This popular 3D seismic survey is aimed to provide an understanding of this highly prolific Niger Delta and further highlighting its considerable remaining exploration potential. Additional information with regard to each individual survey is available upon request.
The Niger Delta province prolific petroleum system produces from a major regressive delta system. The primary source rock is the Akata formation, a marine shale enriched in organic matter deposited from the Paleocene to today. The main reservoir unit is the Agbada Formation.
