ABSTRACT
This study attempts to evaluate the petrophysical characteristics of the identified reservoirs within the study area. These characteristics encompass various parameters such as gross thickness, net sand, net to gross ratio, porosity, water saturation, hydrocarbon saturation, and fluid composition. Specifically, the study identified five distinct reservoirs—SAND 1, SAND 2, SAND 3, SAND 4, and SAND 5—penetrated by well Patty’s-002. Each reservoir was evaluated using gamma ray, resistivity, neutron, and density logs, with their depths ranging from 3299.40 to 3315.79ft, 3416.71 to 3436.70ft, 3531.02 to 3576.95ft, 4178.45 to 4214.90ft, and 4230.78 to 4310.14ft respectively. The recorded porosity, water saturation, and hydrocarbon saturation fall within the ranges of 0.17 to 0.26, 12% to 23%, and 77% to 88% respectively. The reservoir rock type predominantly comprises sandstones intercalated with shales, serving as both the source and seal rocks. Based on the average petrophysical parameters obtained, it can be inferred that SAND 1 and SAND 3 exhibit economic viability for hydrocarbon production while SAND 2, SAND 4 and SAND 5 contain hydrocarbons but do noy have the pay-zone capacity to be exploited economically.
