New Hydrocarbon Plays and Prospects in the Douala Basin, Cameroon, West Africa

KILENYI, TOM, GECO Geophysical Company Ltd., Surrey, U.K.

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 methods 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 marine shales now in a far offshore position while a second one is of Early Cretaceous age and of lacustrin 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.
