Abstract

The fluid separation and reinjection system for use in a wellbore extending through a producing zone (22, 190) producing an oil/water mixture and a water reinjection zone comprises a tubing (28, 102, 150, 194) disposed within the wellbore in fluid communication with the producing zone defining an oil flow channel and in fluid communication with the water reinjection zone defining a water reinjection channel. The system further comprises a separator (60) separating the produced oil/water mixture into an oil rich phase and a water rich phase located at least partially above the wellbore and adjacent the wellbore, the separator having an inlet coupled to the oil flow channel and a water outlet coupled to the water reinjection channel. The system also comprises a pump (42, 110, 156) in fluid communication with the separator pressuring the water for reinjection.
