“…8,9 These particles are exogenous particles generated by the fluid in the injection circuit and endogenous or in situ particles which coat the rock matrix like clays and other minerals. 10 These particles can be deposited in the reservoir and may consequently lead to a decrease of the reservoir permeability around the injection wells, and affect the injectivity of these wells. 11,12 During the injection at an imposed flow rate, this may lead to an increase of the injection pressure beyond the capacity of the pumps.…”

“…Such a model, originally developed by Fatt [26] to predict multiphase flow properties in porous media, describes the porosity as a network of pores connected by channels. During the last decades, it has been extensively used and extended by petrophysicists in various situations: capillarity and multiphase flow through porous media [27][28][29][30][31], pore evolution and changes in petrophysical properties due to particle capture [32], filtration combustion [33], mineral dissolution and precipitation caused by CO 2 sequestration [34] and adsorption/reaction processes [35]. Recently, Varloteaux et al [36] studied the reactive transport in porous media using a PNM.…”

Pore network model of electrokinetic transport through charged porous media

We introduce a method for the numerical determination of the steady-state response of complex charged porous media to pressure, salt concentration, and electric potential gradients. The macroscopic fluxes of solvent, salt, and charge are computed within the framework of the Pore Network Model (PNM), which describes the pore structure of the samples as networks of pores connected to each other by channels. The PNM approach is used to capture the couplings between solvent and ionic flows which arise from the charge of the solid surfaces. For the microscopic transport coefficients on the channel scale, we take a simple analytical form obtained previously by solving the Poisson-Nernst-Planck and Stokes equations in a cylindrical channel. These transport coefficients are upscaled for a given network by imposing conservation laws for each pores, in the presence of macroscopic gradients across the sample. The complex pore structure of the material is captured by the distribution of channel diameters. We investigate the combined effects of this complex geometry, the surface charge, and the salt concentration on the macroscopic transport coefficients. The upscaled numerical model preserves the Onsager relations between the latter, as expected. The calculated macroscopic coefficients behave qualitatively as their microscopic counterparts, except for the permeability and the electro-osmotic coupling coefficient when the electrokinetic effects are strong. Quantitatively, the electrokinetic couplings increase the difference between the macroscopic coefficients and the corresponding ones for a single channel of average diameter.

Critical Bursts in Filtration

Particle detachment bursts during the flow of suspensions through porous media are a phenomenon that can severely affect the efficiency of deep bed filters. Despite the relevance in several industrial fields, little is known about the statistical properties and the temporal organization of these events. We present experiments of suspensions of deionized water carrying quartz particles pushed with a peristaltic pump through a filter of glass beads measuring simultaneously the pressure drop, flux, and suspension solid fraction. We find that the burst size distribution scales consistently with a power law, suggesting that we are in the presence of a novel experimental realization of a self-organized critical system. Temporal correlations are present in the time series, like in other phenomena such as earthquakes or neuronal activity bursts, and also an analog to Omori's law can be shown. The understanding of burst statistics could provide novel insights in different fields, e.g., in the filter and petroleum industries.
