In the failure of quasi-brittle materials such as rocks, microstuctural damage always
precedes macroscopic fracture and manifests itself in the formation of fracture process zones …

The world's primary energy requirements are supplied to a large extent by non-renewable
energy resources, which has resulted in significant anthropogenic greenhouse gas …

Shear stimulation, so‐called hydroshearing, is believed to reactivate critical or near‐critical
preexisting fractures by pressurized fluid injection, causing them to slip and dilate for …

Abstract The Fenton Hill enhanced geothermal system (EGS) test site was the first of its kind,
and interpretations of field observations from the project have influenced the past four …

In this study, we analyze a deep hydraulic stimulation of a fracture zone that was conducted
as part of the classical Fenton Hill Hot Dry Rock Program in the 1970s. At the time, it was …

The dilatant shear slip of preexisting fractures/faults by injection at pressures below the
minimum in situ stress has been recognized as an important permeability creation …

We use broadband seismic data collected within 3 km of a hydraulic fracturing (HF) well in
northeast British Columbia, Canada, to estimate the stress drop values of HF‐induced …

Fault zones are key features in crystalline geothermal reservoirs or in other subsurface
environments due to the fact that they act as main fluid pathways. An adequate experimental …

Understanding the hydraulic and frictional sensitivity of fault to different injection conditions
is one of the efficient ways to provide useful implications for fault reactivation potential …

Fractures in a rock mass have an important influence on the mechanical response and
hydraulic properties. Investigating and modeling fractures is crucial, especially with regard to …
