New 3D GeoStreamer data over blocks CI-526/707/708 combined with a reprocessing of data over CI-602/603, targets the deepwater area offshore Côte d'Ivoire. Modern imaging techniques unveil key plays in this West African Transform Margin exploration hotspot.
Upper Cretaceous aged turbidite channel and fan complexes are the primary target in the deepwater Côte d'Ivoire Basin. Over 12 000 sq. km of modern 3D coverage provides an unprecedented view on the distribution and detail of depositional systems held in stratigraphic pinch-out traps.
Broadband acquisition paired with modern processing workflows reveal this underexplored area of the Côte d'Ivoire Basin. Clearer imaging of subtle depositional features is provided with increased high and low frequency content.
