WellCompletion plugin

[lindjoha]

New plugin WellCompletion for visualizing COMPDAT data from Eclipse.

There are three data sources to this plugin meant to be exported by the FMU workflow:

• a csv file with compdat data
• a lyr file with zone->layer mapping (optional)
• a json file with well attributes (optional)

The plugin aggregates the data to a given format that is passed to the WellCompletions component in webviz-subsurface-components.

This is great @lindjoha 🎉 🚀 👏 Some initial feedback on first review - mostly small comments.

LGTM! 🚀 Minor comments only.

Two suggestions in addition to those below:

• You can change these env.variables temporarily to lindjoha and wellcompletions_testdata respectively. Then the CI tests will run towards the soon-to-be-added testdata.
  

  webviz-subsurface/.github/workflows/subsurface.yml

  Lines 74 to 79 in 91226ff

  	# If you want the CI to (temporarily) run against your fork of the testdada,
  	# change the value her from "equinor" to your username.
  	TESTDATA_REPO_OWNER: equinor
  	# If you want the CI to (temporarily) run against another branch than master,
  	# change the value her from "master" to the relevant branch name.
  	TESTDATA_REPO_BRANCH: master

• Add a "tour" to the plugin (the "?" button we have on the advanced plugins), explaining what the user is looking at.
