For the WellModel from the simulator to use. Not decided totally,
well_collection might need to be updated during the simualtion due
to the update the target of wells.
Current understanding. Two ways might prevent to return the guide_rate here
1. preventing the well from group control with keyword WGRUPCON
2. the well violating some limits and working under limits. We do not have strategy
to handle this situation yet.
Very hacky way here. The logic of the code is that only
a well is specified under GRUP control, it is under group
control. Which is not the case observed from the result.
From the result, if we specify group control with GCONPROD
and WCONPROD for a well, it looks like the well will be
under group control. TODO: make the logic correct here
instead of using `false` here.
when well is closed due to rate economic limits, based on the auto
shut-in configuration, the well can be STOP or SHUT.
When well is closed due to all the connections are closed, it should be
SHUT.
