Abstract
The present invention provides an apparatus and method of producing a stream of hydrocarbons and water from a wellbore and separating the stream into a hydrocarbon-rich stream and a water-rich stream that can be reinjected into the wellbore from which it was produced. The method involves producing a production stream from production tubing in the wellbore to a separator located at least partially above the wellbore, separating the production stream into a water-rich stream and an oil-rich stream, reinjecting the water-rich stream into the wellbore from which it was produced; and maintaining separation of the water-rich stream from the production stream.
