Capillary pressure control was exercised over flow of gas and oil in the presence of water. The water saturations ranged from 17 to 71 percent pore volume. A method of calculating both the oil and water permeability's of a three-phase system from the easily measured gas relative permeability is presented.reportsengCopyright and other restrictions may apply.
