Pore-scale modeling of wettability alteration during primary drainage

Pore-scale modeling: Effects of wettability on waterflood oil recovery

A 2d Dynamic Pore Network Model for Modeling Primary Drainage

We present a dynamic network model to investigate the effects of capillary number and viscosity ratio on displacement patterns and fractional flow in primary drainage. This model predicts the events that are observed in the micro-model experiments, such as swelling of the wetting layers and the meniscus oscillation. Interfaces are tracked through the pore elements using a modified Poiseuille eq...

Pore-scale micro-computed-tomography imaging: nonwetting-phase cluster-size distribution during drainage and imbibition.

We investigated the cluster-size distribution of the residual nonwetting phase in a sintered glass-bead porous medium at two-phase flow conditions, by means of micro-computed-tomography (μCT) imaging with pore-scale resolution. Cluster-size distribution functions and cluster volumes were obtained by image analysis for a range of injected pore volumes under both imbibition and drainage condition...

Pore 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...

Pore-scale modeling of longitudinal dispersion

[1] We study macroscopic (centimeter scale) dispersion using pore-scale network simulation. A Lagrangian-based transport model incorporating flow and diffusion is applied in a diamond lattice of throats with square cross section whose radius distribution is the same as computed for Berea sandstone. We use physically consistent rules using a combination of stream-tube routing and ideal mixing to...
