Power Fluid Conditioning
A vessel at the wellsite that separates the returning mixture into gas, oil and water, plus cyclone desanders that clean the fluid before it goes back to the pump.
What it does
Recovers part of the returning fluid as clean power fluid for reinjection and sends the rest, the well's production, to the flowline.
Basics
| Main parts | Separator vessel and cyclone desanders |
| Separates | Gas, oil and water |
| Layout | Single well skid or a central battery for many wells |
| Power fluid choice | Oil or water, set by valves on the vessel outlets |
Common failures
- Desanders plugged or worn, solids reach the surface pump
- Poor separation that leaves gas in the power fluid
Troubleshooting
- Symptom
- Sand found at the surface pump
- Likely cause
- Desander not working
- What to check
- Check pressure drop across the desander and its underflow
