Abstract: A method includes placing an apparatus in a subsea wellbore (102), and hydraulically connecting the apparatus with an external hydraulic fluid source (107). The apparatus of this method includes a pump (103), a motor (105), a pressure intensifier (109), and a hydraulic fluid port (110). The motor (105) is configured to drive the pump (103). The pressure intensifier (109) is configured to maintain pressure of the hydraulic fluid in the motor at a predetermined level. The hydraulic fluid port (110) is configured to provide hydraulic fluid to the pressure intensifier (109) by mating with the external hydraulic fluid source (107) when the apparatus is in a hydrocarbon producing wellbore. The apparatus is dimensioned for lowering and retrieving through the string of production tubing (112).

Abstract: An apparatus may include a production riser (1), an eductor (2), a motive fluid line (3), a suction line (4), and a mixed fluid line (5). The production riser may extend into a wellbore and be configured to convey production fluid from the wellbore to a wellhead (7). The eductor (2) may be configured to mix a slip stream (9) of the production fluid (6) with high-pressure motive fluid (12), providing a mixed fluid (9). The motive fluid line may extend into the wellbore from a compressor to the eductor and be configured to provide the high-pressure motive fluid to the eductor. The suction line may be configured to provide the slip stream from the production riser to the eductor. The mixed fluid line may be configured to convey the mixed fluid from the eductor to the production riser. A method and system may employ such an apparatus.
