Description:
Multiphase flow and transport of compositionally complex fluids in geologic media is of importance in a number of applied problems which have major social and economic effects. n petroleum reservoir engineering efficient recovery of energy reserves is the principal goal. nfortunately some of these hydrocarbons and other organic chemicals often find their way unwanted into the soils and groundwater supplies. emoval in the latter case is predicated on ensuring the public health and safety. n this paper, principles of modeling fluid flow in systems containing up to three fluid phases (namely, water, air, and organic liquid) are described. olution of the governing equations for multiphase flow requires knowledge of functional relationships between fluid pressures, saturations, permeabilities which may be formulated on the basis of conceptual models of fluid-porous media interactions. echanisms of transport in multicomponent multiphase systems in which species may partition between phases are also described, and the governing equations are presented for the case in which local phase equilibrium may be assumed. umber of hypothetical numerical problems are presented to illustrate the physical behavior of systems in which multiphase flow and transport arise.
