Abstract

An apparatus for downhole use in an oil well, the apparatus comprises a first (8) and a second (12) hydrocyclone, the underflow of the first hydrocylclone is connected to the inlet of the second hydrocyclone; an first pump (7) for pumping production fluid into the inlet of the first hydrocyclone; and a second pump (10) for pumping liquid from the overflow of the first hydrocyclone to the surface; the overflow of the second hydrocyclone is connected to the inlet of the first pump, or to the inlet of the second pump,and the underflow outlet of the second hydrocyclone is discharging into the well.
