Abstract
The present invention relates to an apparatus and method for selectively lifting produced fluids, including produced hydrocarbons and a portion of produced water, to a ground surface while injecting the remaining produced water into an injection zone subsurface in a subterranean well. The invention preferably utilizes an electrical submersible progressive cavity pump (ESPCP) in conjunction with an electrical submersible pump (ESP) in order to carry out the dual injection and lifting steps. Further, this apparatus and method make it possible to produce hydrocarbons from oil wells in a manner that poses less risk and disturbance to the environment.
