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.

Advantages
- Injection to lower zone to boost upper zone reservoir pressure to increase production in a single well bore
- Ability to recycle produced water from the produced zone and recycle into the lower injection zone
- Seal bore packer allows zone isolation with an isolation valve during workover to prevent zone communication where the tubing retrievable packer does not
