Shearwater Geoservices AS (Shearwater) has successfully completed a 3D marine seismic survey on behalf of TotalEnergies EP Nigeria Limited and Matrix Energy on blocks OML 100 and OPL 2010, offshore Nigeria, which was executed in partnership with Harvex Geosolutions.

The two-month survey acquired high-quality 3D data using a towed-streamer configuration with an undershoot. The SW Duchess served as the primary seismic vessel, with the SW Gallien acting as the dedicated source vessel. The program builds on Shearwater’s growing footprint in Nigeria and follows an expanding sequence of work in the wider West African region.

“Shearwater is pleased to complete this 3D towed‑streamer and undershoot survey offshore Nigeria, which continues our strong relationship with TotalEnergies and builds on a program of work in Nigeria and across the region”, said Shearwater CEO Irene Waage Basili.
