Question
1- The following information is available on a volumetric gas reservoir: Initial reservoir
temperature, Ti = 155°F
Initial reservoir pressure, pi = 3500 psia
Specific gravity of gas, yg = 0.65 (air = 1)
Thickness of reservoir, h = 20 ft
Porosity of the reservoir, q= 10%
Initial water saturation, Swi = 25%
After producing 300 MMscf, the reservoir pressure declined to 2500 psia. Estimate
the areal extent of this reservoir.
