  • Fluid compositional analysis by combined gas chromatographic and direct flash methods
    Patent number: 8522600
    Abstract: A method and apparatus for providing compositional analysis of hydrocarbon fluids from well samples up to a C30+ fraction. The method includes the steps of heating a sample to a temperature of about 220° F., and collecting the liquid and gaseous fractions therefrom. Both the liquid and gaseous fractions are analyzed by gas chromatography. Additionally, the volume of the gas, and the volume, molecular weight and mass of the liquid are determined. The results are then analyzed to provide a total composition of the hydrocarbon fluids.
    Type: Grant
