The study presents a comprehensive analysis of well log data from the “XRO” oil field in the Central Swamp Depobelt of the Niger Delta, analyzing gamma ray, resistivity, neutron, density, and sonic logs to determine lithology and pore fluid content, computing geomechanical properties (bulk modulus, shear modulus, Young’s modulus, Poisson’s ratio, Vp/Vs ratio) and petrophysical parameters (porosity, permeability, water saturation, shale volume, bulk volume of water) using Interactive Petrophysics v4.6, identifying two distinct reservoir sands across five wells (RO5–RO9) with unique geomechanical and petrophysical characteristics, net pay thicknesses ranging from 234.51 ft to 993.57 ft, porosity and permeability in RO5’s sand units 1 and 2 at 0.386/0.338 and 91.36 mD/73.11 mD respectively, and high resistivity values indicating hydrocarbon presence except in RO8’s sand unit 1 where low resistivity suggests brine, thereby enhancing reservoir characterization and supporting efficient hydrocarbon development strategies.| Pages | 55-61 |
