Estimating in situ mechanical properties of sediments containing gas hydrates

hyd chyd c cA method for constructing elastoplastic property correlations in multicomponent particulate systems. The method includes obtaining parameters from geophysical data of a sediment-hydrate system, where the parameters include sand p, and where sis a hydrate saturation and pis a confining pressure. The method further includes determining a Young's modulus (E) of the sediment-hydrate system using the parameters and a correlation, where the correlation is and where α=p/c and c is a scaling variable with dimensions of pressure. The method further includes adjusting a field operation based on the Young's modulus of the sediment-hydrate system.
