OSLO, Norway (20 October 2026) – TGS, in partnership with the Direction Générale des Hydrocarbures (DGH) and PETROCI, today announced the commencement of the MC3D Vision PSDM reprocessing project in offshore Côte d'Ivoire.

The project will reprocess 14,691 square kilometers of GeoStreamer 3D data from multiple surveys acquired by TGS between 2014 and 2018, covering the deepwater Côte d'Ivoire and San Pedro Basins. The reprocessing addresses imaging challenges associated with complex deepwater geology, including significant velocity variations in the overburden that can obscure deeper exploration targets and compromise amplitude fidelity. By applying modern pre-processing, advanced velocity model building, including E-DMFWI, and Kirchhoff PSDM imaging, the project is expected to provide clearer definition of reservoir intervals and stratigraphic features across the offshore Côte d'Ivoire margin.

David Hajovsky, Executive Vice President of Multi-Client at TGS, commented, “This project once again showcases our commitment to data-driven exploration across Africa. Enhanced imaging will enable operators to identify and evaluate prospects with greater confidence, reduce subsurface uncertainty and mature exploration opportunities across Côte d'Ivoire.”

The Côte d'Ivoire MC3D Vision PSDM Reprocessing adds to TGS' wider ongoing MC3D Vision reprocessing project activities across West Africa. Fast-track products are expected in Q2 2027, with final products to follow in Q4 2027.
