Fig. 1. Production path of the Volatile Oil Reservoir on the Phase Equilibrium Diagram.
The downward solid black arrow shows a reservoir pressure depletion path.
The downward grey dash arrow shows a wellbore lift pressure drop path.
Undersaturated Oil Reservoir with initial temperature slightly lower the pseudo-critical temperature and the Vapour Liquid Envelope having quality lines tighter spaced at reservoir conditions while separator conditions lying on relatively low quality lines.
A small reduction of pressure below the bubble point vaporizes a significant fraction of the oil.
