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.
