This agreement allows TGS to significantly expand the onshore and offshore data available in Mauritania. The new subsurface data includes ten narrow-azimuth input 3D seismic surveys, processed by ION in 2022 using pre-stack 3D depth migration, resulting in a fully integrated volume merged and migrated from 19,092 km².
In addition, there are approximately 84,000 km² of 3D surveys of offshore block assignments, offshore and onshore wells, and around 20,000 line km of onshore 2D seismic data within the Taoudeni Basin. Offshore exploration in Mauritania has focused on the Cenozoic salt-covered channels, highlighted by the discovery of the Chinguetti field in 2001. Since then, most wells have targeted this proven reservoir.
Recent exploration in deepwater and neighbouring regions has revealed significant potential in Cretaceous channel sand reservoirs and shelf clastics above the carbonate platform. Untapped potential also exists in the carbonate platform and synrift areas.
David Hajovsky, Executive Vice President, Multi-Client at TGS, said: “Mauritania offers significant hydrocarbon potential. These critical data sets will provide comprehensive subsurface information, connecting drilled prospects to underexplored regions such as deepwater. When combined with TGS’ extensive database across the MSGBC basin, this will enable comprehensive megaregional analysis, improving understanding of analogues and variations along the margin.”
