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. In this case an ESP packer is used to separate zones.
Compared to the seal bore packer, this configuration has no means of zonal isolation during workover, and requires sufficient distance between zones for the ESP packer and ESP.
