Question: The production data for a gas field are given below Piz (psia) G. MMM SCF) 0.393 6553 6468 1.642 6393 3.226 6329 4.260 6246
The production data for a gas field are given below Piz (psia) G. MMM SCF) 0.393 6553 6468 1.642 6393 3.226 6329 4.260 6246 5.504 6136 7.538 6080 8.749 Assuming a volumetric behavior calculate the following. a) Determine the initial gas in place b) What will be the recovery factor at a p'z of 800 psia? c) The field is to be used as a gas storage reservoir into which gas is injected during summer months and produced during the peak demand months of the winter. What is the minimmum piz value that the reservoir needs to be brought back up to if a supply of 50 MMM SCF of gas is required from the abondoumant p'z is 800 psia?
