  • Fluid characteristic determination of a multi-component fluid with compressible and incompressible components
    Patent number: 9383242
    Abstract: A method for determining fluid characteristics of a multicomponent fluid is provided. The method includes a step of measuring a first density, ?1, of a multicomponent fluid comprising one or more incompressible components and one or more compressible components at a first density state. The method further includes a step of adjusting the multicomponent fluid from the first density state to a second density state. A second density, ?2, of the multicomponent fluid is then measured at the second density state and one or more fluid characteristics of at least one of the compressible components or the incompressible components are determined.
