Forecast of Distribution and Thickness of Gas Hydrate Stability Zone at the Bottom of the Caspian Sea

The Caspian Sea is a region of active hydrocarbon production, where apart from conventional accumulations, gas hydrates (GH) are known to exist. GH potential future source energy, however, currently they pose danger for development fields. goal this research was determine the area distribution and thickness their stability zone in using numerical modeling define how certain parameters affect calculated thickness. As result research, cartographic schemes were created South Middle Caspian, predicted. For conditions methane formation exist at depths more than 419–454 m, 416–453 m. maximal thicknesses zones can reach 900–956 226–676 Variations seafloor depth, geothermal gradient composition significantly change resulting zone.
