... encompasses oil with API gravity ranging from 10.6-63 along with solution gas-oil ratios of 5-4,631 SCF/STB resulting in saturation pressures ranging 60-10,326 psia at temperatures over the range 50–332 °F. The PVT reports provide a measure of isothermal compressibility; therefore, heat capacity ratio must...

Their correlations were based on typical black-oil model parameters; among them solution gas-oil ratio, mole weight and API gravity of the stock tank oil. These parameters change with liquid composition. This paper...
