Abstract:
A Vertical Annular Separation and Pumping System (VASPS) utilizing a outer annulus liquid discharge arrangement to replace a standard pump shroud associated with an electrical submersible pump. The outer annulus liquid discharge arrangement directs produced wellbore liquids around the electrical submersible pump motor to provide a cooling medium to prevent overheating and premature failure of the electrical submersible pump.
