Power Fluid Tubing
The tubing string that carries pressurized power fluid from surface down to the jet pump.
What it does
Delivers power fluid to the nozzle. In a free installation the pump itself travels inside this string, pumped down and circulated back up.
Basics
| Carries | Power fluid, sometimes with production chemicals |
| Free pump | Pump runs inside this string |
| Heavy oil | Heated power fluid can thin viscous crude |
Common failures
- Tubing leak that sends power fluid straight to the annulus
Troubleshooting
- Symptom
- High power fluid rate with low production
- Likely cause
- Tubing leak bypassing the pump
- What to check
- Pressure test the tubing
