In this work, phytoclasts, opaques, Amorphous Organic Matter (AOM) and palynomorphs of the Nkporo group underwent Visual Kerogen analysis. Herein, the average percent counts of phytoclasts are about 42.08%, opaques are about 34.54%, Amorphous Organic Matter (AOM) is about 16.34% and Palynomorphs are about 7.08%. The highest number of percent counts produced is found in the phytoclasts (the value of 42.08% indicating Type III kerogen and Gas Prone) and Amorphous Organic Matter (AOM) (the value of which - 34.54% - indicates Oil/Gas Prone). Thus, from the results of the visual kerogen, in the Nkporo Group, the source rock is of Type III kerogen, which is gas prone, and also Type II/III, which is Oil/Gas prone.
