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 ...

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 ...

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’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 ...

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 ...

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 ...

Ultra high-resolution (UHR) marine seismic is a scaled-down version of conventional seismic acquisition. Source-receiver separation and depth, shooting rate and seismic wavelengths are typically ten times smaller than for conventional seismic operations. Under ideal conditions, ten times higher subsurface resolution may be achieved, but ...

Our Head of Geoscience explains how Viridien’s latest seismic technologies, such as full-waveform inversion and the Sercel Tuned Pulse Source (TPS), are delivering outstanding early-out results on this next-generation multi-client program.
