G&G:
Extension of the Lower Miocene turbidites basinwards from the productive reservoirs of the Aseng and Alen fields of Blocks O & I. Lower Miocene reservoir sand deposition was controlled by developing structure providing both structural and stratigraphic trapping potential. Other target reservoirs are imaged in the Paleogene and Upper Cretaceous section. The survey straddles the Bioko Deformation Zone where large structures have formed in response to Early Miocene re-activation of fracture faults. The area falls within the influence of proven petroleum systems linked to source rocks in the Paleogene and Upper Cretaceous sections. Kitchen areas are modelled for these source intervals across the region with favourably late timing of maturation.
