Jaca-1 success, what next?

The recent Jaca-1 well in Sao Tome and Principe seems to have confirmed the presence of a working petroleum system in the deepwater Rio Muni Basin. The basin extends into Gabon and the 2020 reprocessed Olumi Rouge 3D in Northern Gabon shows some very similar channel bodies draped over structural highs. The 3D dataset allows interpretation of Late Cretaceous and Early Tertiary fans and channel systems in stratigraphic traps and drape features. TGS had already carried out burial- and thermal- history modelling at various depo-centres across the survey, with the source rock layers been traced from both the Ika Marin-1 and Affanga Deep-1 wells. Several pseudo wells were created by stratigraphic correlation across the 3D survey, and also allowed a thermal and burial test at the transition to the SDRs, often controversial regarding source rock maturation. The models suggested oil maturity for most of the study area. The maturation through time and expulsion models tested multiple scenarios, all confirming the presence of an oil window in the Albian-Cenomanian. Albian source rocks started generating from the Palaeocene times, when the reservoirs and the trapping mechanisms were already in place.

It will be interesting to watch and see if this play is chased in the deep-water Gabon area now the well data seems to back up the results from this modelling
