Abstract
The stratigraphic framework and reservoir distribution are essential factors controlling the accumulation of petroleum in the Miocene Congo Fan. Analysis of cores, well logs, and seismic data suggest that the submarine fan autocycle (genetic cycle) is presented by sequence of slump, debrite, densite currents, and turbidites, whereas allocycles (long-term cycles) may be composed of several autocycles (short-term cycles) that, appear as a stacking pattern or retrogradational fan. Scour surfaces at the base of gravity flow channel, stable hemipelagic mudstone section, and the surface between fan retrogradation and progradation can be used for the correlations.
