Abstract: The goal of this study is to maximize hydrocarbon reserves by evaluating reservoirs using derived petrophysical parameters, a common practice in the oil and gas industry. In order to complete this task, data (logs) from three Niger Delta onshore wells (OMA01, OMA02, and OMA 03) were used. Gamma-ray, resistivity, and neutron-density well logs were used in this study for lithology identification, fluid delineation, and hydrocarbon identification. Petrel and Rokdoc software were used for lithology identification and petrophysical analysis computation. The qualitative analysis revealed that the wells drilled through various lithologies contained sand and shale intercalations. Three in WellOMA01, Four in WellOMA02, and Two in WellOMA03, reservoirs were delineated. The field’s petrophysical analysis was also produced. Shale’s volume varies from 10% to 24%, its porosity from 14% to 26%, and its water saturation from 16% to 53%, while its permeability was relatively high. The highest hydrocarbon saturation (84%) was found in RES 01 from WellOMA03. The “OMA†field study revealed that there is a sizably high potential for hydrocarbons.
