The MATLAB Reservoir Simulation Toolbox (MRST) is an open-source toolbox for reservoir modeling, developed by the Computational Geosciences group at SINTEF Digital and used by researchers worldwide. It contains a wide range of tools and add-on modules for applications related to single- and multi-ph...

Temperature is a key variable for the modeling of geological CO2 storage, and any simulation model must take it explicitly or implicitly into account. In the most basic case, the assumption of reservoir temperature is simply reflected in the particular choice of fluid properties. More advanced model...

Reservoir geology has traditionally been described using corner-point grids. For such grid and general polyhedral grids, two-point flux-approximation (TPFA) schemes, or modifications thereof, are simple and robust methods which, despite grid-orientation errors and a general lack of consistency, have...

In this paper, we study the use of virtual element method (VEM) for geomechanics. Our emphasis is on applications to reservoir simulations. The physical processes behind the formation of the reservoirs, such as sedimentation, erosion, and faulting, lead to complex geometrical structures. A minimal r...

Vertical equilibrium (VE) models have proved to be attractive for simulation of \co storage scenarios. Their primary advantage is a substantial reduction in computational requirements compared to standard 3D simulation tools. In this work, we aim to include the effects of geomechanics on aquifer flo...

When injecting CO2 or other fluids into a geological formation, pressure plays an important role both as a driver of flow and as a risk factor for mechanical integrity. The full effect of geomechanics on aquifer flow can only be captured using a coupled flow-geomechanics model. In order to solve thi...
