The first consumer of water jets pump was James Thompson back in 1852. In 1870, J. M. Rankin introduced the theory of jet pump operation, afterward, a number of papers have been published to develop the technology. The work of Gasoline and O’Brien in 1933 is considered to be the standard reference work. It has been based on both theoretical and experimental results. Since that time, developments in the technology have continued to the point that today jet pumps have high operational flexibility.
What is Hydraulic Lift?
As a general description, Hydraulic Lift (Jet Pumps) represents pumping power fluid at high pressure and rate from surface to activate/drive a downhole pump. Power Fluid can be water or oil.
With Jet Pump applications the completion needs to have minimum 3 flowing conduits:
- A conduit for power fluid injection (inside of the tubing in case of standard flow, and in the annular space in case of reverse flow).
- For reservoir fluid flow (below the JP & packer).
- And a conduit for commingled fluid flow to the surface.
Jet Pump working principle:
The jet pump artificial lift system is composed of two principal parts: the surface pumping equipment and the downhole jet pump. In the surface, the reciprocating pump transfers energy to the fluid increases its pressure, drove through surface piping, production tubing (or annular space) until the jet pump, placed on the bottom.
