Abstract Engineered water injections have gained a lot of interest as an economic and effective method improving the oil recovery. However, complexity physicochemical interactions between brines various compositions, rock has led researchers to provide multiple ways explain this phenomenon. In work, we evaluate previously suggested mechanisms, namely wettability alteration emulsification, again...

Direct numerical simulation (DNS) yields the highest fidelity predictions of mechanical deformation at pore scale, but is prohibitively expensive for analyzing large or many samples. Discrete element methods (DEM) are an efficient alternative, limited to granular media and incapable estimating controlling prediction errors. We present a pore-level multiscale method (PLMM) that approximates DNS ...

Direct simulation at the pore-scale is crucial to unravel rarefaction effect on gas transport in tight porous media. To satisfy dual demands modeling accuracy and computation effort, an appropriate method must be chosen. This work, therefore, evaluates four numerical methods for rarefied flows a two-dimensional (2D) model media over wide range of rarefaction. These are incompressible Navier-Sto...

The particles, water and oil three-phase flow behaviors at the pore scale is significant to clarify dynamic mechanism in particle flooding process. In this work, a newly developed direct numerical simulation techniques, i.e., VOF-FDM-DEM method employed perform of several different processes after flooding, which are carried out with porous structure obtained by CT scanning real rock. study on ...

This study introduces PoreFlow, a pore-network modeling tool capable of simulating fluid flow and multi-component reactive and adsorptive transport under saturated and variably saturated conditions. PoreFlow includes a variety of modules, such as: pore network generator, drainage simulator, calculation of pressure and velocity distributions, and modeling of reactive solute transport accounting ...
