A Triangular Model for Three-Phase Flow

In this paper some numerical experiments with a recently proposed model for the flow of water, oil and gas in a porous medium are discussed. We consider the case of incompressible flow and neglect cappilary effects. In many oil reservoars the three phases are in contact with each other. The most important parameters describing the flow are the three-phase relative permeabilities. Unfortunately, these data are typkally very difficult to measure and is often not available.
