Abstract
A dual submergible pumping system permits pumping of fluids from separate zones within a narrowly confined wellbore without commingling of fluids. The system includes a single deployment tubing from which a first and second submergible pumping system are suspended. The system further includes a fluid transport system having one fluid flow path defined by the hollow interior of the deployment tubing and a second fluid flow path isolated from the first flow path.
