Unformatted text preview: dimensional scaling group (Peclet number) and pore volumes rather than time, distance, velocity, etc. 2. (a) Use Buckley-Leverett theory for two-phase flow of oil and water in a permeable medium to describe and explain how an unsteady state relative permeability experiment is done and some of its limitations when using actual reservoir core, brine and oil. Make sketches of the fractional flow diagram, saturation profiles and relative permeability curves to support your explanation. Assume the oil viscosity is 0.8 cp and the water viscosity is 0.5 cp. (b) These limitations are eliminated if the steady state method is used. Explain why. What data are measured and how are they used to determine the steady state values of relative permeability?...
