MRST

MRST is a free open-source software for reservoir modeling and simulation. The software is mainly intended as a toolbox for rapid prototyping and demonstration of new simulation methods and modeling concepts. Like Matlab, the software is not a simulator, but offers a wide range of data structures and computational methods you can easily combine to make your own custom-made modeling and simulation tools. The functionality is organized into:

• a minimal core module offering basic data structures and functionality, and
• a large set of add-on modules offering discretizations, solvers, physical models, and a wide variety of simulators and workflow tools.

In the modules, you will find many tutorial examples that explain and showcase how the toolbox can be used to make general or fit-for-purpose simulators and workflow tools. Using Matlab for reservoir simulation may seem strange at first, but most of the tools and simulators are quite efficient and can be applied to surprisingly large and complex models, including several realistic geological models that are supplied as part of the software. For more computationally challenging cases, we recommend using the open-source Flow simulator from the Open Porous Media (OPM) initiative.

MRST has a large world-wide user base: the last releases each have between 700 and 2100 unique downloads. If you have questions about the software, we encourage you to visit our user forum, which was launched in June 2016.
