The overall objectives of the project are: To develop a better understanding of some important but not really well investigated rock/pore properties such as: tortuosity, pore-size distribution. surface area, and wettability, and a better insight on capillary pressure variation with respect to wettability and pore geometry of sandstone and limestone. To improve the understanding of fluid flow in porous media under conditions of secondary and tertiary recovery, through the laboratory study of the performance of enhanced recovery methods such as waterflooding. To develop empirical relationships between residual oil saturation and oil recovery at breakthrough and the uncommon rock/pore properties. Develop relationships between residual oil saturation and ultimate-oil recovery at floodout and the uncommon rock/pore properties for the different porous media. Furthermore, variations of irreducible water saturation, porosity and absolute permeability with respect to the uncommon rock/pore properties, residual oil saturation and oil recovery will be investigated. During the current quarter, the mercury porosimetry experiments on limestone core-plug samples were completed. The experimental data were also fully analyzed.
