Rift basin play evidence of a working hydrocarbon system from oil seeps on the island and satellite data showing seeps in the offshore area. The Exclusive Economic Zone (EEZ) has a lower Cretaceous succession increasing the likelihood that viable source rocks equivalent to those in Gabon extend into the EEZ.

Prospective targets:

– tilted block highs associated with the half-graben development; and

– draping of sandstone reservoirs over the underlying tilted block of the distal equivalent of turbidite fans that extend into the EEZ from Gabon and Equatorial Guinea.
