Ivory Coast – CI-506 & CI-507 Geological Insights

PGS has completed a major Quantitative Interpretation project on the Ivory Coast CI-506 & CI-507 dataset. The results highlight a working petroleum system, supported by Vp/Vs, Acoustic Impedance and AVO anomalies.

Hydrocarbon indicators can be observed in both the structural (Albian) and stratigraphic (middle Cretaceous) play systems. Numerous leads have been identified and de-risked in the area, with the system supported by recent wells such as Saphir-1 (Total).

In figure 1 we highlight the results of the quantitative interpretation (QI) that has allowed for the identification of numerous amplitude supported leads. Here we see an on-lapping system in the middle Cretaceous with a decreasing acoustic impedance and a low relative Vp/Vs ratio – both indicative of a hydrocarbon response. Leads are numerous throughout the dataset in both structural and stratigraphic settings.

In figure 2 you see fan body extractions from acoustic impedance. Numerous channel sequences, stacking on top of one another form potential reservoirs in this area. Through using a QI workflow involving AVO and inversion, PGS has been able to significantly de-risk the hydrocarbon systems in this area. Similar projects have been completed across Africa including Nigeria Transform Margin, Angola and South Africa.
