Geomechanical Characteristics of Hydrate-bearing Sands ...
This thesis presents an experimental study on the geomechanical characteristics of lab-synthesized methane hydrate bearing sand. Sand was tested in four different states, namely, base sand (BS), frozen sand (FS), gas-saturated hydrate bearing sand (HS), and water-saturated hydrate bearing sand (WHS)...
