Bgi
A = drainage area in acre h = thickness in ft φ = Porosity (fraction) Sw = Water saturation (fraction) Bgi = Initial gas formation volume factor (ft 3/SCF) RF = Recovery factor (fraction)

Zres Calculation How to calculate Zres ?? Step 1:
Tres is known (available from logs/well test data) Pres is known (available from logs/well test data) Gas Composition is known Step 2: NC
Calculate the apparent molecular weight: Calculate the gas gravity:
γ g =
MW a 28.964
MW a = ∑ xi M i i =1
Zres Calculation Step 3:
Obtain the pseudo critical pressure(P pc) and pseudo critical temperature(Tpc) of the gas from Figure A-2 using gas gravity g ravity.. Correction Correctio n for for CO2, N2 and H2S if necessary. necessary. Step 4:
Calculate the reduced temperature(Tr) temperature(Tr) and reduced pressure(Pr) Tr = Tres/Tpc ; Pr = Pres/Ppc
