Title: Dual pump system in which the discharge of a first pump is used to power a second pump

Abstract: A system and method that permits fluids, such as petroleum, to be pumped from two separate zones. A submergible pumping system, including a submergible electric motor driving a submergible pump, is deployed in a wellbore. The submergible pump intake is located in a first zone to intake a fluid. The fluid is discharged through a fluid-powered pump, such as a jet pump. The jet pump is coupled to a fluid intake disposed in a separate zone within the wellbore. The single system can be utilized to pump fluids from two different zones.
