In AGL the true reservoir Gas production rate is calculated as the difference between total measured produced gas rate q^{\uparrow}_{GT} and Gas lift rate q^{\downarrow}_{GL} which has been injected into annulus to support the fluid lift in the tubing:
| (1) | q^{\uparrow}_{G} = q^{\uparrow}_{GT} - q^{\downarrow}_{GL} |
