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.
