniques. In the RDR Basin, focus is shifting from the mature shallow Miocene-Pliocene plays to deeper Cenozoic turbidites and the ...
Full Waveform Inversion (FWI) has become a standard method for generating high-resolution subsurface velocity models. Advances in FWI now allow the use of the full recorded wavefield, including diving waves, primary reflections, and multiples, leading to improved velocity updates even below the maximum penetration ...
A New Vision of Oil and Gas Prospectivity in the Northern Caspian Shelf
A New Vision of Oil and Gas Prospectivity in the Northern Caspian Shelf
Renewed exploration success in the Kazakhstan Sector of the Caspian Sea (KSCS) depends on a critical reassessment of existing results and a redefined understanding of the region’s hydrocarbon potential. This study presents one such reassessment, integrating geological and geophysical data with newly reprocessed seismic ...
Mozambique's Deepwater Zambezi Basin: Where AVO meets untapped opportunity
Mozambique's Deepwater Zambezi Basin: Where AVO meets untapped opportunity
As global energy demand continues to rise, continued investment in oil and gas will be critical to keep pace. Recent frontier basin exploration, particularly in deepwater basins in Namibia, Côte d’Ivoire, Guyana and Brazil, have yielded high-impact discoveries. However, these settings demand identification of ...
