  The reservoir properties of over six hundred sand units penetrated by four exploratory oil wells (Zy-01, Kt-01, Ks-01 & Kd-01) in the Nigerian sector of the Chad Basin Northeastern Nigeria was carried out using the PRIZM GeoGraphix software. Results of the evaluation show that eighty-seven sand units have good reservoir properties for all the wells. Their sand thicknesses are between -1 m and -160 m while averages of effective (φE), density (φD) and sonic porosities (φS) are between 10 & 41%, 10 & 54% and 10 & 89% respectively. These porosity results are fair to very good. Average shale volume content (Vshl) is between 23% & 67%, these values are beyond the acceptable limit in reservoirs. The averages of permeability (k) and fluid saturation (SwA & Sh) are between 15md & 7477.8md, 11% & 71% and 29% & 89% respectively. The permeability va.. View More»
