PGS’s fast-track 3D GeoStreamer data from its latest multi-client seismic survey offshore Ghana has revealed Cretaceous targets and Afina-1X reservoir analogs in the Tano Basin.
The 2019 GeoStreamer survey targeted the Ghana Tano Basin, a transform margin exploration hot spot, providing the first-ever multi-client 3D broadband data offshore Ghana.
The Upper Cretaceous play is the focus in the Tano Basin with the deep marine stacked turbidite channel and fan complexes providing excellent reservoir potential in the Cenomanian, Turonian, and Campanian, said PGS. GeoStreamer data with FWI velocity model building and AVO-compliant prestack data will allow explorers to significantly derisk deepwater exploration in this prolific basin, the company added.
‘The survey took an integrated approach to acquisition and imaging of the Upper Cretaceous play, combining the benefits of GeoStreamer broadband technology and the latest imaging workflows. Down-dip reservoir analogs of the 2019 Afina-1X discovery are well imaged in the data,’ said Joshua May, new ventures manager for Africa at PGS.
