Artificial lift is a technique used to provide energy to the formation fluids in a production well when the pressure of the formation is not high enough for hydrocarbons to flow up the tubing string at an economic rate. Several types of artificial lift can be used to increase the production rate and maximize hydrocarbon recovery. The major artificial lift technologies are beam pumping/sucker rod pumps (rod lift), progressive cavity pumps, hydraulic submersible pumps, electric submersible pumps, and gas lift.
