Question 2: A high-pressure gas reservoir is being evaluated for its production potential. The initial pressure in the reservoir is measured at 4000 psia. The reservoir rock has a porosity of 18%, and 22% of the pore space is occupied by immobile water. The reservoir's gas formation volume factor (Bg) is 0.0035 cu ft/SCF at initial conditions and increases to 0.018 cu ft/SCF at the expected abandonment pressure of 800 psia. a) Determine the volume of gas-initially-in-place (GIIP) per cubic foot of reservoir. b) Calculate the initial gas reserve in standard cubic feet on a unit basis. c) Why is the abandonment pressure important in determining initial gas reserve? d) Given a 500-acre section of the reservoir with an average thickness of 40 feet, estimate the total recoverable gas reserves for this portion of the field. e) Calculate the recovery factor for the gas reservoir.
