In recent years, plentiful in-depth studies on the physical and mechanical properties of granites after high-temperature ... Let be oil relative permeability, and let be water relative permeability. There are two ways of scaling phase permeability (i.e. effective permeability of the phase). If we scale phase permeability w.r.t. absolute water permeability (i.e. ), we get an endpoint parameter for both oil and water relative permeability. If we scale phase permeability w.r.t. oil permeability with irreducible water saturation present, endpoint is one, and we are left with only the endpoint parameter.
