PETRO-PHYSICAL CHARACTERIZATION OF "MADISON" FIELD, ONSHORE NIGER DELTA, NIGERIA

Olisa Benson Akinbode and Aduloju Bolakale Babatunde

Abstract: This report presents results of a study conducted to determine and evaluate the petro-physical properties of “MADISON” oil field, Niger delta with a view to understand their effects on the reservoirs hydrocarbon prospect and oil productivity of the field. The evaluated properties include porosity, permeability, fluid saturation, net / gross thickness and mobility which are all inferred from geophysical wire-line logs. A suite of wire-line logs comprising of gamma ray, resistivity, neutron and density logs for four wells from ‘MADISON’ oil field were analyzed for reservoir characterization of the field, but only two of the four wells possess the desired logs. The analyses carried out involve delineation of lithologies, identification of reservoirs and fluid types, wells correlation and determination of petro-physical parameters of identified reservoirs. Six reservoirs namely: A, B, C, D, E and F were delineated with their tops and bases at depth from 1902.96 m to 2389.02 m. Their analysis indicates the presence of hydrocarbon in all the reservoirs. Computed petro-physical parameters across the reservoirs gave porosity as ranging from 25.2% to 29.7%; permeability 2664.89md to 10184.26md and average hydrocarbon saturation of 82.85%, 81.05%, 76%, 71.85%, 74.95% and 56.9% reservoir A, B, C, D, E and F respectively. These results together with the determined movable hydrocarbon index (OMI) values (0.238 to 0.515) of the reservoir units suggest high hydrocarbon potential and a reservoir system whose performance is considered satisfactory for hydrocarbon production.
