Dual ESP Production

The Dual ESP system deploys two electrical submersible pumps (ESPs) at different depths in a wellbore. Each zone is isolated so that the operator can monitor and control production independently. The system includes all packers, Y-tool or other splitting equipment, and pumping, downhole power, motor, and auxiliary components. The Dual ESP system is available in two configurations:

• The separate-zone configuration places one ESP deeper in the well at one production zone and the other ESP higher in the well at a second production zone. An isolation packer between the ESPs enables full control and monitoring of each zone.
• The same-zone configuration places both ESPs in a single zone, but the intake for the bottom ESP is mounted on production tubing up to 16 ft (5 m) lower in the wellbore, enabling it to reach a lower production zone. An isolation packer is set around the production tubing extension to ensure zonal isolation.

Injecting While Producing

The injecting-while-producing system uses one downhole pump to force fluid into one formation and an ESP to produce fluid from a second zone. This single-bore water-flood solution maintains downhole pressure to reduce cycling and recover more oil in struggling wells. The injecting-while-producing system can inject from an upper zone and produce from the lower with the aid of isolation packers, or it can inject in the bottom zone and produce from a zone higher in the well.
