Transmissivity of rock fractures: Normal loading and shear reactivation

Monia Woehner

Enhanced Geothermal Systems represent a major field of study in the context of renewable energy resources. To create extractable energy from those reservoirs, a high enough fluid flow rate for production needs to be achieved. This fluid flow rate is direct ...

Thermal influences on macroscale rock damage

Fracture processes in rock have widespread implications in the geohazard, geomorphologic, and civil and mining engineering communities. Propagation of fractures reduces overall rock mass strength, can lead to large-scale gravitational instabilities, and ca ...

Fracture toughness of sandstone under dry, saturated and immerged conditions

Salma Lemghari

Water-induced strength reduction is one of the most critical causes of rock engineering disasters. Understanding the influence of water on the fracture toughness of rocks is necessary for rock fracture mechanics and rock engineering applications such as mi ...

Hydraulic fracturing is frequently used to increase the permeability of rock formations. This can be done by creating new fractures as usually done for hydrocarbon extraction or extending and opening fractures as usually done in Enhanced Geothermal Systems ...

Numerical investigation on water exchange of shale samples

Alessio Ferrari, Sara Incollingo

Interest in the hydraulic and mechanical characterization of shales has grown in recent years, because of their application in the context of energy geotechnics. In the frame of nuclear waste disposal shales are considered as host formations for the placem ...

Transition from a radial to a 3D buoyancy-driven hydraulic fracture

Brice Tanguy Alphonse Lecampion, Andreas Möri

Magmatic dikes are a naturally occurring type of fluid-driven fractures (Rivalta et al. 2015) propagating in the lithosphere due to buoyant forces emerging from the density difference between the host material and the injected fluid (more precisely the dif ...

Fully-coupled 3D modelling of magmatic dike Propagation – finite pulse release from a point source

Brice Tanguy Alphonse Lecampion, Andreas Möri, Haseeb Zia

Magmatic dikes are a naturally occurring type of fluid-driven fractures [1] propagating in the lithosphere driven by buoyancy (more precisely by the difference between the in-situ minimum horizontal stress gradient and the magma weight). Fully-coupled mode ...

This report presents numerical results obtained through MATLAB simulations aiming at characterising the singularity of the stresses at a crack tip in a sparse, regular, linear elastic structure. The simulation algorithm is explained and validated by the re ...

Growth of a radial hydraulic fracture accounting for the viscous fluid flow in a rough cohesive zone

Brice Tanguy Alphonse Lecampion, Dong Liu

We investigate the growth of an axisymmetric hydraulic fracture in an impermeable quasi-brittle material accounting for the presence of a fluid lag. The process zone is simulated using a linear softening cohesive zone model and is characterized by an incre ...

Propagation of a plane-strain hydraulic fracture accounting for the presence of a cohesive zone and a fluid lag

Dong Liu

We revisit the problem of the propagation of a plane-strain fluid-driven fracture in a quasi-brittle impermeable medium accounting for the presence of a fluid lag. The fracture process zone is simulated using a linear-softening cohesive model while lubrica ...
