The study utilized an integrated approach for interpretation which involved the usage of GEOLOGTM and PYTHON 3.12.4 softwares. Geolog was utilized for advanced petrophysical analysis, integrating core data to enhance reservoir characterization and interpretation. Well-log data, including gamma-ray, resistivity, porosity, and permeability logs, were processed and analyzed using Python for data manipulation, statistical calculations, and visualization. The results of the study provide crucial information for reservoir characterization, reservoir modeling and decision-making processes in hydrocarbon exploration and production activities in the Niger Delta region. Reservoir sand bodies A1 and B1 within LADE-001 well   have gross thicknesses of 138.9-130.6 ft., net-pay thicknesses of 62.5-21.5 ft. and net-to-gross (N/G) ratio of 0.0215-0.165. Effective porosity stands at 24-25%, water saturation at 28-29%, hydrocarbon saturation at 72-71%, while the volume of shale stands at 7 -8%. These parameters collectively classify reservoirs A1 and B1 as robust hydrocarbon-bearing reservoir, showcasing good thickness, moderate net-to-gross, low shale volume and favorable porosity. Sand bodies in LADE-002 well revealed gross thicknesses ranging from 139-1467 ft., net-pay thicknesses of 27.5-148 ft., N/G ratio of 0.019-0.26. The values of effective porosity range from 22 -27%, with the other parameters and their ranges expressed as; water saturation: 20-34%, hydrocarbon saturation: 66-80% and volume of shale: 6-8%. Reservoirs B2, C2 and D2 are classified as robust hydrocarbon-bearing reservoir, featuring good thickness, moderate/low net-to-gross, low shale volume and favorable porosity while reservoir A2 revealed fair to good attributes due to poor net thickness, low net-to-gross, low shale volume and favorable porosity. The delineated reservoirs are characterized by favorable porosity and permeability with a high tendency to accumulate hydrocarbons and flow during production.
