Jakub Both receives funding for four years to investigate convection and dissolution during CO2 storage. For this, he will combine lab experiments, image analysis and numerical modeling.

This paper presents a coupling between the solvers PorePy and Reaktoro to simulate reactive transport in fractured porous media

In this paper, we prove the existence and uniqueness of elliptic variational inequalities coupled with a nonlinear ODE. Considering an elliptic equation in the domain allows us to include a fully nonlinear ODE on the contact surface which gives us new applications of frictional adhesion contact problems. 

PMG is participating at the conference on Computational Methods in Water Resources 2024 (CMWR).

This paper presents a modelling approach to simulate fracture deformation, propagation, and coalescence in porous media under anisotropic stress and fluid injection.

Our new Ph.D. student Isak Hammer went to visit TU Delft for the European geothermal PhD days 2024.

This paper study the impact of fractures on the unstable displacement of viscous fingers. Particular focus is given the transition from a regime where the flow is dominated by the viscous instabilities, to a regime where the heterogeneity induced by the fractures define the flow paths.

In this paper, we develop a general framework for an evolutionary variational-hemivariational inequality coupled with a differential equation. The framework is adapted to a frictional contact problem with applications in earth sciences. In here we present an approximation of the so-called rate-and-state friction law and prove that the coupled system is well-posed.
