Brief
Gas Flowing Material Balance is the advanced engineering technique to determine the Reservoirs GIIP and recovery as well as Well's EUR and JD.
Gas Flowing Material Balance is applied on the Well level given readily available well flowing data: production rate and tubing head pressure.
Math & Physics
Combining the gas pseudo state flow equation and the Gas Material Balance equation:
where
Material balance pseudo-time:
