Patent ID: 7472022

Claim:
A method for managing a drilling operation in a multicomponent particulate system, comprising: obtaining a plurality of geophysical and petrophysical data associated with the multicomponent particulate system, wherein the plurality of geophysical and petrophysical data comprises: geophysical and petrophysical properties of a first type of particle in the multicomponent particulate system, acoustic velocities measured in the multicomponent particulate system, and effective confining pressure of the multicomponent particulate system; calculating at least one property corresponding to the plurality of geophysical and petrophysical data; obtaining at least one measurement of an elastoplastic property of the multicomponent particulate system; calculating at least one elastoplastic property of the multicomponent particulate system using the at least one measurement of the elastoplastic property of the multicomponent particulate system; constructing at least one correlation between the at least one elastoplastic property and the at least one property corresponding to the plurality of geophysical and petrophysical data; estimating at least one elastoplastic property of sediments in a formation of interest using the at least one correlation; evaluating mechanical integrity of the formation of interest using the at least one elastoplastic property of sediments; and adjusting the drilling operation based the evaluation.
