Journal ArticleDOI
Microcrack-based geomechanical modeling of rock-gas interaction during supercritical CO2 fracturing
TL;DR: In this article, the authors define a geomechanical model accommodating the interaction of fluid flow, adsorption-induced swelling stress, solid deformation and damage to quantify rock-gas interactions during supercritical CO2 fracturing for shale gas production.
Journal ArticleDOI
Dual-damage constitutive model to define thermal damage in rock
TL;DR: In this paper, a dual-damage thermal-mechanical model accommodating the interaction of thermal conductivity, thermally-induced deformation, rock mechanical deformation and damage is defined to define the evolution of the thermal and mechanical properties of rock during thermal treatment.
Journal ArticleDOI
The Impact of Oriented Perforations on Fracture Propagation and Complexity in Hydraulic Fracturing
TL;DR: In this paper, a fully coupled finite element method (FEM)-based hydraulic-geomechanical fracture model accommodating gas sorption and damage has been developed to better understand the interaction between hydraulic fracture and oriented perforation.
Journal ArticleDOI
W-shaped permeability evolution of coal with supercritical CO2 phase transition
TL;DR: In this article, the authors present experimental measurements of coal permeability across the CO2/SCCO2 transition over typical ranges of confining stress and pore pressures at a constant temperature of 40°C.
Journal ArticleDOI
Time–Frequency Domain Characteristics of Acoustic Emission Signals and Critical Fracture Precursor Signals in the Deep Granite Deformation Process
TL;DR: In this article, the authors used a TAW-2000 triaxial hydraulic servo testing machine and a PCI-II acoustic emission monitoring system to study the crack evolution and failure precursory characteristics of deep granite rocks under high confining pressure.
