Northwest Africa has been the shining light of African exploration. That light was cast upon the region through world-class discoveries in Senegal and Mauritania. TGS 2D and 3D seismic in continuous coverage from MSGBC to Liberia, with supporting MBSS geochemistry, continues to prove a working hydrocarbon system here.

Jaan 3D (Offshore Northwest Africa)

The Jaan 3D project brings together a number of multi-client 3D seismic datasets, enhanced through reprocessing and connected with modern triple-source broadband acquisition in between. The final depth migrated volume covers over 28,300 km2 of full pre-stack merged continuous 3D, spanning the MSGBC basin.
