(a) A well drilled into a gas cap for gas recycling purposes is found to be in an isolated fault block. After injecting 50 MMSCF (14.7 psia and 60 oF), the pressure increase from 2500 to 3500 psia. Deviation factors for the gas are 0.90 at 3500 and 0.80 at 2500 psia and the bottom-hole temperature is 160 oF. What is the cubic feet of gas storage space in the fault block?
