Viridien, SLB Set to Launch ‘Massive’ OBN Survey Offshore Egypt
Viridien and SLB have entered into an agreement with the Egyptian Natural Gas Holding Company (EGAS) to launch a massive multi-client ocean bottom node (OBN) seismic acquisition and imaging program in Egypt’s Eastern Mediterranean offshore.The largest project of its kind in the region, it will combine the recognized OBN expertise of both parties to deliver an unparalleled subsurface dataset for Egypt and international exploration partners.This project will give explorers and investors a clearer understanding of the region’s complex subsurface and help them identify new opportunities for
Viridien Completes Reimaging of BM-S-2 Multi-Client Survey in Santos Basin
Viridien has successfully completed the BM-S-2 seismic reimaging project in the southern Santos Basin, delivering a modern, high-fidelity 3D dataset across 8,468 sq km to support growing exploration activity in one of the most strategic, emerging offshore regions of Brazil.The project upgrades a large legacy survey with the latest advanced imaging technologies, including time-lag full waveform inversion (TL-FWI), to provide clearer definition of post-salt stratigraphy, improved visibility of potential direct hydrocarbon indicators (DHIs), and new insights into underexplored pre-salt plays. The reimaged
