Predictive Maintenance · Gas Lift
Gas-lift instability. Caught before production drops.
An unstable gas-lift well underperforms by 10-25% of potential because the lift gas is wasted on cycling instead of continuous production. Per-well ML detects casing pressure oscillation, valve loading drift, compressor fade, and liquid loading. The combined ROI is deferred production recovery plus compression-fuel reduction.
Four gas-lift signatures.
Signature
Instability / slugging
ML detects
Casing pressure oscillation outside expected envelope
Root cause
Injection rate misaligned with formation, valve depth wrong
Action
Tune injection rate; verify valve depth schedule
Signature
Valve loading
ML detects
Injection-to-production ratio drift >20% over baseline
Root cause
Valve set point drifted, valve seat wear, scale on valve
Action
Pull valve at next scheduled workover; ML attributes to specific valve
Signature
Compressor pressure fade
ML detects
Compressor discharge pressure declining at constant rate
Root cause
Upstream compressor (gathering side) losing efficiency
Action
Cross-reference /predictive-maintenance/compressor signatures
Signature
Liquid loading
ML detects
Production drop with stable casing pressure
Root cause
Velocity below critical (gas not lifting liquid), pressure depletion
Action
Plunger consideration; or stronger gas-lift via deeper valve

Frequently asked
What gas-lift engineers ask.
What gas-lift failures does WorkSync detect?
Instability/slugging (casing pressure oscillation), valve loading (injection-to-production drift >20%), compressor pressure fade, liquid loading.
Why does instability cost so much?
Unstable gas-lift well underperforms 10-25% because lift gas wastes on cycling, not continuous production. 500 BO/d well = 50-125 BO/d lost.
Lead time?
Casing pressure oscillation: real-time. Valve loading: 1-3 weeks. Compressor fade: 1-4 weeks.
Data needed?
Casing pressure, tubing pressure, injection rate, production rate, compressor discharge pressure.
Auto-tune injection?
We flag deviation + optimal injection rate. Operator actions the change. Integration to lift-gas optimization controllers is Phase 2.
ROI?
200-well gas-lift program typically recovers 5-15% deferred production + compression-fuel reduction. Fuel reduction alone often pays for annual license.
