Abstract: Petroleum Exploration Plays of the Onshore Doula//Kribi-Campo of Cameroon, West Africa

Richard Seme Abomo

Generally, rifting and drifting phases characterize the Douala/Kribi Campo Formation. The rifting phase resulted from a progressive northward plate tectonic evolution, which extended from Late Jurassic to Neocomian-Turonian time, involving both an extensional process and strike-slip movements along fracture zones.

The drifting phase was established during the Albian period, with the first marine incursion in the basin. During this phase, sedimentation was controlled by such factors as sea level variations, drainage systems and climate.

Consequently, the onshore sector of the Douala/Kribi-Campo Basin can be subdivided into two major areas with different petroleum exploration plays.

The southern area in which the rifting phase has thick Albo-Aptian sediments of terrigenous and clastics nature. These were deposited in coalescing fan deltas, locations of which were controlled by collapsed and tilted blocks. Trangressive deposits of the drifting phase overlie the erosional surface.

In the northen area, the rifting phase consists of a system of horsts and grabens of Aptian time. The drifting phase consists of shelf sandstones and Upper Cretaceous turbiditic deposits.
