  • Systems and methods for determining in-situ gas hydrate saturation
    Patent number: 7983846
    Abstract: Systems and methods for determining in-situ hydrate saturation of hydrate-bearing formations using dielectric properties of gas hydrate amounts are described. In accordance with one aspect, a method for determining gas-hydrate saturation concentration of hydrate-bearing formations includes collecting data using a dielectric propagation tool indicative of propagation time (tpl) and attenuation time (?), collecting data indicative of density using a density device, and processing the combination of data indicative of tpl, ? and density to determine the concentration of gas-hydrate saturation and porosity of the formations.
    Type: Grant

    Date of Patent: July 19, 2011
    Assignee: The Trustees of Columbia University in the City of New York
    Inventors: Yue-feng Sun, David Goldberg
