Patent abstract
A method of dissociating methane hydrate deposits in-situ is provided in which a supply of oxygen, carbon dioxide, and fuel are provided, the oxygen and the carbon dioxide are mixed to form an oxidizer fluid, and the fuel is combusted downhole by reacting it with the oxidizer fluid to provide hot combustion products. The combustion products are placed in contact with a diluent fluid to produce a cooled product fluid at a temperature higher than the prevailing methane hydrate decomposition temperature. The cooled product fluid is injected into the methane hydrate deposit decomposing the hydrate and releasing natural gas.
