Gas hydrates are also known as methane hydrates and are cage-structured lattices of water molecules which contains methane, the foremost component of natural gas. Gas hydrates are crystalline, naturally occurring, ice-like substances which is poised of gas particles bonded in a cage-like arrangement. Gas hydrates are a rigorous arrangement of natural gas but are less concerted as compared to liquefied natural gas. Gas hydrates occur in beneath of the sediment outer continental margins in foremost regions of Siberia and Alaska. Gas hydrates occur in a modes of occurrence and varied range of geologic settings. These regions include host lithology, gas hydrate in abundance, and distribution inside the burial depth, sediment matrix, water depth, and several others. The key regulatory factor on where gas hydrate forms is availability of methane and lithology.
