Sucker Rod Lift
Reciprocating, beam, or sucker rod lift is the oldest and most common artificial lift method in onshore US oil production. This is due to both economic factors, such as the ability to create low bottom hole pressures for more inflow and lower operating cost, and to human factors, such as flexibility and familiarity for operations and optimization.
Plunger lift is the primary lift type for de-liquefying gas wells. It is a great fit for lower producing gas wells because of relatively low capital investment, maintenance costs, and energy requirements, compared to other artificial lift methods. Plunger lift is highly energy efficient because it uses the well’s reservoir energy as well as energy from gas pressure in the annulus.
Progressive Cavity Pump (PCP)
Progressive cavity pumps are typically used in heavy oil, dewatering and high GOR applications at depths less than 7,000 ft. PCPs are typically used in applications where the economics of production demand efficiency, reliability and low life cycle costs from artificial lift equipment. Benefits to using a PCP include their low cost, the ability to deal with solids / fines, high efficiencies, and low downtime.
Gas lift uses an external source of high-pressure gas for supplementing formation gas to lift the well fluids. Gas lift is particularly applicable for lifting fluids in wells that have a significant amount of gas produced with crude oil. Gas compressors are nearly always installed to gather the produced gas and, with only minor changes, can be designed to supply the high injection-gas pressure for the gas lift systems.
The electrical submersible pump (ESP) is an efficient and reliable artificial-lift method for lifting moderate to high volumes of fluids from wellbores. These volumes range from a low of 150 B/D to as much as 150,000 B/D. Variable-speed controllers can extend this range significantly, both on the high and low side.
