Stability and Phase Boundaries of Gas Hydrates

The presence of gas hydrates is controlled by several factors, among which, temperature, pressure, ionic strength of the water and gas composition and abundance are key parameters (Sloan 1998). The pressure/temperature conditions required for pure methane hydrate stability are illustrated inFig. 14.3. In this case, methane hydrate is stable at temperatures 

Accurate and precise prediction of the P/T conditions for natural gas hydrate stability is a field of active research, and numerous methods for predicting methane hydrate stability can be found in the literature (summarized in Sloan 1998). Dickens and Quinby-Hunt
