DUAL PRODUCTION AND INJECTION ESP UNIT

Application
1. Injection wells with oil-saturated formations;
2. Production wells with injection potential.
Downhole equipment
Short description
The upper packer protects the production casing from the injection fluid pressure. The lower packer separates the productive and the injected formations. The ESP unit withdraws the fluid from the productive formation through a tubing string of smaller diameter. The agent is injected into the injected formation from the wellhead through the annulus between the tubing strings of larger and smaller diameters.
