Coiled Tubing Cleanout
Using coiled tubing to remove fill such as sand, scale and debris from the well.
What it does
Coiled tubing works on live wells and can pump fluid at any time, going in or coming out, so fill is washed out without pulling the completion or killing the well. It can also deliver nitrogen to lift the well afterward.
Basics
| Removes | Sand, scale, organic material, debris |
| Advantage | No need to kill the well or pull the completion |
| After | Nitrogen lift to kick off the well |
Common failures
- Fill that builds up again and restricts production
Troubleshooting
- Symptom
- Production restricted by fill again
- Likely cause
- Sand not carried to surface by the produced fluid
- What to check
- Repeat the cleanout and review the sand control
