Methane Flux Effect on Hydrate Formation and Its Acoustic Responses in Natural Sands

Figure 11

Hydrate distribution with changes in shear modulus and shear wave velocity. (a) Pore scale distribution of gas hydrates in sediments by X-CT (modified from [19]), (b) Variation in shear modulus with hydrate saturation in different methane flux, (c) Variation in S- wave velocities with hydrate saturation and analysis of the value of BGTL theory (Data for Figure 11 are in Table S10 in the Supplementary Materials).
