Abstract:
1. A method of detecting hydrates in a multiphase fluid, comprising: applying energy waves at a plurality of frequencies to the multiphase fluid; determining a first most resonant frequency within a first resonant frequency range for a first resonant circuit coupled to the multiphase fluid to determine a first resonant frequency; measuring a parameter of said multiphase fluid dependent upon frequency at said first most resonant frequency when said first resonant circuit is coupled to the multiphase fluid; determining a second most resonant frequency within a second resonant frequency range for a second resonant circuit coupled to the multiphase fluid; measuring said parameter of said multiphase fluid at said second most resonant frequency when said second resonant circuit is coupled to the multiphase fluid; and determining a presence of hydrates in said multiphase fluid, hydrates and water in said multiphase fluid, water in said multiphase fluid, and no hydrates and no water in said multiphase fluid based on said parameter, said first most resonant frequency, and said second most resonant frequency, wherein measurements of said parameter of said multiphase fluid, said first most resonant frequency of said multiphase fluid, and said second most resonant frequency of said multiphase fluid are interrelated, wherein said first most resonant frequency range is selected from a range corresponding to said multiphase fluid being complex dielectric non-dispersive, and wherein said second most resonant frequency range is selected from a range corresponding to said multiphase fluid being complex dielectric dispersive.
