5 The production data for a gas field are given below. Assume volumetric behavior and calculate the following: (a) Determine the initial gas in place. (b) What percentage of the initial gas in place will be recovered at a p/z of 1000? (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 minimum p/z value that the reservoir needs to be brought back up to if a supply of 50 MMM SCF of gas is required and the abandonment p/z is 1000? p/z (psia) Gp (MMM SCF) 6553 0.393 6468 1.642 6393 3.226 6329 4.260 6246 5.504 6136 7.538 6080 8.749
