Molecular simulation of adsorption behaviors of methane, carbon dioxide and their mixtures on kerogen: Effect of kerogen maturity and moisture content
TL;DR: In this paper, the authors investigated the effect of the moisture content on the adsorption performance of CH 4, CO 2 and their mixtures in the presence of pre-adsorbed water and showed that H 2 O molecules are observed to migrate and aggregate into growing clusters at higher moisture contents.

Water adsorption and its impact on the pore structure characteristics of shale clay
Dong Feng,Xiangfang Li,Xiangzeng Wang,Jing Li,Fengrui Sun,Zheng Sun,Tao Zhang,Peihuan Li,Yu Chen,Xu Zhang +9 more
TL;DR: In this paper, water vapor adsorption on montmorillonite (Mt), kaolinite (Kaol) and illite (Il) were performed to investigate the behaviors of water adaption on shale clay, and the effect of adsorbed water on pore structure characteristics, such as apparent pore size distribution (APSD), N2 BET specific surface area (N2-BET SSA) and pore volume (PV), were investigated.

Molecular dynamics of methane flow behavior through realistic organic nanopores under geologic shale condition: Pore size and kerogen types
TL;DR: Wang et al. as discussed by the authors simulated the methane flow behavior through authentic kerogen-based circular nanopores with the use of molecular dynamics (MD) for the first time, and a novel construction method was developed to generate kerogenbased organic nanopore with desirable pore size and different kerogen types.

Apparent permeability model for real gas transport through shale gas reservoirs considering water distribution characteristic
TL;DR: In this paper, the authors employed the Beskok's models to characterize the bulk-gas transport mechanisms through circular nanotubes or slit nanopores with arbitrary aspect ratio, respectively.

An analytical model for relative permeability in water-wet nanoporous media
TL;DR: In this article, a relative permeability model for gas-water two phase flow in water-wet nanoporous media is proposed based on the continuity equation with modified non-slip boundary in a single nanotube and the pore size distribution (PSD) of the media.

Fractured shale-gas systems
TL;DR: The first commercial United States natural gas production (1821) came from an organic-rich Devonian shale in the Appalachian basin this article, which is a continuous-type biogenic (predominant), thermogenic, or combined biogenic-thermogenic gas accumulations characterized by widespread gas saturation, subtle trapping mechanisms, seals of variable lithology, and relatively short hydrocarbon migration distances.

The Permeability Of Porous Media To Liquids And Gases
TL;DR: The standard procedure for determining the permeability of porous media according to APZ Code No. 27 (first edition, October 1935) is based on the fundamental assumption that, as long as the rate of flow is proportional to the pressure gradient as mentioned in this paper.

TL;DR: In this paper, a general boundary condition that accounts for the reduced momentum and heat exchange with wall surfaces is proposed and its validity is investigated and it is shown that it is applicable in the entire Knudsen range and is second-order accurate in Kn in the slip flow regime.
