Surface · Gas Lift
Production Separator
The surface vessel where the lifted fluids are split into gas and liquids.
What it does
Recovers the injected gas plus the formation gas so it can be compressed and sent back down the annulus, closing the loop.
Basics
| Receives | Produced fluids plus injected gas |
| Gas goes to | Compressor, then back to the wells |
| Liquids go to | Treatment and storage |
Common failures
- Slugs from intermittent lift overload the separator
Troubleshooting
- Symptom
- Liquid carryover into the gas line
- Likely cause
- Slug flow from intermittent injection
- What to check
- Smooth injection cycles or size the vessel for slugs
