Predictive pore-scale modeling of two-phase flow in mixed wet media
[1] We show how to predict flow properties for a variety of porous media using pore-scale modeling with geologically realistic networks. Starting with a network representation of Berea sandstone, the pore size distribution is adjusted to match capillary pressure for different media, keeping the rank order of pore sizes and the network topology fixed. Then predictions of single and multiphase pr...
متن کاملThree-dimensional mixed-wet random pore-scale network modeling of two- and three-phase flow in porous media. II. Results.
We use the model described in Piri and Blunt [Phys. Rev. E 71, 026301 (2005)] to predict two- and three-phase relative permeabilities of Berea sandstone using a random network to represent the pore space. We predict measured relative permeabilities for two-phase flow in a water-wet system. We then successfully predict the steady-state oil, water, and gas three-phase relative permeabilities meas...
متن کاملPore Scale Modeling of Two-phase Flow
In this paper, we compare predictions of several pore-scale codes for singleand two-phase flow for the first time. Firstly, two implementations of lattice-Boltzmann method (LBM) and a finite-difference based code (FDDA) predict single-phase flow in Fontainebleau sandstone and dolomite samples. We then obtain pore-scale drainage for two fluid phase configurations using a novel level set method b...
متن کاملA New Approach for Constructing Pore Network Model of Two Phase Flow in Porous Media
Development of pore network models for real porous media requires a detailed understanding of physical processes occurring on the microscopic scale and a complete description of porous media morphology. In this study, the microstructure of porous media has been represented by three dimensional networks of interconnected pores and throats which are designed by an object oriented approach. Af...
متن کاملThree-dimensional mixed-wet random pore-scale network modeling of two- and three-phase flow in porous media. I. Model description.
We present a three-dimensional network model to simulate two- and three-phase capillary dominated processes at the pore level. The displacement mechanisms incorporated in the model are based on the physics of multiphase flow observed in micromodel experiments. All the important features of immiscible fluid flow at the pore scale, such as wetting layers, spreading layers of the intermediate-wet ...
