The OPM Summit 2024 will be held as previously announced in Oslo on April 9 – April 10. The venue will be “Meet Ullevaal” at Ullevål Stadion, close to the metro stop with the same name. A full program is not yet ready, but times will be as follows.

Tuesday April 9:
0930-1000: welcome and registration,
1000-1700: main program.
Wednesday April 10:
0900-1630: main program.

We are happy to announce that finally finished and published the manual for OPM Flow for the latest release: OPM Flow 2023-10.

The release notes are also available separately: OPM Flow release notes 2023.10.

This version along with older versions of the manual are available on the manual page.

This time this took a bit longer than usual. David Baxendale was responsible for the Manual and delivered great work from 2017 until 2023. He passed away last summer after a sudden and severe illness. Our thoughts are still with his wife and son. To honor him we dedicated the 2023-10 release of OPM-flow to him.

In September 2023, Matthew Goodfield took over the editing work of the manual. He was personally recommended by David and we are very thankful for that. Together with his colleagues from especially OPM-OP and NORCE (e.g. Håkon Hægland) we were able to split the manual into multiple libreoffice files stored as plain xml. Those are now available to the public under an open license in the opm-reference-manual github repository.

This year, on April 9 – April 10 the OPM summit will be held in Oslo, Norway. This is a two-day workshop that is open to all users, developers and others who have an interest in OPM. We seek contributions in the form of talks and possibly also posters, if there is sufficient interest. If you would like to contribute, participate or have questions please contact one of the members of the preliminary program committee: Eduardo Barros, TNO (eduardo.barros@tno.nl), Tor Harald Sandve, NORCE (tosa@norceresearch.no), Alf Birger Rustad, Equinor (abir@equinor.com) or Atgeirr Flø Rasmussen, SINTEF (atgeirr.rasmussen@sintef.no).

More details including venue, registration and program, will be coming later.

Atgeirr Flø Rasmussen,
on behalf of the program committee.

Dear OPM community,

It is my pleasure to announce that the 2023.10 OPM release is now ready. Thanks to all contributors for your improvements to the software and documentation, and to users for alerting us to bugs and problems.

We dedicate this OPM 2023.10 release to our colleague and friend David Baxendale. David passed away in late June 2023 after a short severe illness. Our thoughts are with his wife and son. The OPM community is very thankful for all his contributions to OPM and the fruitful discussions with him about issues with and advancements of the simulator.

David started contributing to OPM in 2016 as OPMUSER on github and continued his good work until his very last days. We owe the OPM Reference manual to him. He started this heroic effort in 2017 and it now consists of thousands of pages. We, his colleagues and friends, are and will be surely missing him with his reservoir engineering expertise and know-how, his enthusiasm, and humor.

The 2023.10 release consists of some new features and various improvements and bug fixes. Our main target was to support more keywords used for relevant fields and reducing the differences between OPM flow and the commercial simulator. These improvements include

• Added support for temperature (THERMAL) plus salt precipitation (PRECSALT) modeling in gas-water-brine (GAS-WATER-BRINE) systems
• Added support for modelling dissolved gas in water (DISGASW) and vaporized water in the gas phase (VAPWAT) in the thermal-gas-water simulator
• Support for modeling FOAM combined with SOLVENT
• partial support for WAGHYSTR keyword (Water-Alternating-Gas hystersis)
• Improvements to many user-facing error messages.
• More graceful exits for problems in parallel runs.
• Temperature is output if requested via RPTRST
• Added support for WBP, WBP4, WBP5 and WBP9 in the SUMMARY section to output well block averaged pressures for open completions
• Added support for initializing constant flux aquifers from a restart
• Added support for WBP, WBP4, WBP5 and WBP9 in the SUMMARY section to output well block averaged pressures for open completions
• Faster two-point flux-approximation introduced in the last release is now also used for linearizing gas-oil cases with energy (with diffusion) and gas-oil diffusion

Full release notes will be available with the updated manual soon. In the meantime you can take a look at our preliminary release notes. Please note that they are just a draft version right now.

Binary packages for the 2023.10 OPM release are available for RHEL 7, as well as for Ubuntu 22.04 LTS (code name Jammy Jellyfish) and 20.04 LTS (code name Focal Fossa). The Ubuntu packages may be downloaded from the OPM Project’s Personal Package Archive (ppa:opm/ppa). If you have not already included this in your package sources, you can do so with the commands:

sudo apt-add-repository ppa:opm/ppa
sudo apt-get update

Then you can install the simulator and its prerequisites using the command:

sudo apt install libopm-simulators-bin

You can install python bindings for opm via pip (https://pypi.org/project/opm/) using:

pip install opm

Please note that the new release of our OPM Reference manual still needs some time. We hope to publish it soon. In the meantime we hope that the installation instruction on the website or in the old manual will help you together with the above instructions.

Best Regards,

Markus Blatt

Here are the presentations from the webinar on simulating CO2-storage with OPM Flow that was held on September 22, 2023.

CO2 simulations in OPM Flow, an overview (Tor Harald Sandve, NORCE)

Performance acceleration for CO2 simulations (Atgeirr Flø Rasmussen, SINTEF)

CO2STORE: Case studies (Cintia G. Machado, TNO)

The recent addition of salt precipitation in Flow just received noteworthy attention in the Journal of Petroleum Technology. Unfortunately it is behind a pay wall, but everybody will at least see the start of the article here.

The manual for OPM Flow has been updated for the latest release: OPM Flow 2023.04.

The release notes are also available separately: OPM Flow release notes 2023.04.

This version along with older versions of the manual are available on the manual page.

The SPE11 CSP targeting CO2 storage simulations was recently released ( https://www.spe.org/en/csp/ ).

If you are interested in simulating the CSP using OPM Flow you can check out the open framework created by David Landa-Marbán. The framework can be used to setup and run Flow based on the description given in the SPE11 CSP.

Dear OPM community,

It is my pleasure to announce that the 2023.04 OPM release is now ready. Thanks to all contributors for your improvements to the software and documentation, and to users for alerting us to bugs and problems.

This release is dedicated to the memory of Ove Sævareid, who regrettably passed away suddenly this April. Ove was a long-standing contributor to OPM, and active up to the last. We are thankful for his contributions to the OPM community. His enthusiasm, know-how and scientific expertise will be missed by colleagues and friends.

The most significant change to OPM Flow for this release is that the simulator is now by default a lot more restrictive about accepting unsupported keywords in the input deck. Any keyword (or part of a keyword) that could potentially affect the simulation results and is not supported by OPM Flow will now prevent the simulator from running. Unsupported keywords such as ECHO/NOECHO that have no effect on the simulation will still be accepted with a warning. If you for any reason require less strict behaviour, you can use the command-line option:

--parsing-strictness=low

Adding that option will let OPM Flow ignore all unsupported keywords. In the opposite direction, using “high” instead of “low” will cause OPM Flow to stop for any unsupported keyword or parsing anomaly.

Full release notes will be available with the updated manual soon.

Binary packages for the 2023.04 OPM release are available for RHEL 7, as well as for Ubuntu 22.04 LTS (code name Jammy Jellyfish) and 20.04 LTS (code name Focal Fossa). The Ubuntu packages may be downloaded from the OPM Project’s Personal Package Archive (ppa:opm/ppa).  If you have not already included this in your package sources, you can do so with the commands:

sudo apt-add-repository ppa:opm/ppa
sudo apt-get update

Then you can install the simulator and its prerequisites using the command:

sudo apt install libopm-simulators-bin

You can install python bindings for opm via pip (https://pypi.org/project/opm/) using:

pip install opm
