Benefits of Jet Pumps - Compared to Electric Submersible Pumps (ESP)

Lower Lifetime Costs

Capital Costs

A jet pump system can be installed at greatly reduced costs compared to ESPs, even with high horsepower systems. A jet pump is small in size and easily handled without any handling equipment and fits readily with any completion profiles and fittings.

The power fluid injection units can be operated by natural gas, diesel or electric powered drivers.

Operating Costs
Lower power usage costs are achieved from the surface unit due to increase in jet pump efficiency  compared to costly interventions to change out conventional ESP completion.

Operating Efficiency

Jet pumps have the best overall total process efficiency, in Horse Power (HP) per barrel produced. Achieved through a combination of the Jet pump’s design increasing critical flow areas to increase efficiency dramatically and the 90% efficient Hydra-Cell power fluid pump.

Down Hole Equipment

Jet pumps have no moving parts in the pump resulting in a long service life, no run dry issues. Simple repair procedures is all that is needed to run and retrieve pump downhole. No cable or additional motors, seals, etc. needed. 

Optimise Production

Reservoir Access

Jet pump’s excellent design allows for full bore access to the reservoir. There is no limitations to access and no workover is required for any remedial work. No run dry issues.

Number of Wells

From single to multiple wells operating from one single surface hydraulic package greatly reduces lift cost with jet pumps.

Well Intervention

Jet pumps do not need a workover or pulling rig. Jet pumps can be easily circulated to the surface without pulling the tubing or it can be retrieved by wireline. This ensures easy maintenance and a longer service life; no change out of total completion needed.

Flexible optimisation of production by simple changes to injection power fluid flow and pressure, mixing tube and nozzle combinations. Especially with changing well conditions.

Designed for Flexibility and Reliability

Well Inclination

Jet pumps are excellently suited to vertical and deviated completion. No need for long radius wellbore bends to get through. Poor drilling issues, such as “dog-leg” or “crooked” drilling, are easily overcome.

Depth Limit

No restrictions with jet pumps with a practical depth to 20,000 ft. This is neither limited by motor horsepower or temperature for ESP.

Tubing and Casing Range

Great flexibility is available and no limitations with the jet pumps range of tubing sizes from 2³/₈” to 4½”.

Sand and Solids Handling Ability
ESP is poor for sand and solids handling as it requires <100 parts per million (ppm) solids. Sands at this concentration is normal wear and tear for an ESP. Not recommended for greater than 100 ppm, due to friction and wear on ESP equipment. Excellent reliability is assured with jet pumps due to increased flow areas, robust parts and special metallurgy and coatings.
