Hybrid-Dimensional Finite Volume Discretizations for Fractured Porous Media
Ivar Stefansson, Inga Berre, Eirik Keilegavlen
Over the last decade, finite volume discretizations for flow in porous media have been extended to handle situations where fractures dominate the flow. These discretizations have s…
PorePy: An Open-Source Simulation Tool for Flow and Transport in Deformable Fractured Rocks
Eirik Keilegavlen, Alessio Fumagalli, Runar Berge +2
Fractures are ubiquitous in the subsurface and strongly affect flow and deformation. The physical shape of the fractures, they are long and thin objects, puts strong limitations on…
Reactivation of Fractures in Subsurface Reservoirs - a Numerical Approach using a Static-Dynamic Friction Model
Runar L. Berge, Inga Berre, Eirik Keilegavlen
Fluid-induced slip of fractures is characterized by strong multiphysics couplings. Three physical processes are considered: Flow, rock deformation and fracture deformation. The fra…
Three-Dimensional Numerical Modeling of Shear Stimulation of Naturally Fractured Reservoirs
Eren Ucar, Inga Berre, Eirik Keilegavlen
Shear dilation based hydraulic stimulations enable exploitation of geothermal energy from reservoirs with inadequate initial permeability. While contributing to enhancing the reser…
Post-injection normal closure of fractures as a mechanism for induced seismicity
Eren Ucar, Inga Berre, Eirik Keilegavlen
Understanding the controlling mechanisms underlying injection-induced seismicity is important for optimizing reservoir productivity and addressing seismicity-related concerns relat…
High-accuracy phase-field models for brittle fracture based on a new family of degradation functions
Juan Michael Sargado, Eirik Keilegavlen, Inga Berre +1
Phase-field approaches to fracture based on energy minimization principles have been rapidly gaining popularity in recent years, and are particularly well-suited for simulating cra…
Heterogeneity Preserving Upscaling for Heat Transport in Fractured Geothermal Reservoirs
Anna Nissen, Eirik Keilegavlen, Tor Harald Sandve +2
In simulation of fluid injection in fractured geothermal reservoirs, the characteristics of the physical processes are severely affected by the local occurence of connected fractur…
Benchmarks for single-phase flow in fractured porous media
Bernd Flemisch, Inga Berre, Wietse Boon +5
This paper presents several test cases intended to be benchmarks for numerical schemes for single-phase fluid flow in fractured porous media. A number of solution strategies are co…
