Cycle 0: BHP-controlled and/or (Reservoir)Rate-imposed wells.

[FoamScience]

Features to be added

• Base well object with generic well drives
• Generic well model class with support for well groups
• BHP-controlled and Rate-imposed well drives implementations.
• Peaceman implementation of well models in isotropic mediums for 2-phase settings
• Vertical well implementation in isotropic mediums for 2-phase settings

Special considerations when implementing mentioned features

• Wells should be writable to disk.
• It's debatable whether well perforated cells should be stored as a "faceSet" or a "cellSet".
• Well sources for each phase should be returned both in explicit and implicit formulations.

Do any of the mentioned features break working functionality?

There is no existing functionality to begin with.

Immediate improvements and potential enhancements for next cycle

• Support three-phase flow with GOR-based drives

[FoamScience]

• The wells now keep cell-based and face-based versions of perforated regions.
