DUAL INJECTION AND LIFTING SYSTEM
Document Type and Number:
WIPO Patent Application WO1999015755
Kind Code:
A8
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, or alternatively, separately lifting the remaining produced water to the ground surface. 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.
