Numerical modelling of convection-driven cooling, deformation and fracturing of thermo-poroelastic media
Ivar Stefansson, Eirik Keilegavlen, Sæunn Halldórsdóttir +1
Convection-driven cooling in porous media influences thermo-poro-mechanical stresses, thereby causing deformation. These processes are strongly influenced by the presence of fractu…
Hydro-mechanical simulation and analysis of induced seismicity for a hydraulic stimulation test at the Reykjanes geothermal field, Iceland
Eirik Keilegavlen, Laure Duboeuf, Anna Maria Dichiarante +8
The hydraulic stimulation of the well RN-34 at the Reykjanes geothermal field in Iceland caused increased seismic activity near the well. Here, we use this as a case study for inve…
Fault slip in hydraulic stimulation of geothermal reservoirs: governing mechanisms and process-structure interaction
Inga Berre, Ivar Stefansson, Eirik Keilegavlen
Hydraulic stimulation of geothermal reservoirs in low-permeability basement and crystalline igneous rock can enhance permeability by reactivation and shear dilation of existing fra…
A fully coupled numerical model of thermo-hydro-mechanical processes and fracture contact mechanics in porous media
Ivar Stefansson, Inga Berre, Eirik Keilegavlen
A range of phenomena in the subsurface is characterised by the interplay between coupled thermal, hydraulic and mechanical processes and deforming structures such as fractures. Mod…
Verification benchmarks for single-phase flow in three-dimensional fractured porous media
Inga Berre, Wietse M. Boon, Bernd Flemisch +23
Flow in fractured porous media occurs in the earth's subsurface, in biological tissues, and in man-made materials. Fractures have a dominating influence on flow processes, and the…
Finite volume discretisation of fracture deformation in thermo-poroelastic media
Ivar Stefansson, Inga Berre, Eirik Keilegavlen
This paper presents a model where thermo-hydro-mechanical processes are coupled to a deformation model for preexisting fractures. The model is formulated within a discrete-fracture…
