  • Patent number: 5363696
    Abstract: An improved method and arrangement for calculating the fluid phase fractions of gas, oil, and water and oil-water emulsion in a fluid steam flowing from an oil well which includes separating out the majority of gas from the well stream and repeatedly trapping a sample of the primarily resultant liquid well stream in a vertically disposed sampling chamber. The well stream sample is held therein to permit separation of the phase fractions to the extent possible within a reasonable time. A number of measurements of the well stream sample are taken. In addition, a number of measurements are taken of the capacitance at a plurality of discrete vertically spaced locations within the sampling chamber. These capacitance measurements relate directly to the varying permitivity of the phase fractions of gas, oil, and water and the oil-water emulsion of the sample. The measurements are processed by a data processor to provide precise information on such phase fractions and emulsion interfaces.
