  • Downhole oil/water separation system with solids separation
    Patent number: 6189613
    Abstract: A downhole oil/water separation apparatus and process which separates solids from total production fluid prior to oil/water separation is disclosed. Production fluid is passed to a downhole solid/liquid cyclone which separates the fluid into a solids enriched stream and an oil/water stream. The oil is then commingled with the solids enriched stream and brought to surface. The water is reinjected downhole. The method effectively removes solids from the disposal fluid and thus avoids injectivity impairment caused by solids plugging.
