The Viscoplastic Behavior of Natural Hydrate‐Bearing Sandy‐Silts Under Uniaxial Strain Compression (K0 Loading)

Abstract: The in‐situ stress state and geomechanical properties of hydrate‐bearing sediments impact hydrate formation and gas production strategies. We explore the uniaxial strain compression and stress evolution of natural hydrate‐bearing sandy‐silts from Green Canyon Block 955 in the deep‐water Gulf of Mexico. We performed constant rate of strain uniaxial strain experiments, interrupted by periods where we held the axial stress constant, to explore the vertical deformation and the evolution of the ratio of lateral to … Show more

“…12 Later experiments measured similar hydrate saturation (79−93%) across different samples of the sandy-silt biscuits. 14,23,24 Furthermore, later P-Wave velocities of pressure cores showed negligible difference from those taken in 2017 25 (Figure 3). The P-Wave velocities are positively related to methane hydrate saturations.…”
