This study evaluates the petrophysical characteristics of Ogba Field in the Niger Delta Basin, Nigeria, using well log data (gamma ray, resistivity, neutron, and density logs) from two wells (Ogba-1 and Ogba-2) and core data from Ogba-4ST. The research quantifies key petrophysical parameters including shale volume, total porosity, water saturation, permeability, and net-to-gross ratios to understand reservoir properties. Results show that Ogba-1 generally exhibits lower shale content (Vsh 0.19–0.21), higher porosity (0.17–0.22), lower water saturation (0.02–0.14), and higher permeability (1851–2931 mD) compared to Ogba-2, indicating high reservoir quality. Well correlations reveal laterally continuous sand bodies interbedded with shale layers typical of a fluvio-deltaic depositional environment. Integration of well log and core data confirms distributary channel to mouth bar systems with periodic tidal influence. The study provides a practical workflow for reservoir characterization in data-limited siliciclastic settings of the Niger Delta.
