OSLO, Norway (06 March 2023) – TGS, a leading global energy data and intelligence provider, are proud to announce that it has secured pre-funding for a new multi-client 3D seismic survey in West Africa. This project will commence in Q2 2023 and will be the first 3D project to be performed under the recently announced multi-year vessel agreement with COSL.

This project will expand TGS’ 3D seismic data coverage, providing high-quality data in a key emerging basin in one of West Africa’s prolific hydrocarbon provinces. The survey will be conducted with long offsets. It will be processed using Pre-stack Time (PSTM) and Pre-Stack Depth (PSDM) workflow with Full Waveform Inversion (FWI), enabling improved imaging of the subsurface for acreage evaluation, supporting license rounds within the region and providing excellent growth opportunities for energy companies.

The survey will be acquired by COSL’s HAI YANG SHI YOU 721 (HYSY721) state-of-the-art vessel, scheduled to mobilize in Q2-2023, with final processed deliverables to be completed by Q3-2024.
