| The main objective of the present study aims to evaluate the different properties of the Late Miocene Abu Madi Reservoir in West Al Khilala Field. The petrophysical evaluation of Abu Madi Reservoir in W. Al Khilala-2 and W. Al Khilala-5 wells in the study area reveals distinctive reservoir characteristics. In W. Al Khilala-2, a sandstone interval with hydrocarbon shows was identified between depths of 9920 to 10090 FT.MD. It features a gross reservoir thickness of 170 FT and a net thickness of 114.5 FT. Effective porosity ranged from 15.4% to 26%, with a shale content of approximately 14%. This consistent lithological homogeneity suggests favorable reservoir quality. Conversely, W. Al Khilala-5 exhibits a hydrocarbon-bearing interval, showcasing 58.5 FT of gross sandstone thickness between depths of 10221.5 and 10280 FT.MD. The net pay thickness is 23 FT., with an average effective porosity of 19.4% and water saturation ranging from 39.1% to 73.5%. Notably, resistivity readings exhibit significant variation, forming a funnel shape, while the shale content remains relatively low at about 11.3%. For W. Al Khilala-2, the reservoir characterized by subfeldspathic arenite with variable hydrocarbon and water saturation levels. In W. Al Khilala-5, sandstone predominance is observed, albeit with decreased porosity due to the presence of siltstones and poorly sorted sandstone facies. Petrographic analysis reveals significant detrital components such as quartz, feldspar, glauconite, lithic fragments, micas, and heavy minerals. Authigenic components like calcite, quartz overgrowths, kaolinite, siderite, chlorite, and illite contribute to pore space alteration and porosity reduction. | ||||
