Power Fluid Pump
The surface pump that pressurizes the power fluid and sends it down the well. It is the only part of a jet pump system that moves.
What it does
Delivers the rate and pressure of power fluid that the downhole jet needs. Raising its horsepower raises the power fluid rate and the production the well can lift.
Basics
| Type | Multiplex (positive displacement) pump |
| Power fluid | Refined oil, water, or oil mixed with produced water |
| Driver | Electric motor or engine; some run on gas from the well |
| Can feed | One well or several wells through a manifold |
Common failures
- Wear of plungers and packing from solids left in the power fluid
- Loss of rate when the driver or belts underperform
Troubleshooting
- Symptom
- Power fluid pressure falls at the same pump speed
- Likely cause
- Worn pump plungers or valves, or a leak downstream
- What to check
- Check pump volumetric efficiency, then the wellhead and tubing for leaks
- Symptom
- Pump packing wears fast
- Likely cause
- Solids in the power fluid
- What to check
- Check the conditioning unit and desanders
