Finite volume discretization for poroelastic media with fractures modeled by contact mechanics
Berge, Runar Lie; Berre, Inga; Keilegavlen, Eirik; Nordbotten, Jan Martin; Wohlmuth, Barbara (Peer reviewed; Journal article, 2020)A fractured poroelastic body is considered where the opening of the fractures is governed by a nonpenetration law, whereas slip is described by a Coulomb‐type friction law. This physical model results in a nonlinear ... -
Implementation of mixed-dimensional models for flow in fractured porous media
Keilegavlen, Eirik; Fumagalli, Alessio; Berge, Runar Lie; Stefansson, Ivar (Peer reviewed; Journal article, 2019)Models that involve coupled dynamics in a mixed-dimensional geometry are of increasing interest in several applications. Here, we describe the development of a simulation model for flow in fractured porous media, where the ... -
Numerical methods for coupled processes in fractured porous media
Berge, Runar Lie (Doctoral thesis, 2019-11-15)Numerical simulations have become essential in the planning and execution of operations in the subsurface, whether this is geothermal energy production or storage, carbon sequestration, petroleum production, or wastewater ... -
Reactivation of fractures in subsurface reservoirs - A numerical approach using a static-dynamic friction model
Berge, Runar Lie; Berre, Inga; Keilegavlen, Eirik (Chapter; Peer reviewed; Journal article, 2019)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 lower-dimensional ...
