ABSTRACT:
A method for downhole separation of oil and water within a production fluid downhole in an oil well, includes providing a cyclone separator connected to the outlet of a downhole pump or two or more cyclone separators mounted within a housing and connected to the outlet of a downhole pump. One outlet of the separator or housing is connected to a conduit for transporting the lower density stream to the surface and the second outlet of the separator or housing is connected to a conduit for transporting the higher density stream to an underground formation. The pre-separator downhole pump is preferably selected to maintain dissolved gases in solution while production fluids are within the pump and separators and prevent gas breakout from occurring.
