The MATLAB Reservoir Simulation Toolbox

Thank you for your interest in MRST! Please click the button below to download MRST as a zip-file. New versions of MRST are published online twice a year in March and September. The current latest version is MRST 2023b, released on the 21st of September 2023. No other MATLAB toolboxes are required, and the software is actively tested with MATLAB versions from the last five years.

Once downloaded and extracted, it is sufficient to run the startup.m file in the main MRST folder from within MATLAB or Octave. To see what's new, see the release notes for MRST 2023b. If you are interested in following MRST development actively, you can go to our Bitbucket page or find us on GitHub. Need help to get started? Take a look at our list of frequently asked questions and visit our MRST User Group to connect with other users.

If you would like to be notified when a new version of MRST is released please join the MRST-announce google group. We will only send notifications of new releases (usually twice a year).

Previous releases

Previous MRST releases from the past 5 years can be found on the Previous Releases page. However, we recommend users use the latest release of MRST unless they have specific reason not to. If you are using a version of MRST less than MRST 2021a and using Octave, we highly recommend downloading the Octave compatibility module from our downloadable resources page.

Scripts from papers

Some scripts from papers published in-house (primarily relating to co2lab) have been moved out of the MRST release as we a no longer able to actively maintain them. These can be found here: https://bitbucket.org/mrst/mrst-paper-scripts/src/master/

Please note, these have been tested to run with certain versions of MRST detailed in the accompanying readme. We cannot guarantee that they will work with earlier or later versions of the software.
