Hydrocarbon Potential and Thermal Maturity of …

Nkporo Shale in the Anambra basin and Afikpo syncline was reported to contain mainly terrestrially derived organic matter that is essentially gas prone. The organic facies, hydro carbon source potential and reconstruction of the depositional environment of the Campano-Maastrichtian Nkporo Shale have been studied by Akaegbobi and Schmitt [7] .
