The exploration of the Central sedimentary basin in Democratic Republic of Congo, focused on geological, geochemical and geophysical studies, as well as well drilling, started early in nineteen fifty with several foreign organizations including the Belgian firm REMINA. Coupled with field work carried out by the Congolese national oil company, this work resulted in the confirmation of the surface index at several sites, as well as the recognition of the potential mother rocks, reservoir rocks and cover rocks. In this work we contribute to the development of a geological model of the petroleum system of this sedimentary basin based on the interpretation of Bouguer anomalies. After analysis the results are represented in the form of maps. Apart from the surface index, mother rocks, reservoir rocks and cover rocks already confirmed in this area, these results have enabled the identification of places with large sediment thicknesses or central deposits and areas likely to trap hydrocarbons in this basin. Our model of this sedimentary basin allows to locate the maturation zones of the mother rocks, gives an idea of the direction of hydrocarbon migration, help identification and the location of the probable geological structures favourable to the accumulation of oil in this area.
