A classification of HDR models by their representation of the reservoir geometry is presented
together with the 'building-block'sub-processes which embody much of the coupled physics …

This paper presents a three-dimensional (3D) numerical model of multifracture hot dry rock
(HDR) systems using coupled thermo-hydro-mechanical (THM) modelling processes …

This study examines heat transfer during forced water circulation through fractured
crystalline rock using a fully 3-D finite-element model. We propose an alternative to strongly …

In the study of heat extraction by circulating water in a fracture embedded in geothermal
reservoir, the heat conduction in the reservoir is typically assumed to be one dimensional …

Heat extraction from enhanced geothermal systems (EGS) can greatly affect the behavior of
joints and other discontinuities in the reservoir. Fracture permeability can change in …

Strong heterogeneity does exist in engineered heat reservoirs of enhanced geothermal
systems (EGSs) due to different rock formation, pre-existence of natural fractures and …

In the numerical simulation of heat extraction by circulating water in a fracture embedded in
geothermal reservoir, the heat conduction in the reservoir is typically assumed to be one …

The modeling and prediction of heat transfer in fractured media is particularly challenging as
hydraulic and transport properties depend on a multiscale structure that is difficult to resolve …

During fluid injection in enhanced geothermal systems, thermo‐mechanical processes can
play an important role. In fact, the phenomena of reservoir seismicity and the variation of …

Enhanced geothermal systems create fractured reservoirs to extract economic quantities of
heat from low-permeability and/or low-porosity geothermal resources. Convective heat …
