The upper Akata Formation is cited to be a primary source rock, providing Type II/III kerogen,[1] and a potential target in deep water offshore and possibly beneath currently producing intervals onshore. The clays are typically over-pressured due to the absence of enough porous sediments during compaction and are about 9,000 feet vertical depth below mean sea level.[2] References1. ^Owoyemi, 2004, p.16 2. ^The Niger Delta Petroleum System: Niger Delta Province, Nigeria, Cameroon, and Equatorial Guinea, Africa by Michele L.
