| Abstract: | The bubble point pressures, saturated molar liquid volumes, and densities of a shale oil from the Green River formation in Utah, and a distillation fraction of the oil were experimentally determined as a function of temperature and methane mole fraction. These properties were measured in a static VLE apparatus capable of measuring pressures to 34,500 kPa and temperatures to 450 K. The phase change at the bubble point for the mixtures of oil and methane was determined using the statistical method of splines. The densities for the crude shale oil have been extrapolated to 288.7K (60 °F) using a standard API correlation. |
