Sometimes producing wells produce at nearly constant bottomhole pressure, when it is being reduced by the downhole pump to its minimal value

, specified by the pump location inside the
wellbore.
In this case the liquid rate is starts declining

This does not actually qualifies this production the well operation as Pressure Control and the well is still under Liquid Control conditions and once bottomhole pressure raises above minimal the pump returns to producing the target liquid rate
