Upcoming release 2017.04

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.

Opm release 2016.10

Dear OPM community,

We are pleased to announce the availability of OPM release 2016.10!

This is the second release this year, the previous release was 2016.04. The next release is expected to be 2017.04.

The release brings major improvements to the output capabilities of Flow, the fully implicit black-oil reservoir simulator. This includes improvements to summary and restart output, which is now controllable from the input deck, and also improved logging behaviour.

In addition there are numerous minor feature additions and bugfixes throughout all modules. There are only minor changes to the module structure, see the updated modules page.

We’d like to thank all who played a part in the release, for finding bugs, posting issues, writing code, reviewing, testing and packaging.

Instructions for installation are found on our download page. Binary packages are available for Ubuntu and Red Hat Enterprise Linux, instructions are available for building from source for any Linux variant or Mac OS X.

OPM release 2016.04

We are pleased to announce the availability of OPM release 2016.04. This is the first release this year, the previous release was 2015.10. The next release is expected to be 2016.10. Some features of the release include:

  • Further improved general performance for Flow, the fully implicit black-oil reservoir simulator.
  • Improvements to the extended versions of Flow: Flow-solvent handles more solvent effects and Flow-polymer has better performance.
  • Many of the upscaling programs have been cleaned up, and a few bugs have been fixed related to unit handling. Gravity is better handled in the relative permeability upscaling.
  • Major reorganization of modules, for more information see the updated modules page.

We’d like to thank all who played a part in the release, for finding bugs, posting issues, writing code, reviewing, testing and packaging.

Instructions for installation are found on our download page. Binary packages are available for Ubuntu and Red Hat Enterprise Linux, instructions are available for building from source for any Linux variant or Mac OS X.

 

 

OPM meeting in Oslo June 1-2

Dear OPM community,

We would like to invite you to participate in the 2016 OPM Meeting on June 1-2 in Oslo! We hope to welcome anybody who wants to come, please contact Atgeirr Flø Rasmussen or Tor Harald Sandve if you want to join. Please tell us as early as possible if you are planning to come to the OPM meeting so we get an overview.

We propose to make the Wednesday more user-centric and the Thursday more developer-centric, but anyone can participate on either or both days. The agenda is still open, so feel free to propose items for the agenda for either of the two days, either on the mailing list or directly to the organizers. We plan a conference dinner on Wednesday evening. The rest of the agenda will be posted as soon as we have one. Please indicate if you want to join the conference dinner.

Time: Wednesday 1st – Thursday 2nd of June 2016. We will start at 10:00 on Wednesday, and end at 15:00 on Thursday.

Location: SINTEF, Forskningsveien 1, Oslo, Norway.

Travel/Accommodation: Participants must make their own arrangements. Oslo hotels can fill up in the summer, so it is good to book early. There are no hotels in the immediate area of SINTEF, but it is easily accessible by tram (“trikk”), metro (“t-bane”) from downtown hotels (or taxi). Unfortunately, we have no funds to cover travel or accommodation. There is no fee for the meeting. Conference facilities and lunch will be provided by SINTEF.

Hope to see you in June!

Module reorganization, upcoming release

We have recently made some significant changes to the module/repository organization of the OPM software:

  • Remove the module opm-porsol, moving the content of opm-porsol into opm-upscaling.
  • Rename the module dune-cornerpoint to opm-grid. For now the contents are unchanged, but we intend to move all grid-related code into opm-grid.
  • Rename the module opm-autodiff to opm-simulators. Contents are also here unchanged for now.
  • Create a new module opm-output, containing some parts that used to be in opm-core. Ongoing work related to comprehensive and flexible output facilities will be hosted here.

The web site information about the modules may be inaccurate for a little while. We are aiming for a new OPM release at the end of April, at that time everything should be up-to-date.

Black-oil polymer simulator in OPM

Flow-polymer is a black-oil polymer simulator in OPM, which is developed by extending the black-oil simulator Flow with a polymer component. The effects of the polymer mixing are simulated  based on the Todd-Longstaff mixing model, and adsorption,  dead pore space, and permeability reduction effects are also considered. A logarithmic shear thinning/thickening model is  incorporated with the recent OPM Release 2015.10.

The following is a 3D example used to demonstrate the use of the polymer model. The data can be download from opm-data. To run the examples, just type the following command in the corresponding folders.

flow_polymer  run.param

The following image show the configuration of example. It has two production wells in the top layers and one injection well in the bottom layers.

configuration_3d_polymer

The following is the initial state of the example.

initial_saturation_3d_polymer

The flooding process begins with a 560-day pure water injection, then a 400-day polymer injection with concentration 1.0 kg/m^3. Finally, a 1530-day pure water injection is performed.

Four different kinds of configuration is used. The first one is that no polymer is injected, which is achieved by changing the polymer concentration to be 0 in the above flooding process. The second one is with polymer injection, while no shear effects are considered. The third one is with polymer injection and shear-thinning effects. The fourth one is with polymer injection and shear-thickening effects.

The following figures show the resulting evolution of bottom hole pressure and water injection rate for the injection well and the water cut for the production wells.
