CONTRIBUTION OF THE COMBINED INTERPRETATION OF GEOPETROLEUM DATA IN THE PETROLEUM EXPLORATION PROGRAM OF THE CONGO BASIN – CASE OF THE LOKORO SUB-BASIN

Abstract

The contribution of the combined interpretation of geo-petroleum data in the oil exploration program of the central Cuvette basin “case of the Lokoro sub-basin” carried out as part of our scientific research for Diplome d'Etudes Approfondies studies (DEA). The objective of this research is to update knowledge on oil exploration in the Lokoro sub-basin. We combined and analyzed geological, geochemical and geophysical data to obtain the following results: - Static terrestrial gravity campaign in the western part in order to have information on the sedimentary cover of this zone and the geological structures; - The Kiri structure is a salt dome superimposed by fragments of granitic rock which give a signature of heavy gravity anomaly; - The highlighting of three prospective zones, Zone A, Zone B and Zone C, for which we have proposed seismic work adapted to geological realities; - The L59 seismic line of the Dekesse well was not drilled in the right place, the interpretation of this profile shows the deformation by salt tectonics, which generated geological structures of oil interest, the location of which we had proposed drilling.
