WebGas hydrates exist in a stable state at very high pressures and relatively low ambient temperatures. Huge deposits of natural gas hydrates are located underneath the oceans and in permafrost regions. Gas hydrates may consist of different types of gas molecules and be sustainably stored for a long time under different equilibrium conditions. WebThe phase saturation derived by the mass balance was 72% of hydrate and 28% of water. After flushing with distilled water, the residual gas was negligible in this experiment. The pore pressure, the axial confining pressure, and the lateral confining pressure were 4.1 MPa, 6.1 MPa, and 5.1 MPa, respectively.
