Emerging Advances in Petrophysics: Porous Media Characterization and Modeling of Multiphase Flow

Numerical Modeling of Multiphase Flow in Porous Media

The 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. As a result, numerical simulation often offers the only viable approach to the mathematical model...

Modeling Multiphase Flow with Phase Transitions in Porous Media

A new approach to model multiphase flow in porous media with phase appearance and disappearance is to use nonlinear complementarity constraints. In addition to the standard mass balance equations for mulitphase flow, a set of complementarity constraints are added in order to handle the phase transitions. This results in a larger system of nonlinear equations, which is non-smooth in general. The...

Flow in porous media pore-network models and multiphase flow

In the last 3 years there has been a huge increase in the use of pore-scale modeling to study multiphase flow and transport in porous media. Starting from single pore models of fluid arrangements, computations of relative permeability, interfacial area, dissolution rate and many other physical properties have been made. Combined with a realistic description of the pore space, predictive modelin...

Numerical Modelling of Multiphase Flow in Porous Media

A Generalized Numerical Approach for Modeling Multiphase Flow and Transport in Fractured Porous Media

A physically based numerical approach is presented for modeling multiphase flow and transport processes in fractured rock. In particular, a general framework model is discussed for dealing with fracture-matrix interactions, which is applicable to both continuum and discrete fracture conceptualization. The numerical modeling approach is based on a general multiple-continuum concept, suitable for...
