Northwest Africa
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.
