The possibility of existence of viable petroleum systems in west Congolien Basin has been subject to controversies over the last decade, given the extreme Tectonical events that underwent this sedimentary basin. Some studies have reported interesting results regarding potential source rocks and the organic matter input. Here, we report the petrophysical investigation of geological formations outcropping around Sekelolo and Kwilu/Snel, of which lithological units are likely to bear fluids, thus playing the role of oil and gas reservoir. The porosity and the permeability obtained from Laboratory analyses, range within 10-15% and >250 millidarcy respectively. Petrophysical results suggest the existence of very good reservoirs, while further studies are necessary to elucidate the maturation and preservation of organic matter from secondary alteration during the evolution of the basin.

Abstract
The possibility of existence of viable petroleum systems in west Congolien Basin has been subject to controversies over the last decade, given the extreme Tectonical events that underwent this sedimentary basin. Some studies have reported interesting results regarding potential source rocks and the organic matter input. Here, we report the petrophysical investigation of geological formations outcropping around Sekelolo and Kwilu/Snel, of which lithological units are likely to bear fluids, thus playing the role of oil and gas reservoir. The porosity and the permeability obtained from Laboratory analyses, range within 10-15% and >250 millidarcy respectively. Petrophysical results suggest the existence of very good reservoirs, while further studies are necessary to elucidate the maturation and preservation of organic matter from secondary alteration during the evolution of the basin.

Abstract: (french)
La possibilité d’existence de systèmes pétroliers viables dans le Bassin Ouest Congolien a été sujet aux controverses pendant la décennie passée, étant donné les évènements tectoniques qu’a connu ce bassin sédimentaire. Quelques études ont rapporté des résultats intéressants concernant les roches mères potentielles et la matière organique impliquée. Dans cette étude, nous rapportons l’investigation pétrophysique des formations géologiques affleurant aux environs de Sekelolo et kwilu/Snel, dont les unités lithologiques sont susceptibles de contenir les fluides, par conséquent jouant le rôle de réservoir de pétrole et de gaz. La porosité et la perméabilité obtenues à partir des analyses de laboratoire, se trouve dans l’intervalle 10 à 15% et >250millidarcy respectivement. Les résultats petrophysiques suggèrent l’existence des très bons réservoirs, cependant les études approfondies sont nécessaires pour élucider la maturation et la préservation de la matière organique contre l’altération secondaire au cours de l’évolution du bassin.
