Abstract

A method of downhole cyclone separation that is less prone to problems associated with gas breakout. This method include the following steps. Firstly, placing a cyclone separator (12) downhole in an oil well (14) producing a mixed stream of oil, water and gas. The cyclone separator (12) includes a separation chamber (16) wherein liquids of differing densities are separated, at least one mixed liquids inlet (18) through which liquids pass into the separation chamber (16), a first outlet (20) for liquids of a first density range to pass from the separation chamber (16), and a second outlet (22) for liquids of a second density range to pass from the separation chamber (16). Secondly, connecting the first outlet (20) to a recovery conduit (24) extending to surface. Thirdly, connecting the second outlet (22) to a disposal conduit (26) extending to a selected disposal site. The method being characterized by the further step of, fourthly, connecting the at least one mixed liquids inlet (18) to a pump (28) and pumping a mixed stream of oil, water and gas into the separation chamber (16) of the cyclone separator (12). The mixed stream is separated into a recovery stream of oil with a reduced water content which flows out of the first outlet (20) and along the recovery conduit (24) to the surface and a disposal stream of mainly water which flows out of the second outlet (22) and along the disposal conduit (26) to the selected disposal site.
