Key words: relative phase permeability, capillary pressure curve, Leverett function, connate water saturation, critical water saturation, residual oil saturation, transition zone, reservoir simulation.

The article reviews the application of various methods to assign initial distribution of water and oil and their end points. A new method to justify capillary pressure curves is proposed for reservoir simulation modeling. It is demonstrated that the application of different methods to justify initial distribution of fluids and their mobility has a significant impact on calculation of development parameters.
