A rock physics model for hydrates bearing sediments of near surface

Gas hydrates presented as form of segregated bodies have been observed on shallow subsurface sediments. However, most gas hydrate physics models describe that hydrates occur in pore space in deep subsurface sediment. A new model considers gas hydrate as segregated bodies to derive elastic properties of hydrates bearing sediments and gas hydrate saturation. The predicted elastic properties based on the model are coincided with measurements of well logs in site 1327 of Integrated Ocean Drilling Program (IODP). The results show the model can be used to estimate gas hydrate saturation from seismic data of near surface
