Undersaturated Oil Reservoir with initial temperature close to pseudo-critical temperature and as consequences 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.
