Elastic wave propagation in fractured media with spring-type and frictional contact deformation laws
Ingrid Kristine Jacobsen, Jan Martin Nordbotten, Ivar Stefansson +2
Elastic wave propagation in fractured media is relevant to applications such as analysis of seismic waves and non-destructive characterization of materials. Understanding attenuati…
Local Thermal Non-Equilibrium Models in Porous Media: A Comparative Study of Conduction Effects
Anna Mareike Kostelecky, Ivar Stefansson, Carina Bringedal +3
Instantaneous heat transfer between different phases is a common assumption for modeling heat transfer in porous media, known as Local Thermal Equilibrium (LTE). This assumption ma…
A Finite Volume Method for Elastic Waves in Heterogeneous, Anisotropic and Fractured Media
Ingrid Kristine Jacobsen, Inga Berre, Jan Martin Nordbotten +1
Numerical modeling of elastic wave propagation in the subsurface requires applicability to heterogeneous, anisotropic and discontinuous media, as well as support of free surface bo…
A Line Search Algorithm for Multiphysics Problems with Fracture Deformation
Ivar Stefansson
Models for multiphysics problems often contain strong nonlinearities. Including fracture contact mechanics introduces discontinuities at the transition between open and closed or s…
Flexible and rigorous numerical modelling of multiphysics processes in fractured porous media using PorePy
Ivar Stefansson, Jhabriel Varela, Eirik Keilegavlen +1
Multiphysics processes in fractured porous media is a research field of importance for several subsurface applications and has received considerable attention over the last decade.…
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…
