A method of reducing water in oil wells. Firstly, place a cyclone separator (11) downhole in a producing oil well. The cyclone separator includes a separation chamber (15) wherein liquids of differing densities are separated, a mixed liquids inlet (17) through which liquids pass into the separation chamber (15), a first outlet (19) for liquids of a first density to pass from the separation chamber (15), and a second outlet (21) for liquids of a second density to pass from the separation chamber (15). Secondly, connect the first outlet (19) to a recovery conduit (27) extending to surface whereby a stream of mainly oil is separated in the separation chamber (15) from the oil/water stream flowing through the mixed liquids inlet (17). The stream of mainly oil flowing out the first outlet (19) and along the recovery conduit (27) to surface. Thirdly, connect the second outlet (21) to a disposal conduit (33) extending to a selected disposal site whereby a stream of mainly water is separated in the separation chamber (15) from the the oil/water stream passing through the mixed liquids inlet (17). The stream of mainly water flowing out the second outlet (21) and along the disposal conduit (33) to a selected disposal site. |
