Gas Lift Performance Curve & Friction Turnover
Gas lift aerates the fluid column inside production tubing, lightening its hydrostatic head and lowering flowing bottomhole pressure ($P_{wf}$). By Vogel/Darcy inflow performance ($q = PI \cdot [P_{res} - P_{wf}]$), lower $P_{wf}$ increases drawdown and accelerates reservoir liquid inflow.
The Gas Lift Turnover Peak
As gas injection rate continues to increase, high multiphase flow velocities exponentially drive up tubing frictional shear resistance. Eventually, the increase in friction pressure drop outweighs the decrease in hydrostatic density head. Beyond this optimum injection rate, adding more lift gas increases bottomhole pressure and reduces oil production.
