Upper Zone Injection / Lower Zone ESP (Seal Bore Packer)
System 18: Dual Zone - Single ESP -Concentric Tubing Strings
Simultaneous production and injection can be achieved in a single well bore. Injection into the upper zone provides pressure support for the lower production zone to increase production.
Produced water from the lower zone can be recycled and injected back into the well. 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.
