Multiphase-Flow Properties of Fractured Porous Media
Proceedings of SPE Western Regional Meeting, 1999Abstract The fluid transfer parameters between matrix and fracture are not well known. Consequently, simulation of fractured reservoirs uses, in general, very crude and unproved hypothesis such as zero capillary pressure in the fracture and/or relative permeability functions that are linear with saturation.

Multiphase Flow in Porous Media
1985We discuss in detail the observable consequences of percolation models of immiscible displacement in porous media, with emphasis on the critical behavior. At the microscopic level these include the fractal nature of the non-wetting fluid configuration in drainage, and the size distribution of the residual non-wetting clusters in imbibition.

A Continuum Approach to Multiphase Flows in Porous Media
Journal of Porous Media, 1999Using a formal volume averaging method, the author derives equations of motion for multiphase flows, applicable in packet distillation and absorption towers.

Capillary Effects and Multiphase Flow in Porous Media
Journal of Porous Media, 1998The author briefly reviews recent advances in multiphase flows involving capillarity, and discusses the measurement and interpretation of hydrodynamic coupling in cocurrent two-phase flows. The evolution of saturation profiles is described in terms of viscosity ratio and the ratio of viscous-to-capillary forces. The conditions controlling the oil blobs

Quantitative NMR Imaging of Multiphase Flow in Porous Media
Magnetic Resonance Imaging, 1992Quantitative description of multiphase flow in porous media and local saturation distributions at steady states are of fundamental importance for petroleum recovery. The use of MRI provides an unprecedented means for obtaining such information. In this paper, profile imaging techniques for quantitative evaluation of fluid saturations during flow ...

Numerical Modeling of Multiphase Flow in Porous Media
Advances in Water Resources, 1985The simultaneous flow of immiscible fluids in porous media occurs in a wide variety of applications. The equations governing these flows are inherently nonlinear, and the geometries and material properties characterizing many problems in petroleum and groundwater engineering can be quite irregular.

Simulation of multiphase flows in porous media
Transport in Porous Media, 1991The ability to numerically simulate single phase and multiphase flow of fluids in porous media is extremely important in developing an understanding of the complex phenomena governing the flow. The flow is complicated by the presence of heterogeneities in the reservoir and by phenomena such as diffusion, dispersion, and viscous fingering. These effects

Analysis of non‐isothermal multiphase flows in porous media
Mathematical Methods in the Applied Sciences, 2022We consider an initial‐boundary value problem for a degenerate fully nonlinear parabolic system modeling coupled two‐phase flow and heat transport through porous media. The two‐phase fluid system consists of incompressible wetting phase and compressible nonwetting phase, such that the density of the nonwetting phase is a function of the phase pressure ...

Multiphase Flow in Porous Media
1991In this chapter, we consider the simultaneous flow of liquids and gases through porous media. We shall assume that cohesive forces in these fluids exceed the adhesion ones, and that the fluids are immiscible and separated from each other by stable abrupt interfaces.
