GasPVT
GasPVT takes the mole fraction analysis of a
hydrocarbon gas and generates tables containing
values for physical gas properties commonly
used in the Petroleum industry. The properties
include: z-factor, P/z pressure, gas FVF, gas
viscosity, gas density, gas gradient, and gas
pseudo-pressure.
