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.
