Bergen, 27 May 2026. 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
programme 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 programme of work in Nigeria and across the
region", said Shearwater CEO Irene Waage Basili.
