N2 - Source rock geochemistry of the paleogene (Imo and Ameki Formations) strata in Bende- Umuahia and its environs, Niger Delta Basin, southern eastern Nigeria was assessed for its hydrocarbon play using walkley black wet oxidation and rock-eval pyrolysis techniques. The total organic carbon (TOC) average values for Imo and Ameki Formation are 0.86wt% and 0.74 wt%, this indicates a fair petroleum potential and organic matter concentration. The generative potential (GP) average value of 0.38mg Hc/g for the two formations studies indicates that the organic matter quality is poor. The result of hydrogen index (HI) shows a studied area that is basically type IV Kerogen. The average T max value for Imo Formation was 408.8°C ad 410.8°C for Ameki Formation, which suggest that the studied area is thermally immature. The average vitrinite reflectance (RO) values for Imo and Ameki Formation, which are 0.59R ° and 0.32R ° respectively also suggests that the area studied is thermally immature.Theplots of Rock-Eval s2 versus Toc and hydrogen index versus oxygen index indicates that the studied area is basically type IV Kerogen, while the plots of production Index versus T max and Hydrogen index versus T max indicates thermally immature for the area. Source rock geochemistry of type IV Kerogen, Thermally immature and fair petroleum potential can be assigned to the area studied.
