Abstract

Reservoir characterization through the application of petrophysical evaluation of well logs was carried out over Animaux Field in the Niger Delta Basin of Nigeria. A suite of well logs from three wells (Ani-1, Ani-2, and Ani-3) were evaluated and used for reservoir characterization. Five hydrocarbon reservoirs containing oil, in three levels and oil and gas in two levels were interpreted from the three wells. Petrophysical properties (net-to-gross, thicknesses, water saturation and porosity) were estimated over five reservoirs to characterize the quality as well determine fluid typing of the reservoirs. Well correlation was carried out to find out the connections between the three wells to determine connectivity and extent. The Petrophysical analysis produced an average porosity value of 28% for the Ani-1 well for the various zones and water saturation of 31%, 21% and 20% for the E, G, and H oil zones respectively. Reservoirs E, G, H, and L have an average net pay thickness of 3.05m, 7.62m, 3.05m and 6.59m for the oil zones respectively, while the net pay thickness for reservoirs G, H and H_1 gas zones are 11.28m, 8.99m and 9.91m respectively. The reservoir parameters obtained show that the reservoirs are good and of high quality.
