Fundamentals of Fluid Flow in Porous Media


Chapter 2

Multi-phase Saturated Rock Properties

In the previous sections the physical properties of the rocks are defined in terms of single fluid system. Such a simplified case that rock in fully saturated with just a single phase is seldom found in actual petroleum reservoirs. In petroleum reservoirs, generally there are at least two phases in contact with each other. Simultaneous presentation of more than one phase in the rock requires defining new properties such as wettability, capillary pressure and relative permeability.
