The Leading Edge | Zedong Wu, Zhiyuan Wei, Zhigang Zhang, Jiawei Mei, Rongxin Huang, Ping Wang ©2025 SEG | May

Full-waveform inversion (FWI) has found great success in different geologic settings and has become a must-have tool for velocity model building (VMB), particularly in salt environments where geology and velocity are often highly complex. While still acoustic, FWI has already significantly improved salt models ...

Technical Abstract
EAGE Annual - European Association of Geoscientists and Engineers | Matthew Ledger, Steve Hollingworth, Keith Maynard, Bill Leslie, Fabien Allo (Viridien) ; Alexandra Makrygiannis, John Reidar Granli, Eivind Skare, Thomas Melgaard, Damian Leslie (OMV) ©2024 EAGE | December

This case study demonstrates the collaborative advantages when an Operator and a Geoscience Contractor work collectively as part of a tailor-made Integrated Virtual Asset team, to solve complex subsurface challenges in a restricted time frame. The operating challenge was to de-risk a potential drilling ...
