Initial Observations
- Confirm depth and placement details
- Check for recent choke or rate adjustments
- Identify any operational changes from prior shifts
Potential Causes
- Gas interference
- Solids accumulation
- Scale deposition
- Flow regime changes in deviated sections
- Power fluid rate inconsistencies
- Surface equipment malfunction
Diagnostic Steps
- Compare measured intake pressure with model predictions
- Inspect separators and filters for carry-over
- Review data for slugging patterns
- Check for nozzle or throat erosion
- Evaluate power fluid pump output logs
Corrective Steps
- Adjust power fluid rate
- Improve separation and filtration
- Replace nozzle or throat if worn
- Conduct scale treatment
- Modify choke settings to stabilize inflow
- Verify seal integrity in the completion
