The MATLAB Reservoir Simulation Toolbox: General introduction and application to geological CO2 storage modeling

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-phase flow modeling in the subsurface. This includes fundamental tools for gridding, visualization and equation solvers, as well as specialized software for multiscale methods, flow diagnostics, upscaling and more. In addition, a specialized module for modeling geological CO2 storage has been developed. This is a one-day, two-part course. The first part provides a general introduction to the design and functionality of MRST, whereas the second part focuses on the particular application of CO2 storage modeling. In particular, it discusses the particular challenges inherent to CO2 storage modeling (high density and viscosity contrasts, large spatial and temporal scales) and how they can be addressed using the specialized tools of the MRST-co2lab module. Both parts of the course include hands-on examples and exploration using installations of MRST on each participant's laptop. It is assumed that participants have their own MATLAB licenses, but other necessary software, data models and setup procedures will be provided to the participants by the instructors ahead of the course. Participants may choose to attend the full course, or one part only. The second part builds on the first, but loosely enough that new participants may still participate.
