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.

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.
