PGS has completed imaging of the first-ever multi-client 3D seismic survey offshore Ghana. The broadband KPSDM data reveals sharper imaging of prolific Cretaceous reservoir targets.
The 3D GeoStreamer survey acquired in 2019 targets the Tano Basin, an area that has recently received high-profile exploration success with the Afina-1X discovery well. Down-dip analogs of this play are well imaged with increased high- and low-frequency content providing sharper imaging and improved resolution of stratigraphic traps.
The survey focuses on the Upper Cretaceous play, revealing a deep marine turbidite channel and fan complexes that provide excellent reservoir potential in the Cenomanian, Turonian, and Campanian formations. Deeper syn-rift plays are also well imaged with multiple Albian-aged leads identified in tilted fault blocks and inversion anticlines.
The company said that GeoStreamer data with Full Waveform Inversion velocity model building and AVO compliant prestack data will allow explorers to ‘significantly derisk deepwater exploration in this prolific basin.’
