TGS has won another contract for regional scale seismic acquisition in the Sub-Saharan African segment of the South Atlantic.
The Norwegian geophysical behemoth has signed an agreement with the Petroleum Commission, Ghana, to create a new offshore “2D-cubed project” across the Keta Basin, offshore Ghana.
TGS is busy on the continent; it is working on a vast processing project offshore Liberia;two large acquisitions in Nigeria; a specific block-focused four dimensional (4D) acquisition offshore Angolaand an extra-large, multi basin acquisition in Equatorial Guinea.
The Keta basin project, which is ‘Phase 1 of the Gulf of Guinea 2D-cubed’, will use 5,500square kilometres of three dimensional (3D) data and over 14,700 kilometres of two dimensional (2D) data from multiple surveys as input to create a 25,300 sq km 2D-cubed project spanning both the shelf and deepwater areas of the Keta Basin, offshore Ghana.
The final products are expected in the first quarter of 2027.
“TGS’ 2D-cubed technology generates a single, structural conformable 3D seismic volume from existing multi-vintage 2D and 3D data, using an advanced interpolation workflow to fill the gaps between lines and suppress legacy migration artifacts”, the company explains. “The result is a continuous, modern-quality 3D dataset that will provide valuable insight to explorers and support opportunity screening across the area”.
TGS says that the consequent generated data will give explorers “a single, unified subsurface view of one of Africa’s most promising underexplored margins”.
For companies evaluating the Keta Basin – home to one of the largest underexplored deepwater fan systems in Africa – this unified volume removes the burden of stitching together disparate legacy surveys. It gives licensing and exploration teams a coherent, basin-wide picture to high-grade leads and mature prospects, and to make faster, more confident decisions ahead of increasing exploration and licensing activity, without waiting for new 3D data to be shot.
