This research is centered around employing 3D static modeling, utilizing 3-D seismic and well-log data, to assess the petrophysical characteristics of reservoirs within a Niger Delta field. The primary aim is to determine the extent of movable hydrocarbon resources present within these reservoirs. The seismic data, available in SEG-Y format, played a pivotal role in velocity analysis and structural modeling within the field. Sequential Gaussian simulation and sequential random function simulation techniques were instrumental in achieving this. The integration of these findings with wire-line log data allowed for the extraction of crucial petrophysical attributes like net-to- gross ratio, porosity, water saturation, permeability, and facies distribution. The structural model of the reservoir reveals the presence of distinct listric normal faults named F1 and F2, each displaying unique orientations.

Keywords : Porosity, Permeability, Water Saturation and Fault.
