Nigeria License Round

Regional Highlight:
Nigeria Mini Bid Round

A mini bid round has been announced by the Federal Government of Nigeria. Seven deep offshore oil and gas blocks are on offer, with the round providing interested parties the chance to invest in the region's potential for oil and gas. TGS-PetroData offers data to de-risk exploration plays in the deep-water region.

Northwest Africa

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 offers 2D and 3D seismic in continuous coverage from MSGBC to Liberia, with supporting MBSS geochemistry, and continues to prove a working hydrocarbon system here.

West Africa Transform

West African Transform

The West African Transform Margin (WATM) stretches from Sierra Leone in the west to Benin in the east.

What was once frontier territory for oil and gas exploration has had some of the most exciting discoveries in recent years.

Southwest Africa

Southwest Africa

TGS holds the largest and most extensive 2D library in Namibia and South Africa with over 97,500 km and is adding to it by tieing recent discoveries to explore analogous plays.


Explore Region

East Africa

East Africa

East Africa contains several offshore basins, some of which are still unexplored for oil and gas.

TGS offers comprehensive seismic coverage of the region, combined with well data, gravity and magnetic surveys, and other geoscience data.
