A separator for separating or partially separating oil, water, gas and solids from hydrocarbon production well fluids comprises a vessel and a cyclone contained within the vessel. An inlet passage passes through a wall of the vessel and into the cyclone, the inlet passage having means for causing the flow to rotate within the cyclone. A first outlet passage for an oil rich phase extends from a position within the cyclone and substantially on a central axis of the cyclone; a second outlet passage for a water phase extends from a base of the vessel; and a third outlet passage for the solids extends from a lower end of the cyclone.
