Q What advantages do jet pumps offer vs competing lift methods
A With no moving parts, they are the most reliable of all artificial lift methods. Also all key flow wetted areas are manufactured in tungsten carbide material to mitigate erosion.
Q Is a workover required to install / retrieve a jet pump
A No, using wireline they are set as shown below (right) across a sliding sleeve, or can be set in a straddle assembly across a side pocket mandrel as shown below (left) or across holes punched in the tubing .
Q How do jet pumps work
A High pressure power fluid, supplied to the pump via the production tubing annulus, mixes and shares its energy with produced fluid within the pump, thus increasing produced fluid pressure.
Q What type of fluid can be used as power fluid
A Usually water or dead crude. If water is used, it can often be supplied from existing water injection surface and subsea infrastructures
Q How much power fluid is required
A Depends on the head requirement. The ratio of power fluid to reservoir fluids typically ranges from 0.5(small head) to 5(large head). Also strongly influenced by the available power fluid pressure; the higher the pressure, the lower the power fluid rate required.
Q What differentiates the PTC jet pumps
A Optimised hydrodynamics, materials and coatings result in improved efficiency and reliability. Our optional integral SSSV provides enhanced well integrity.
