Journal ArticleDOI
Analysis of coupled gas flow and deformation process with desorption and Klinkenberg effects in coal seams
TL;DR: In this paper, a coupled mathematical model for solid deformation and gas flow is proposed and implemented using a finite element method, and the numerical code is used to solve the gas flow equation with Klinkenberg effect, and is validated by comparison with available analytical solutions.
Journal ArticleDOI
A fully-coupled hydrological-mechanical-chemical model for fracture sealing and preferential opening
TL;DR: In this article, a fully coupled hydrological-mechanical-chemical (HMC) model is developed and applied to explain enigmatic spontaneous changes in permeability that develop within a fracture in limestone under simulated in situ conditions.
Journal ArticleDOI
Effects of local rock heterogeneities on the hydromechanics of fractured rocks using a digital-image-based technique
TL;DR: In this article, a digital-image-based finite element approach is developed based on the numerical code rock failure process analysis (RFPA) to characterize micro-scale rock heterogeneity, and to understand the impact of micro scale rock heterogeneity on the macro-scale hydromechanical response of rocks.
Journal ArticleDOI
Tracer transport in a fractured chalk: X-ray CT characterization and digital-image-based (DIB) simulation
TL;DR: In this paper, a digital image-based simulation methodology is applied to evaluate the influence of heterogeneous porosity on the evolution of tracer concentrations in imaged tracer tests.
Journal ArticleDOI
Evolution of Coal Permeability during Gas Injection—From Initial to Ultimate Equilibrium
TL;DR: In this article, a displacement-based model is developed to define the evolution of coal permeability as a function of fracture aperture, and the authors conclude that the current assumption of local equilibrium may not be valid.
