      initialized to the welspecs phase. This is not wildly random - but the
      injection_phase will not be meaningfull before an update(Phase) call has been
      issued.

      The welspecs_phase is the preferred phase specified when the well is
      defined with the WELSPECS keyword. This member is immutable, and it is only
      used when initializing the well equations for a producer.
