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

Figure 4

Micro-distribution of gas hydrate during hydrate formation process under methane flux conditions. (a) Hydrate saturation =0%, (b) Hydrate saturation =22.13%, (c) Hydrate saturation =47.33%, (d) Hydrate saturation =59.87%. The yellow is methane hydrate. The blue is NaCl solution. The light gray is sands. The black is methane gas.
