An experimental foam module has been added to OPM Flow, and will be part of release 2019.10. With this it is possible to simulate certain types of surfactant injection. Such injection stimulates formation of foam to change mobility ratios, and give better reservoir sweep.

The implemented foam model treats surfactant transported in the gas phase, and reduces the mobility of that phase depending on the surfactant concentration. In addition to mobility reduction, adsorption to the reservoir rock is included in the model. To test the foam module use the keywords, FOAM, FOAMADS, FOAMMOB, FOAMROCK and WFOAM.

The model has not been tested on anything but artificial test cases so far, it is therefore likely to have omissions and bugs. If you try it out, please give us feedback by the mailinglist, github issues or direct email! A simple test case based on SPE1 has been added to the opm-tests repository, in the directory spe1_foam.

A revised reference manual for OPM Flow is now available. Compared to the revision from January, this is a massive update. There is of course the relentless efforts of documenting all the new functionality. What makes this massive is however the inclusion of file format documentation on the output side. You will find EGRID, INIT and RESTART files documented in Appendix D. Another huge thanks to David Baxendale for his relentless efforts keeping the manual in great shape!

Dear OPM community!

We are happy to announce the 2019.04 release. Binary packages are available for Ubuntu Linux 16.04, 18.04 and 18.10 as well as Red Hat Enterprise 6 and 7.

As for the last release, we have been forced to disable MPI for the Ubuntu 18.04 package. If you want to run Flow in parallel you must use another version of Ubuntu, or compile it yourself.

The release manager for this release was Arne Morten Kvarving.

Most of the presentations from the recent OPM Summit in Utrecht are now available on the talks page.

A program for the OPM Summit in Utrecht is now available.

Dear OPM community,

We would like to invite you to participate in the 2019 OPM Summit on January  24th and 25th  in The Netherlands! This year the event will be hosted by TNO and we hope to welcome all of you in Utrecht. The details of the event are as follows:

*   Location:            Princetonlaan 6, Utrecht, The Netherlands
*   Dates/Time:      24th and 25th of January 2019. Start: 10:00 on Thursday and end at 15:00 on Friday
*   Fees:                   There are no fees for the meeting, Conference facilities and food will be provided by TNO

Please let me, Rohith Nair (rohith.nair@tno.nl), or Frank Wilschut (frank.wilschut@tno.nl) know as early as possible if you are planning to join the summit, so that we can make the necessary arrangements. We plan to make Thursday (24th) more user centered and Friday (25th) more developer focused, however the agenda is flexible and you can participate on either or both days. The agenda and the presentation slots for the meeting are still open so you are welcome to propose items you would like to share with the rest of the OPM community. If you would like to make a presentation please make the same request to the organizers with a title, authors and a paragraph describing the talk, preferably before 15 January. The agenda will be published on the website and to the participants as soon as it has been set. There will also be a conference dinner on the evening of the 24th (Thursday); in your reply please indicate if you would like to join the dinner.

Travel/Accommodation: Participants must make their own arrangements. Our office is on the university campus, but we recommend hotels in the city center or near the central train station (e.g. the NH and Apollo hotels). From the city center, TNO is easily accessible by bus or taxi.

Looking forward to seeing you here!
The Organizers (Rohith Nair and Frank Wilschut)

A revised reference manual for OPM Flow is now available. Compared to the revision from November, broken links are fixed and errors in the “Running Flow” section have been fixed. We would like to thank David Baxendale for his relentless efforts keeping the manual in great shape!

Happy reading and happy new year!

A new version of ResInsight has been released, for more information about version 2018.11 see the announcement on 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 (ppa).

An up-to-date reference manual for OPM Flow is now available. The manual describes the structure and keywords of the input deck format, installation, how to run Flow, and command line parameters. All implemented functionality to date is included. We hope that it will be useful!

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

Dear OPM community,

we are happy to announce the 2018.10 release. Binary packages for Red-Hat Enterprise Linux 6 and 7 and Ubuntu 16.04 and 18.04 are available for download.

In addition to the usual list of fixes and improvements two significant improvements include:

1. flow can now write restart files which can be used to restart eclipse.
2. Performance has been improved significantly, on selected field models flow is significantly faster than eclipse.

Due to problems with the Zoltan package we have unfortunately been forced to disable MPI for the Ubuntu 18.04 package. We are looking into this, and if possible we will make updated packages at a later stage.
