SUMMARY
The discussion focuses on calculating the volume of methane using pressure, temperature, and density, specifically under non-ideal gas conditions. The user has identified the need to apply the Z compressibility factor (Z = 0.81) and the ideal gas law, represented as PV = ZnRT, to derive the number of moles (n) of methane. The user has provided specific values for pressure (P = 2195 psia), temperature (T = 580 °R), and the gas constant (R = 10.73 psia). The goal is to find the gas volume to subsequently calculate the formation volume factor (Bg).
