A reference manual has been created for OPM Flow, the fully implicit reservoir simulator program. The manual describes the structure and keywords of the input deck format, how to run Flow, and command line parameters. We hope that it will be useful!

We would like to thank David Baxendale in particular for his hard work on the manual.

Registration

The workshop is free and open to everyone who is interested. Please register before 1st of October using the following link.

A set of three specialized simulators are now available, for the black-oil + solvent, black-oil + polymer and two-phase water + oil cases.

They are available on GitHub, and you need to build from the latest OPM master branches to get them. Their functionality will be part of the next OPM release (in October) if you prefer to install binary packages. The simulator programs are called flow_ebos_solvent (replacing flow_solvent), flow_ebos_polymer (replacing flow_polymer) and flow_ebos_2p.

Performance of the new simulators is significantly better than the existing ones, especially the specialized two-phase simulator.

It is our goal to incorporate all of these specialized simulators in a single Flow executable, which automatically will select the best variant to run each case.

A new version of ResInsight has been released!

ResInsight 2017.05 offers many new features, such as embedded flow diagnostics. For more information see the ResInsight website.

Binary packages for this new version are now available in the Red Hat Enterprise Linux (version 6 and 7) repositories as well as in the Ubuntu repository.

The OPM software suite is one of three mathematical frameworks worked on and improved through the European research project “Mathematical modelling, simulation and optimization for societal challenges with scientific computing“, or MSO4SC. The two other frameworks involved are Feel++ and Fenics. One aim of the project is to improve deployability, scalability and usability of the frameworks, especially in cloud or HPC settings. For each framework, one or more pilot applications have been chosen, and for OPM that is the reservoir simulator Flow.

Starting the coming Monday (22nd of May 2017) there is a workshop in Budapest, Hungary, organized by the MSO4SC project. The workshop web site contains information about the program and participants. It will be possible to follow most of the talks online, during or after the workshop.

If you have any questions or requests regarding OPM and the MSO4SC project please contact Atgeirr Flø Rasmussen (SINTEF).

Binary packages for ResInsight 2016.11 (the current latest release) are now available in the Red Hat Enterprise Linux (version 6 and 7) repositories as well as in the Ubuntu repository.

We expect a new ResInsight release soon, and will update the packages at that point.

Dear OPM community,

The Open Porous Media project is glad to announce that version 2017.04 of the OPM suite of simulation software has been released! Installation instructions can found on our download page.

Certainly the most significant change of this release is the introduction of the “flow_ebos” simulator. Compared to the previous “flow” simulators, “flow_ebos” uses a different approach to linearize the non-linear system of partial differential equations and as a result exhibits significantly better performance. The new simulator is intended to eventually fully replace the current family of “flow” simulators (i.e., “flow”, “flow_mpi”, “flow_solvent”, “flow_polymer”, etc.) and should already provide a proper superset of the capabilities of the “flow” simulator of previous OPM releases. For this reason, the name “flow” has been made an alias for “flow_ebos” in OPM 2017.04. If, for some reason, the previous “flow” simulator must be used, it is still shipped under the name “flow_legacy”, but we strongly encourage you to send us bug reports if you encounter any case that can be simulated using “flow_legacy” but not using “flow_ebos”.

Besides the introduction of “flow_ebos”, plenty unit tests have been added, a plethora of bugs has been fixed, well handling has been considerably improved and now supports e.g. top-hole pressure controls and vertical flow performance tables, ECL output and restart capabilities have been made much more comprehensive, and all grid related functionality of opm-core has been moved to the opm-grid module in preparation of the former module’s eventual retirement. In addition, a Docker container has been uploaded to Docker Hub to ease deployment for people who are into container technologies.

Last but not least, I would like to thank everyone who contributed to making the many changes of this release happen so smoothly. It has been a pleasure to work with you!

Have fun!

Andreas Lauser

Dear OPM community,

As you may know, OPM aims for a biannual releases and it is time for the next one, dubbed 2017.04.

Modules involved in the release (maintainers are given in parenthesis):

• opm-data (Alf Birger Rustad)
• opm-common (Atgeirr Rasmussen, Bård Skaflestad, Arne Morten Kvarving, Joakim Hove, Robert Klöfkorn, Tor Harald Sandve, Andreas Lauser)
• opm-parser (Joakim Hove)
• opm-output (Joakim Hove)
• opm-grid (Atgeirr Rasmussen, Robert Klöfkorn, Bård Skaflestad)
• opm-material (Andreas Lauser, Robert Klöfkorn, Tor Harald Sandve)
• opm-core (Atgeirr Rasmussen, Robert Klöfkorn, Bård Skaflestad)
• ewoms (Andreas Lauser, Robert Klöfkorn, Tor Harald Sandve)
• opm-simulators (Atgeirr Rasmussen, Robert Klöfkorn, Tor Harald Sandve, Andreas Lauser)
• opm-upscaling (Arne Morten Kvarving, Atgeirr Rasmussen, Bård Skaflestad)

Guidelines for the release process:

• All maintainers: Please review all open pull requests and github issues for the modules which you feel responsible for.
• All maintainers: Update the CHANGELOG for your modules. You probably should have look at the changes since the last release. You can do this using the command `git log “master@{Nov 1, 2016}..master”`.
• Cut-off date for code changes: Tuesday April 11, 2017. The master branches of all modules will be closed for non-trivial, non-regression and non-documentation merges after this, i.e., I’ll be a jerk and personally revert any merged code changes that do not fix serious problems thereafter.
• Creation of the release/2017.04 branches: Thursday April 15, 2017. To simplify the bug hunting, the master branches are only open for merging non-invasive code changes until the final version of the release is ready. Maintainers should use common sense to determine what is “non-invasive”.
• Preparation of Debian/Ubuntu and RHEL packages packages and testing based on the release branches. Arne Morten Kvarving will be responsible for this.
• Tentative date for the final version of the release: Tuesday April 25, 2017. Depending on the outcome of the packaging/testing efforts, this may be delayed by a few days.
• A corresponding release of the  ERT libraries will also be created.
• After the release: Beer (or champagne or Coke if you prefer). The master branches are fully open again.

The Norne case is an invaluable benchmark model of a real oil field in the Norwegian Sea, that is available under an open license. A new tutorial shows how to run that case with Flow, and also explains the output and visualization of the results.
