Gas Lift

Continuous gaslift in upstream oil production: well inflow and outflow behaviour, gaslift principle and gradients, valves and unloading, well testing, lift gas measurement and control, monitoring, troubleshooting and optimisation. Intermittent gaslift, ESP, beam pump and PCP are out of scope.

आप क्या सीखेंगे

  • Explain how injected lift gas lowers bottom hole pressure and increases drawdown
  • Calculate static gradient, productivity index and gaslift valve setting depth
  • Distinguish IPO, PPO, orifice and dummy valves and state where each is used
  • Execute and validate a well test on a gaslifted well to procedure
  • Interpret CHP, THP and lift gas rate trends to identify an under-performing well
  • Unload a gaslifted well in controlled steps without damaging the valves
  • Diagnose common gaslift faults and recommend an assigned, actionable remedy
  • Model and optimise lift gas allocation at well and field level
