Gas Hydrates are crystalline compounds formed as a result of the combination of certain molecule sizes and water under suitable pressure and temperature conditions. Though they resemble ice, gas hydrates are formed at temperatures well above the freezing point. As a result, large quantities of them exist in sub-sea sediments and permafrost regions, thus possessing many interesting properties such as a preference for large, round molecules and high latent heat.This definitive text, while providing an absorbing overview on gas hydrates, their properties and potential applications (for example, gas separation, storage and transport, heat storage, source of energy), also places special emphasis on flow assurance and how it can be used to prevent gas hydrates problems in oil and gas transport pipelines. It also covers experimental techniques in determining gas hydrate phase boundary in bulk and porous media, thermodynamic modelling and various predictive techniques, and novel techniques that tackle gas hydrate and flow assurance problems. Real-life case studies are included for discussion.
