Description
Five geotechnical researchers test how clay changes the strength of sediments that hold natural gas hydrates. Such clay-rich deposits are candidate gas reserves, and their safety under extraction depends on how they deform and fail. The team ran squeezing shear tests on lab sediments holding hydrates, comparing two clay minerals, illite and montmorillonite, at several clay contents.
The montmorillonite samples hardened more under strain and changed volume more, and both trends grew with clay content. The illite samples were stiffer and failed at higher strength. Failure strength rose with clay content and with the pressure confining the sample, while grip and friction measures each varied in straight-line fashion with clay share. The team folds clay content into the standard Mohr-Coulomb failure rule, giving engineers a way to predict shear strength in clay-rich hydrate reservoirs before mining them.
