“…This behavior is due to the asymmetry in the gamma distribution, which is characterized by a relatively long tail at large . For most porous materials, the PSD is not symmetric, but skewed [46].…”

Apparent permeability is an important input parameter in the simulation of shale gas production. Most apparent permeability models assume a single pore size. In this study, we develop a theoretical model for quantifying the effect of pore size distribution on shale apparent permeability. The model accounts for the nonuniform distribution of pore sizes, the rarefaction effect, and gas characteristics. The model is validated against available experimental data. Theoretical calculations show that the larger the pore radius, the larger the apparent permeability. Moreover, the apparent permeability increases with an increase in the width of pore size distribution, with this effect being much more pronounced at low pressure than at high pressure.

“…Microscale models of flow in thin, highly porous media are promising; however, their implementation is not trivial. Some of the challenges include computational cost and convergence in direct numerical simulation methods (DNS) (e.g., Ahrenholz et al 2008;Palakurthi 2014;Vennat et al 2014), while computationally fast techniques (e.g., Bazylak et al 2008;Ghassemzadeh et al 2001;Ghassemzadeh and Sahimi 2004;Gostick et al 2007;Hinebaugh and Bazylak 2010;Koido et al 2008;Lee et al 2010Lee et al , 2009Markicevic et al 2007;Pan et al 1995;Wu et al 2012) need to overcome difficulties in capturing the pore size distribution (Gostick et al 2007) and computing respective entry capillary pressure (Joekar-Niasar et al 2010;Lindquist 2006;Prodanović and Bryant 2006), as well as in detecting the correct location of fluid interfaces for a range of contact angles (Frette and Helland 2010;Schulz et al 2015).…”

Computationally efficient microscale models designed to simulate multi-phase flow and characterize low-porosity media are challenged in thin, highly porous materials, primarily due to large, irregular pore spaces and inability to satisfy representative elementary volume requirements. In this article, we describe the pore topology method (PTM) and explore its capabilities to characterize a set of isotropic fibrous materials and to simulate multi-phase flow. PTM is a fast, algorithmically simple method that reduces the complexity of the 3-D void space geometry to its topologically consistent medial surface and uses it as a solution domain for single-and multi-phase flow simulations. Our results in permeability calculations, pore size distribution, and quasi-static drainage and imbibition simulations are in very good agreement with other numerical methods and analytical solutions. We expect that incorporating detailed spatial information about the porous media structure into the medial surface will enable a more accurate representation of the void space structure and of physical phenomena involved in multi-phase flow, thus expanding the applicability of PTM to a broader range of porous media, including non-fibrous materials.

“…In a previous paper (Ghassemzadeh, et al, 2001; hereafter referred to as Part I), we studied imbibition of a coating uid into a paper during the coating of its surface. To produce high-quality coating of the external surface of a paper, it is necessary for the coating uid to penetrate to some extent the paper's pore space.…”
