Africa has three aerially extensive, thick, deltaic systems on it’s West coast. Of these the
Congo and Niger Deltas have major commercial hydrocarbon resources. The Orange
River delta is less-explored but has already had gas and oil discoveries that indicate it’s
potential. These discoveries indicate that at least 3 hydrocarbon systems exist in the
area; in graben deposits of the early rift succession. e.g. AJ-1 well (oil), Kudu-type late
rift (gas) and in the Albian-Aptian drift succession (gas). The deepwater portion of the
delta has yet to be drilled so its potential is yet to be assessed.
