Rename the the meaning for shut as whats used in Eclipse.
STOP: Well stopped off above the formation. I.e. allow for flow in the
well.
SHUT: Well completely isolated from the formation. The well is removed
from the well list.
Note that this patch does not introduce any real temperature
dependence but only changes the APIs for the viscosity and for the
density related methods. Note that I also don't like the fact that
this requires so many changes to so many files, but with the current
design of the property classes I cannot see a way to avoid this...
Instead of making well rates zero for wells that are not controlled by
surface volume, we initialize them to a small value with the correct
sign (positive for injectors, negative for producers).
Do not use the well's comp_frac member, only rely on the control's distr
member for initialization. This forced a change to WellsManager's
initialization of the distr member.
This is a minor bugfix to account for the presence of shut wells
(characterised by "ctrls[w]->current < 0"). The existing code would
lead to indexing outside the "ctrls" array in the context of a shut
well.
Bhp is now initialized to bhp target for bhp-controlled wells.
Mobilities and pvt properties are now calculated from
well perforation pressure and injection specifications for
injectors, producers still use cell properties as before.
