West Africa Transform Margin
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.
The WATM spans multiple countries along the West African coastline, each offering its own unique geography, challenges, and opportunities. TGS delivers comprehensive solutions tailored to the diverse exploration needs in this region - from government support and fostering key relationships to providing critical data insights and acquisition solutions.
Our flexible portfolio is designed to meet your specific challenges and deliver the best possible outcomes.
Angola
The Angolan continental margin hosts significant proven reserves as well as untapped potential. TGS seismic data and geoscience studies provide a solid foundation to build a regional understanding of the hydrocarbon potential, by unraveling and derisking both pre- and post-salt prospectivity.
Using the latest acquisition, processing and imaging technologies, new licensing activity and TGS data for Angola are fueling a resurgence in exploration interest as significant imaging uplifts and reliable attributes reveal untapped potential. Additional geoscience studies are available for companies licensing seismic datasets, to fast-track geological understanding and evaluate petroleum systems and plays ahead of bid applications.
TGS, in partnership with ANPG (Agência Nacional de Petróleo, Gás e Biocombustíveis), has been acquiring and processing multi-client 3D and 2D seismic data in Angola for over 20 years, resulting in a library of over 69,200 sq. km of 3D data and over 50,000 line km of 2D data covering every exploration block offshore Angola.
MSGBC Basin
The MSGBC Basin, rich in hydrocarbon potential, features significant discoveries like SNE and Greater Tortue. TGS advances exploration with high-resolution 3D seismic imaging and detailed geochemical insights, providing significant opportunities in this prolific region.
The Mauritania, Senegal, Gambia, Guinea-Bissau and Republic of Guinea (MSGBC) Basin is home to several high-profile oil and gas discoveries in recent years. The palaeo-shelf edge carbonate trend extending south of the SNE field and other prospective areas north and south of the existing fields has led many explorers to the region.
TGS provides critical regional subsurface data for offshore areas across every country in the MSGBC Basin, spanning northern Mauritania to the southern Republic of Guinea and beyond. Our extensive regional 2D seismic data delivers continuous subsurface insights across the entire basin, while targeted 3D surveys focus on key exploration hotspots.
Orange Basin
The Orange Basin contains a range of Early to Late Cretaceous clastic plays sourced by the Aptian Kudu shale, which likely extends northwards into the Walvis and Lüderitz basins. The Venus, Graff and Mopane discoveries highlight the diversity of reservoirs and structural styles in the Orange Basin.
