The lithology of the shallow aquifer at the KO site is mainly fine to medium sand consisting of 0.959 weight fractions with particle size ranging from 0.42 to 0.05 mm. The porosity, permeability and initial irreducible water saturation were estimated to be in the range of 0.366 – 0.435, 1.75*10-5 – 6.08*10-3 cm/sec and 0.151 – 0.353, respectively. The residual oil saturation determined for the KO site was in the range of 0.056 – 0.129.
