Seismic Evidence of Type-1 Sequences in Douala/Kribi-Campo Basin, West Africa

Richard Seme Abomo, Loule Jean Pierre, Bruce R. Rosendahl

An interpretation of old and recent seismic data in the Douala/Kribi-Campo basin reveals the development, in the offshore area, of two important upper cretaceous submarine fan systems aid a pronounced tertiary submarine fan system belonging to Type-1 sequences (Van Wagoner et al 1990). They are found in both shallow and deep water depths. Their association with canyons mounths is indicative of their genetic relation with lowstand systems tracts.

From the uneven orientation of these canyons, with respect to the basement outcrop, it is implied that the basin topography (shelf break margin in the South and thust ramp margin in the North) inherited from the extensional phase of basin development, favoured the formation of the submarine fan systems.

Up to date, these submarine fan systems have not been tested by drilling. But, if they are proven to be sand prone, they may indead become valuable exploration targets, as they are in the Campos Basin in Brazil.
