Variations in the elastic parameters of a hydrate-bearing rock formation with gas saturation. Model 1 is a pore-filling model, Model 2 is a thermodynamic elastic model, and Model 3 is a particle cementation model. (a) Relationship between and gas saturation; (b) relationship between and gas saturation; (c) relationship between Poisson’s ratio and gas saturation.
