Open AccessNumerical Modelling of Convection-Driven Cooling, Deformation and Fracturing of Thermo-Poroelastic Media
Convection-driven cooling in porous media influences thermo-poro-mechanical stresses, thereby causing deformation. These processes are strongly influenced by the presence of fractures, which dominate flow and ...

Reactivation of Fractures in Subsurface Reservoirs—A Numerical Approach Using a Static-Dynamic Friction Model
Fluid-induced slip of fractures is characterized by strong multiphysics couplings. Three physical processes are considered: Flow, rock deformation and fracture deformation. The fractures are represented as low...

Open AccessUpscaling of the Coupling of Hydromechanical and Thermal Processes in a Quasi-static Poroelastic Medium
We undertake a formal derivation of a linear poro-thermo-elastic system within the framework of quasi-static deformation. This work is based upon the well-known derivation of the quasi-static poroelastic equat...

A finite-volume discretization for deformation of fractured media
Simulating the deformation of fractured media requires the coupling of different models for the deformation of fractures and the formation surrounding them. We consider a cell-centered finite-volume approach, ...

Open AccessHeterogeneity preserving upscaling for heat transport in fractured geothermal reservoirs
In simulation of fluid injection in fractured geothermal reservoirs, the characteristics of the physical processes are severely affected by the local occurence of connected fractures. To resolve these structur...

A level-set corrector to an adaptive multiscale permeability prediction
We consider the inverse problem of permeability estimation for two-phase porous-media flow. The novel approach is based on regularization by zonation, where the geometry and size of the regions are chosen adap...
