Strength Estimation for Hydrate‐Bearing Sediments From Direct Shear Tests of Hydrate‐Bearing Sand and Silt

Safe and economic methane gas production, as well as the replacement of methane while sequestering carbon in natural hydrate deposits, requires enhanced geomechanical understanding of the strength and volume responses of hydrate‐bearing sediments during shear. This study employs a custom‐made appara...
