[Opm] OPM Release 2023.10 available

[Markus Blatt]

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.

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 2017 and continued his good work 
until his very last days. We owe the OPM Reference manual to him. It is 
an heroic effort with its 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.

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

If you prefer compiling the source yourself then you can either download 
the release tarballs from https://github.com/OPM or checkout the release 
branches in git via

git checkout release/2023.10

Thanks a lot for using and contributing to our software. We are valuing 
your feedback about the release. If you are having problems or find 
flaws or bugs, then please take the time to report them on github, e.g. 
in opm-simulator's issue tracker 
<https://github.com/OPM/opm-simulators/issues>. This is a good way to 
contribute to the project.

We always try to address issues posted on github if time allows. For the 
time-constrained people there is also the possibility to get commercial 
support.

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 
<https://opm-project.org/?page_id=36> or in the old manual 
<https://opm-project.org/?page_id=955> will help you together with the 
above instructions.

Best Regards,

Markus Blatt

Release manager for 2023.10
