Adaptive PlurGaussian Simulation plugin for facies modelling in RMS

Adaptive Pluri-Gaussian Simulation

The current implementation of Adaptive PluriGaussian Simulation of facies in reservoir modeling is based on code developed by Equinor. It is implemented as a plugin module to RMS 3D reservoir modeling software from Aspentech and can only be used together with this software. It is based on the method published by B. Sebacher et.al. (Journal of Petroleum Science and Engineering, Vol. 158, September 2017, p. 494-508) and is extended to handle trends in Gaussian Random Fields and multiple overlay facies. The implementation is adapted also to the FMU workflow and use of ERT (Ensemble Reservoir Tool) system for orchestration of reservoir simulations and assisted history matching.

Getting started

Pre-built plugins are available in releases. If you want to build from source, some prerequisites are necessary;

• Python¹
• Node.js² (with yarn 1 / classic)

The repo is also set up to use asdf to manage the necessary tools

asdf install

Then, execute

make build-gui

This should create a new .plugin file at the root of the repository.

Update truncation rule templates

Change examples/truncation_settings.dat as desired.

Then, run make generate-truncation-rules to update. The GUI will automatically get these rules, when it is built.

Releasing a new version

1. Create a new branch (e.g. git switch -c release/v<new version>)

2. Update the "version" field in gui/package.json

3. Add a new entry in gui/public/CHANGELOG.md for this particular version

   • To get a list of all commits since last, execute

     last_version="$(git describe --abbrev=0 --tags)"
     git log "$last_version"..HEAD --pretty=format:'* %s' > commits.log

   • From these, copy relevant (user-facing) changes into gui/public/CHANGELOG.md under appropriate headings

     ## <version>
     <Optionally some description or extra notes that the user should be aware of>
     
     ### What's new
     * <list of relevant new features, or breaking changes>
     
     ### Deprecations
     * <list of removals of user facing things>
     * <dropping support of RMS versions should go here, and (probably) in the general description>
     
     ### Fixes
     * <list of fixes that are included in this release>
     
     ### Performance
     * <list of changes that are improve the performance of the plugin>
     
     ### Technical debt
     * <list of changes that "pays down" techincal dept>
     
     ### Restructure
     * <list of things that have been moved, refactored, and otherwise changed / improved without affecting the usability or features>
     
     ### Miscellaneous
     * <list of various changes that don't fit neatly anywhere else>
     * <this can include updates to libraries that are used>    

4. Add the changes in CHANGELOG.md and gui/package.json to the commit and make new commit The commit message can be something like "feat: New release ($(make print-APS_VERSION))"

5. Tag the new commit (preferably also sign it by using -s)

   git tag -a -s -m '<A small summary of the changes in this release>' "v$(make print-APS_VERSION)"

6. Push the commit and tag (git push origin "$(git branch --show-current)" and git push --tags)

   This will trigger the workflow in .github/workflows/release.yml, which will make a new release in GitHub, and build a production version of the plugin

aps-facies's Issues

Not able to change ERTBOX grid to a new one that does not exist and should be created by APS plugin

It should be possible to edit the name of the ERTBOX grid and if the name does not correspond to any existing grid model,
then the user should have the option to create a new one and also set the number of layers of that grid model. Whne saving or closing the Job Settings window, the new ERTBOX grid should be created.

Remove deprecated folder

Some cleanup.
