Beschreibung
Zusammenfassung:	A method for constructing elastoplastic property correlations in multicomponent particulate systems. The method includes obtaining parameters from geophysic al data of a sediment-hydrate system, where the parameters include s hyd and p c, and where s hyd is a hydrate saturation and p c is 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 (see above formula), and where .alpha. = p c/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.
