- Production Tubing (Comingled Production)
Multiple reservoirs can be produced independently in the same well bore. In cases where the upper zone and the lower zone require an ESP, a dual zone completion can be used with a single production tubing string by comingling the discharge of each ESP.
When the distance between zones is restricted, a pod system
with seal bore packer can be used.
This also allows zones to be isolated with an isolation valve to prevent communication between zones during a workover.

Advantages
- Injection to lower zone to boost upper zone reservoir pressure to increase production in a single well bore
- Ability to recycle produced water from the produced zone and recycle into the lower injection zone
- Seal bore packer allows zone isolation with an isolation valve during workover to prevent zone communication where the tubing retrievable packer does not
