ABSTRACT

This work evaluated the hydrocarbon potential of Campanian source rocks of Nkporo Shale (Mgbom section) using parameters like Soluble Organic Matter (SOM), Total Organic Carbon (TOC) and Organic Matter Quality (OM) on samples taken from the section. The Nkporo Shale is dark grey in color and is highly fissile with interbeds of sandy shale, siltstone and mudstone. The investigated section exposed at Mgbom, Ebonyi State consisted of the Nkporo Shale, a formation in the Lower Benue Trough. The rocks are fairly to moderately rich in organic matter and can therefore be considered as potential source rocks. TOC analysis on sample revealed from the Mgbom Section in the range of 0.51w%-1.02wt% which exceeds the minimal amount needed for a potential source rock. The SOM ranges from 67mg/kg – 165mg/kg and the OM ranges from 77.40% – 89.30% indicating that the source rock is fairly rich in hydrocarbon content.
