Induced seismicity associated with fluid injection into underground formations jeopardizes
the sustainable utilization of the subsurface. Understanding the fault behavior is the key to …

Hydrogen is a promising energy carrier for a low-carbon future energy system, as it can be
stored on a megaton scale (equivalent to TWh of energy) in subsurface reservoirs. However …

This paper mainly studied the microscopic progressive fatigue deterioration of granite under
cyclic loading. Firstly, a series of real-time computer tomography (CT) tests were conducted …

Enhanced geothermal systems (EGS) involve complex thermal–hydraulic-mechanical (THM)
coupling. The reservoir's permeability evolution and heat extraction characteristics under …

An unusual increase in seismicity rate near the development and production sites of
unconventional energy (eg, natural gas and geothermal fluids) has been attributed to …

Hydraulic fracturing is commonly used to enhance the hydraulic conductivity of geothermal,
oil, and gas reservoirs, particularly those situated in enclosed and unconventional …

The transitional normal stress of a rock joint subject to shear refers to the critical normal
stress under which the normal dilation is completely suppressed. The transitional normal …

Induced seismicity poses a challenge to the development of Enhanced Geothermal Systems
(EGS). Improving monitoring and forecasting techniques is essential to mitigate induced …

Fault zones often serve as the major fluid pathways in a variety of geo-energy systems, such
as deep geothermal systems. However, injection-induced instability of faults can sometimes …

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 …
