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.

From 8th to 13th of January, members of CSD/PMG traveled to Oslo, Zaragoza and Barcelona to participate in joint workshops with SIMULA Oslo, University of Zaragoza and Polytechnic university of Catalonia.

Isak Hammer is a new Ph.D. student at the Department of Mathematics and his project is part of the Center for Modeling of Coupled Subsurface Dynamics. We met him to find out more about his background and the project.

The recently published paper presents a general methodology to compute fluid phase equilibria, with persistent unknowns and general state definitions. It represents a major step towards consistent compositional flow simulation under local equilibrium assumptions.
