    Abstract

    High pressure micromodel studies have shed light on the physical processes occurring at the pore scale during pressure depletion in waterflooded systems. Tests performed with fluids characterized by different gas-oil interfacial tensions (IFT) have shown the important role gas-oil and gas-water IFT play during bubble formation and growth in porous media. The increasing gas-oil IFT values with decreasing pressure effect the distribution of the three phases during the process. Increasing gas-oil IFT combined with the effect of disjoining pressure in thin water films separating oil ganglia, result in delayed oil production and expulsion of water from the system below a certain threshold pressure.
