Gas lift

This section becomes available when you select gas lift (valve) or dual-string gas lift as the well lift method.

For dual-string gas lift, enter the following data:

For valve gas lift, enter the gas-lift gas properties (temperature, gas gravity relative to air, CO2, H2S, and N2 content).

Depending on the selected calculation method (fixed depth or depth list), the remaining required parameters may differ.

If you select the "Fixed depth" calculation method, enter:

gas injection depth;
valve diameter;
discharge coefficient;
gas lift rate or gas-liquid ratio (depending on the selected gas lift rate type).

If you select the "Depth list" calculation method, enter:

casing head pressure;
valve pressure drop;
a set of valve depths;
gas lift rate or gas-liquid ratio (depending on the selected gas lift rate type).
