Monolithic and splitting solution schemes for fully coupled quasi-static thermo-poroelasticity with nonlinear convective transport
Brun, Mats Kirkesæther; Ahmed, Elyes; Berre, Inga; Nordbotten, Jan Martin; Radu, Florin Adrian (Journal article; Peer reviewed, 2020)This paper concerns monolithic and splitting-based iterative procedures for the coupled nonlinear thermo-poroelasticity model problem. The thermo-poroelastic model problem we consider is formulated as a three-field system ... -
Numerical modeling of wing crack propagation accounting for fracture contact mechanics
Dang, Hau Trung; Keilegavlen, Eirik; Berre, Inga (Journal article; Peer reviewed, 2020)As a consequence of shearing, wing cracks can emerge from pre-existing fractures. The process involves the interaction of sliding of the existing fracture surfaces and the tensile material failure that creates wing cracks. ... -
Numerical Modelling of Convection‑Driven Cooling, Deformation and Fracturing of Thermo‑Poroelastic Media
Stefansson, Ivar; Keilegavlen, Eirik; Halldorsdottir, Sæunn; Berre, Inga (Journal article; Peer reviewed, 2021)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 heat transfer. ... -
PorePy: an open-source software for simulation of multiphysics processes in fractured porous media
Keilegavlen, Eirik; Berge, Runar Lie; Fumagalli, Alessio; Starnoni, Michele; Stefansson, Ivar; Varela, Jhabriel; Berre, Inga (Journal article; Peer reviewed, 2021)Development of models and dedicated numerical methods for dynamics in fractured rocks is an active research field, with research moving towards increasingly advanced process couplings and complex fracture networks. The ... -
Postinjection Normal Closure of Fractures as a Mechanism for Induced Seismicity
Ucar, Eren; Berre, Inga; Keilegavlen, Eirik (Peer reviewed; Journal article, 2017-10-04)Understanding the controlling mechanisms underlying injection-induced seismicity is important for optimizing reservoir productivity and addressing seismicity-related concerns related to hydraulic stimulation in Enhanced ... -
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 ... -
Simulation of Reactive Transport in Fractured Porous Media
Banshoya, Shin Irgens; Berre, Inga; Keilegavlen, Eirik (Journal article; Peer reviewed, 2023)Numerical simulations of reactive transport in fractured porous media require the solution of coupled physical and chemical processes that depend on the fractures. Such coupled processes are described by a system of nonlinear ... -

Two-level simulation of injection-induced fracture slip and wing-crack propagation in poroelastic media
Dang, Hau Trung; Berre, Inga; Keilegavlen, Eirik (Journal article; Peer reviewed, 2022)In fractured poroelastic media under high differential stress, the shearing of pre-existing fractures and faults and propagation of wing cracks can be induced by fluid injection. This paper presents a two-dimensional ... -

Lipovac, Veljko; Duran Triana, Omar Yesid; Keilegavlen, Eirik; Radu, Adrian Florin; Berre, Inga (Journal article; Peer reviewed, 2024)In the unified flash procedure, a persistent set of unknowns and equations are solved in equilibrium calculations, allowing for simultaneous phase stability and split calculations. For fluids in a subcritical thermodynamic ... -
Upscaling of Nonisothermal Reactive Porous Media Flow under Dominant Péclet Number: The Effect of Changing Porosity
Bringedal, Carina; Berre, Inga; Pop, Iulio Sorin; Radu, Florin A. (Peer reviewed; Journal article, 2016)Motivated by rock-fluid interactions occurring in a geothermal reservoir, we present a two-dimensional pore scale model of a thin strip consisting of void space and grains, with fluid flow through the void space. Ions in ... -
Upscaling of the Coupling of Hydromechanical and Thermal Processes in a Quasi-static Poroelastic Medium
Brun, Mats Kirkesæther; Berre, Inga; Nordbotten, Jan Martin; Radu, Florin Adrian (Peer reviewed; Journal article, 2018-08)We undertake a formal derivation of a linear poro-thermo-elastic system within the framework of quasi-static deformation.
