Abstract

Gas hydrates are ice like crystals structure of water molecules and hydrocarbons formed under the favorable conditions. In gas hydrates crystals mainly methane gas is trapped within a framework of cages of water. Gas hydrates are mainly found in shallow sediments of outer continental margins and permafrost regions. Oceanic occurrences of gas hydrates are inferred mainly on the basis of appearance of bottom simulating reflector (BSR) in the seismic section, that coincides with the base of gas hydrate stability field (low temperature and high pressure).
