The history of reservoir stimulation to extract geothermal energy from low permeability rock
(ie so-called petrothermal or engineered geothermal systems, EGS) highlights the difficulty …

This work reviews various studies of hydraulic and pneumatic tomography for estimation of
flow properties of fractured geologic media with hydraulic and pneumatic tomography. The …

We introduce an approach for the stochastic characterization of the geometric and hydraulic
parameters of a three‐dimensional (3D) discrete fracture network (DFN) and for estimating …

Field tracer experiments were conducted to examine tracer transport properties in a fracture‐
dominated crystalline rock mass at the Grimsel Test Site, Switzerland. In the experiments …

In fractured rocks, the amplitudes of propagating seismic waves decay due to various
mechanisms, such as geometrical spreading, solid friction, displacement of pore fluid …

Six hydraulic shearing experiments have been conducted in the framework of the In-situ
Stimulation and Circulation experiment within a decameter-scale crystalline rock volume at …

Tracer tests were conducted as part of decameter-scale in-situ hydraulic stimulation
experiments at the Grimsel Test Site to investigate the hydraulic properties of a stimulated …

Fractures serve as highly conductive preferential flow paths for fluids in rocks, which are
difficult to exactly reconstruct in numerical models. Especially, in low-conductive rocks …

As part of the In-situ Stimulation and Circulation (ISC) experiment, hydraulic fracturing (HF)
tests were conducted in a moderately fractured crystalline rock mass at the Grimsel Test Site …

Volcanoes represent one of the most critical geological settings for hazard modelling due to
their propensity to both unpredictably erupt and collapse, even in times of quiescence …
