Heat Recovery from Multiple-Fracture Enhanced Geothermal Systems: The Effect of Thermoelastic Fracture Interactions
TL;DR: In this article, the authors investigated the effect of thermoelastic interactions between multiple parallel fractures on energy production from a multiple-fracture enhanced geothermal system and showed that the matrix deformation significantly increases the interactions between the two adjacent fractures.

Understanding injection-induced seismicity in enhanced geothermal systems: From the coupled thermo-hydro-mechanical-chemical process to anthropogenic earthquake prediction
TL;DR: In this paper, the authors identify the recent advances in understanding and modelling of coupled thermo-hydro-mechanical-chemical (THMC) processes in enhanced geothermal systems (EGS), and apply the THMC processes for improving our ability to predict the occurrence of the anthropogenic earthquakes.

Coupled thermo-hydro-mechanical modelling for geothermal doublet system with 3D fractal fracture
TL;DR: In this article, the authors proposed a thermo-hydro-mechanical coupling model considering the deformation of fractal fractures, which is regarded as a thin elastic layer existed in the bedrock, whoes deformation depends to the bedrock and its own mechanical properties.

Hydraulic conductivity of rock fractures
TL;DR: In this article, the authors derived the cubic law of the Navier-Stokes equations for flow between smooth, parallel plates and showed that the effective hydraulic aperture is less than the mean aperture, by a factor that depends on the ratio of the mean value of the aperture to its standard deviation.

A review of algebraic multigrid
TL;DR: This paper gives a review of the first hierarchical and purely matrix-based approach, algebraic multigrid (AMG), which can directly be applied to efficiently solve various types of elliptic partial differential equations discretized on unstructured meshes, both in 2D and 3D.
