Simultaneous production and injection can be achieved in a single well bore. Injection into the lower zone provides pressure support for the upper production zone to increase production.

A flow crossover with high strength bypass tubing is used with a pump support. Zone isolation is either with a seal bore packer or a retrievable tubing packer.

The seal bore packer allows zonal isolation during workover, where the tubing retrievable packer does not.
