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 with the Gas Material Balance equation:

 P_{\bar{P}}= P_{P_{wf}} + q b_{pss} [1]

where

 b_{pss} = \frac{1422 \times 10^3\ T_R}{kh\ J_D}
