A stochastic analysis of steady state two-phase flow in heterogeneous media
[1] We present a novel approach to modeling stochastic multiphase flow problems, for example, nonaqueous phase liquid flow, in a heterogeneous subsurface medium with random soil properties, in particular, with randomly heterogeneous intrinsic permeability and soil pore size distribution. A stochastic numerical model for steady state water-oil flow in a random soil property field is developed us...
متن کاملStochastic Analysis of Immiscible Two-Phase Flow in Heterogeneous Media
We present a stochastic analysis of immiscible two-phase flow ~Buckley–Leverett displacement! in heterogeneous reservoirs. Since the detailed spatial variabilities of reservoir properties such as permeability and porosity cannot be described deterministically, both permeability and porosity, or either, are treated as random space functions. In turn, water saturation and oil production rate are ...
متن کاملNonstationary stochastic analysis of steady state flow through variably saturated, heterogeneous media
In this study we develop a first-order, nonstationary stochastic model for steady state, unsaturated flow in randomly heterogeneous media. The model is applicable to the entire domain of a bounded vadose zone, unlike most of the existing stochastic models. Because of its nonstationarity, we solve it by the numerical technique of finite differences, which renders the flexibility in handling diff...
متن کاملA stochastic analysis of transient two-phase flow in heterogeneous porous media
[1] The Karhunen-Loeve moment equation (KLME) approach is implemented to model stochastic transient water-NAPL two-phase flow in heterogeneous subsurface media with random soil properties. To describe the constitutive relationships between water saturation, capillary pressure, and phase relative permeability, the widely used van Genuchten model and Parker and Lenhard models are adopted. The log...
متن کاملStochastic analysis of steady-state unsaturated flow in heterogeneous media: Comparison of the Brooks-Corey and Gardner-Russo models
Existing stochastic models of unsaturated flow and transport are usually developed using the simple Gardner-Russo constitutive relationship though it is generally accepted that the more complex van Genuchten and Brooks-Corey relationships may perform better in describing experimental data. In this paper, we develop first-order stochastic models for gravity-dominated flow in second-order station...
