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.

A comprehensive seismic reservoir characterization study was conducted in a gas field in Argentina, utilizing geostatistical AVA seismic inversion to generate inputs for reliable static models and dynamic simulation. The study encompassed a range of disciplines, including petrophysics, rock physics modelling and geostatistical AVA ...

This case study demonstrates how a long-offset, wide-azimuth four-component OBN survey, in combination with Full-Waveform Inversion, can be used to produce detailed 3D images and a geobody of the Sleipner CO2 plume that can be used for quantitative analysis.

As demonstrated by recent exploration success, Viridien’s Northern Viking Graben (NVG) seismic survey in the Northern North Sea has already proven to be a valuable exploration tool. Thanks to the high-quality seismic data in this geologically challenging area, prospects are better defined, allowing for ...

Surface-related multiple elimination (SRME) is an effective and widely used tool for the attenuation of multiple energy in marine seismic data. However, removing multiples with SRME is still challenging in geologically complex areas, and we often observe residual multiples in such settings. Residual multiples ...

Viridien drills down into the prospectivity of Côte d’Ivoire’s Tano Basin while sharing the final data from its multi-client CDI23, 3D PSDM re-imaging project.

Erling Frantzen, Anna Lougon & Joe Zhou from our Earth Data team discuss how advanced geoscience technologies and data are successfully supporting energy companies in the search for hidden opportunities in the world’s hotspots.
