Two-Phase Flow Modelling in Clay Rich Shale

Abstract

Computational fluid dynamics (CFD) have made huge strides lately and are bit by bit turning into a pervasive device in science and engineering. In this paper, we present a new mathematical model, which adequately describes single- and two-phase flow, which considers relative permeability and capillary pressure in water rich clay shale. Furthermore, we implement the two-phase flow model into COMSOL multiphysics software. From the result analysis, it is concluded that the relative permeability and capillary pressure are important properties, which describe the simultaneous movement of water and gas phase in unconventional clay-rich shale.
