Rock fractures are crucial conduits for fluid flow in fractured rock masses. Three-dimensional
(3D) discrete fracture network (DFN) modeling approach, which can explicitly characterize …

Friction-permeability response of rock fractures is a fundamental issue in develo** geo-
energy extraction and storage. This review aims to summarize and promote our …

We study how the normal stiffness and the permeability of a realistic rough fracture at the
field scale are linked and evolve during its closure up to the percolation threshold. We base …

Understanding the shear-induced evolution of aperture size is critical for controlling fracture
permeability in rock engineering projects. This study reports a robust procedure to evaluate …

The permeability evolution of fractal-based two-dimensional discrete fracture networks
(DFNs) during shearing under constant normal stiffness (CNS) boundary conditions is …

Gas hydrate is considered to be one of the most promising energy sources of the 21st
century, however, with the deepening of research on hydrate resources and the acceleration …

The single-fracture seepage model is important for fracture network seepage models and
underground engineering, but the existing knowledge is insufficient for the roles of the high …

Currently, the exploration of natural gas hydrates (NGHs) is regarded as a worldwide
research focus. Due to multiple characteristics of NGH reservoirs (such as weak bonding …

Abstract A conceptual Enhanced Geothermal System (EGS) with triplet horizontal well layout
is proposed, in which the injection well is flanked by two production wells. The injection well …

Interaction between grouts and groundwater is frequently encountered in geotechnical
engineering. Based on the self-developed apparatus, it is indicated that grout washout …
