Wettability is an important parameter that significantly determines hydrology in porous media, and it especially controls the flow of water across rhizosphere—the soil-plant interface. However, influence spatially heterogeneous distributions on soil particles surfaces scarcely known. Therefore, this study investigates wettability infiltration into media. For purpose, we utilize a two-phase mode...

We report the results of a study of multiphase flow in porous media. A Darcy's law for steady multiphase flow was investigated for both binary and ternary amphiphilic flow. Linear flux-forcing relationships satisfying Onsager reciprocity were shown to be a good approximation of the simulation data. The dependence of the relative permeability coefficients on water saturation was investigated and...

three-phase (e.g., water, oil, and gas) flow in porous media, includcomplex than the corresponding two-phase curves. It is ing phase, global, and pseudo-global pressure-saturation formulathe complexity of these three-phase curves that complitions, are discussed in this paper. Comparisons of these differential cates the derivation of the global pressure-saturation form formulations are theoretic...

The control-volume discrete-fracture (CVDF) model is extended to incorporate heterogeneity in rock and in rock-fluid properties. A novel algorithm is proposed to model strong water-wetting with zero capillary pressure in the fractures. The extended method is used to simulate: (1) oil production in a layered faulted reservoir, (2) laboratory displacement tests in a stack of matrix blocks with a ...

Three models for compositional ow in porous media, varying in physical and mathematical complexity, are considered. Various formulations of the governing equations that describe these models, including phase and global pressure-saturation formulations with the total velocity and ux, are presented. Finite element methods for solving these diierential formulations are identiied.

The ability to predict multiphase fluid transport in nanoporous rocks such as shales is critical for many geoscience applications, example unconventional hydrocarbon production, geologic carbon sequestration, and nuclear waste disposal. When the pore sizes approach nanoscales, impact of molecular interaction forces between fluids solids becomes increasingly important. These can alter macroscopi...

In a previous paper (Transp. Porous Media, 55(1): 47–70), algorithms are given for computing the analytical solution to the three-phase Riemann problem. Application of those algorithms requires that the wave configuration is known. The purpose of this note is to provide a procedure to determine the wave structure for any initial and injected saturation states.
