Annotation:

An approach to the joint statistical regression of the experimental results of critical water saturation and displacement factor on core samples to substantiate the dependences of the end points of the relative phase permeabilities is presented. Because of the joint regression of the experimental results, the dependences for the displacement factor and residual oil saturation are clarified in the ranges of porosity and permeability, poorly provided with actual data. The form of dependencies provides the possibility of a continuous and mutually agreed description of the filtration properties of rocks, both above and below the cut-off. The resulting dependences retain their physical meaning at the limiting values of the arguments.
