Problem 1: The following production data are available from a gas reservoir produced under volumetric condition. p (psia) Gp(MMMSCF) 5000 300 4000 520 The initial reservoir temperature is 237 °F and the reservoir gas critical pressure and temperature are 666 psia and 380 °R, respectively. A) What will be the cumulative gas production at 3000 psia? B) What fraction of the initial reservoir gas will be produced at 3000 psia? C) What is the initial reservoir pressure?
