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 ...

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 ...
Ultra high-resolution shallow marine imaging with a sparker over a deep streamer
Ultra high-resolution shallow marine imaging with a sparker over a deep streamer
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 ...

Geostatistical AVA seismic inversion for reservoir characterisation of the Pozo D-129 formation: A case study in San Jorge Basin, Argentina
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 ...
A breakthrough in the imaging of a CO2 plume - using OBN data to the full
A breakthrough in the imaging of a CO2 plume - using OBN data to the full
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 ...
