Mineralogy Controls on Injection‐Induced Fault Slip Open
Fault rocks vary in mineralogy but understanding the role of mineralogy in injection‐induced fault slip behavior remains challenging. We conduct laboratory fluid injection experiments on representative faults with distinct surface mineralo…
Reactivation of heterogeneous shear veins during reservoir stimulation: Fracture interaction, stress perturbation, and induced seismicity Open
Fault zones can be highly lithified, often manifesting as veins or cemented faults. Understanding vein structures and their dynamic response to reservoir stimulation is essential for managing anthropogenic earthquakes; however, this remain…
Failure characteristics analysis of the inclined interlayer during water‐soluble cavity construction of underground salt caverns for large‐scale energy storage Open
In the process of water‐soluble cavern construction of salt cavern energy storage, since the interlayer does not dissolve in water easily, sudden collapse will cause engineering accidents such as bending and damage of the inner tube of the…
Formation and evolution of shear structures in sheared granular gouge Open
SUMMARY Fault cores have layered shear structures that evolve with time. Probing details of the accompanied gouge grain breakage and granular flow can unveil the complex evolving mechanism of fault. Here, irregular breakable grains are inc…
Thermal damage in crystalline rocks: the role of heterogeneity Open
Accurately evaluating the impact of microstructural heterogeneity on thermal damage and failure mechanisms in crystalline rocks is crucial for geothermal energy development and the establishment of nuclear waste repositories. However, in t…
Evolution of Principal Slip Zone in Sheared Granular Fault Open
The natural faults show a spectrum of slip modes due to different geological conditions. How the principal slip zones (PSZs) evolve in these faults remains a puzzle. Here, a series of numerically simulated sheared granular faults that inco…
Pore network modelling of CO2-shale interaction for carbon storage: Swelling effect and fracture permeability Open
Underground CO2 storage is a key strategy to achieving net-zero targets by 2050, which requires gigatonne-scale containment of gaseous CO2 in geological formations. Shale rocks play a role in both trapping CO2 and preventing its escape, th…
Grain-based DEM modelling of mechanical and coupled hydro-mechanical behaviour of crystalline rocks Open
Mineral grains serve as the basic units of rocks. Understanding rock materials at the grain-scale level allows us to unveil the underlying fundamental mechanisms, thereby facilitating the development and innovation of engineering solutions…
Effect of water pressure on time-dependent permeability characteristics of sand conditioned with foam and bentonite slurry Open
During earth pressure balance shield tunnelling in water-rich sandy ground, both foam and other conditioning agents, such as bentonite slurry, are injected to prevent water spewing. Permeability tests were conducted to investigate how wate…
Review of discrete fracture network characterization for geothermal energy extraction Open
Geothermal reservoirs are highly anisotropic and heterogeneous, and thus require a variety of structural geology, geomechanical, remote sensing, geophysical and hydraulic techniques to inform Discrete Fracture Network flow models. Followin…

Impact of Pile Punching on Adjacent Piles: Insights from a 3D Coupled SPH-FEM Analysis Open
Pile punching (or driving) affects the surrounding area where piles and adjacent piles can be displaced out of their original positions, due to horizontal loads, thereby leading to hazardous outcomes. This paper presents a three-dimensiona…

Rupture Of Veined Granite In Polyaxial Compression: Insights From Three‐Dimensional Discrete Element Method Modeling Open
Granite formations have been frequently involved in subsurface energy‐related activities such as radioactive waste disposal, oil, and gas storage. This is principally because of their mechanical stability, low permeability, and high corros…
