Choke Manifold
A group of valves and chokes, with at least two choke paths so one can be isolated and serviced while flow runs through the other.
What it does
Controls the well rate and takes the pressure drop ahead of the surface test equipment, with pressure sensors to follow the test.
Basics
| Chokes | At least two paths |
| Also has | Valves and pressure sensors |
| Lets you | Service one choke while flowing through the other |
Common failures
- Choke worn by sand, so the rate drifts
Troubleshooting
- Symptom
- Rate rises at the same choke setting
- Likely cause
- Worn choke
- What to check
- Switch to the other path and inspect the choke
