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 (t) and attenuation time (α), collecting data indicative of density using a density device, and processing the combination of data indicative of t, α and density to determine the concentration of gas-hydrate saturation and porosity of the formations.
