- Main target : Upper Proterozoic « Schisto-Calcaire » subgroup

The “Schisto-calcaire” subgroup  could be viewed  as a source rock and as hydrocarbon reservoirs.

The 3D geological model based on gravity data and on a depositional model derived from seismic data interpretation allows to produce prospective maps of its depth and thickness.

They show that the Schisto-Calcaire  subgroup is present with thickness up to 1000m within all exploration blocks of the Cuvette Congolaise in the Republic of Congo.

- Possible fluid migration from precambrian hydrocarbon bearing formations

- Presence of large structural traps
