New seismic data acquired by GECO together with reprocessing of old data and geochemical analysis have thrown a new light on the petroleum geology of the Douala basin. The seismic data show a variety of possible traps, particularly in the offshore part of the basin, including submarine fans, buried paleohighs, salt-induced structures, updip wedging out of reservoirs, etc. Geochemical data based on advanced analytical method indicate that none of the potential source rocks encountered in wells actually matches the oils; therefore new sourcing of the known reservoirs has to be considered. Geochemical fossils indicate derivation from two sources, one probably Late Cretaceous deep marineshales now in a far offshore position while a second one is of Early Cretaceous age and of lacustrine origin. All new data indicate that the Douala basin is likely to turn out to be a prolific oil basin and not a gas basin as suggested by some earlier publications.
