G&G:

Extension of the Lower Miocene turbidites up to and flanking the inversion structures of the Cameroon Volcanic Line. Lower Miocene reservoir sand deposition was controlled by developing structure providing both structural and stratigraphic trapping potential. Secondary target reservoirs are imaged in the paleogene and Upper Cretaceous sections. The survey straddles part of the Bioko Deformation Zone and the Seamount Inversion Zone where large structures have formed in response to Early Miocene re-activation of fracture-zone 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. Oil sourced from Cretaceous source rocks has been encountered on the analogous Sao Tome Inversion Zone to the south.
