ABSTRACT:
A downhole oil and water separator for an oil well includes a water-selective membrane disposed in a production flowpath of the well. The water-selective membrane is operable to selectively pass water from the production flowpath to a disposal zone to increase the concentration of oil in the production flowpath at the surface.
