This study provides accurate behaviour of petrophysical properties with depth for this formation by using Interactive Petrophysics software. The results of the analysis revealed the presence of different sand and shale units. From the analysis of the geological logs comprising gamma-ray and electrical resistivity, the Sonic, Density, Gamma, Neutron, Resistivity and Net Pay Zone value for the reservoirs of the two wells are 110.604 µs/ft., 341.659 µs/ft.; 2.180 g/cc, 2.195 g/cc; 52.782 API, 97.50API; 0.343, 0.52; 8.148 ohmm, 41.651 ohmm and 3295.5 ft, 2301.0 ft, the total porosity in the hydrocarbon bearing zone was found to range from 0.006 to 0.514, the water saturation range from 0.166 to 0.836 and the hydrocarbon saturation 0.164 to 0.834. Good well-to-well lithology correlation was established across the fields studied. The researcher found that the bulk of the hydrocarbon encountered in the Niger Delta basin was found to be within a depth range of 5,473 – 13,381 ft (1,668.17 – 4,078.53 m). The hydrocarbon reservoirs in this study were found to be in the Agbada formation, which is in conformity with the geology of the Niger Delta, Nigeria.
