TL;DR: The In situ Stimulation and Circulation (ISC) experiment at the Grimsel Test Site in Switzerland as discussed by the authors was designed to address open research questions in a naturally fractured and faulted crystalline rock mass, and two hydraulic injection phases were executed to enhance the permeability of the rock mass.
Iconography : Structure of the low permeable naturally fractured geothermal reservoir at Soultz
TL;DR: In this paper, a total of 39 fracture zones, with a general strike of N160°E, have been identified in six wells between 1400 and 5000m depth, and these fracture zones are spatially concentrated in three clusters.
Journal ArticleDOI
Distinct element method simulation of an analogue for a highly interlocked, non-persistently jointed rockmass
TL;DR: In this article, a grain-based distinct element model is used to reproduce the laboratory response of both intact and granulated Wombeyan marble, and an iterative calibration approach is developed to match the unconfined and confined strengths of the models to those of intact and Granulated marble.

TL;DR: In this article, a total of 39 fracture zones, with a general strike of N160°E, have been identified in six wells between 1400 and 5000m depth, and these fracture zones are spatially concentrated in three clusters.
Journal ArticleDOI
On the link between fracture toughness, tensile strength, and fracture process zone in anisotropic rocks
TL;DR: In this paper, the authors present experimental results on the anisotropy of the fracture toughness, Brazilian tensile strength, and the fracture process zone (FPZ) in granodiorite samples.
