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.

Abstract: A method and system for dissociating methane hydrate deposits in-situ is provided wherein an oxidizer fluid and a supply of fuel, both at a pressure higher than that of the methane hydrate deposit, are supplied and delivered to the methane hydrate deposit. The fuel is combusted downhole by reacting it with the oxidizer fluid to provide combustion products. The combustion products are placed in contact with a diluent fluid to produce a heated product fluid. The heated product fluid is injected into the methane hydrate deposit whereby methane is dissociated from the methane hydrate and made available for extraction. In addition, carbon dioxide may be made available to promote the formation of carbon dioxide hydrates from the liberated methane hydrate water.

Abstract: This invention which combines an oxygen storage system with a catalytic converter to enhance the conversion of common pollutants found in the exhaust gas stream of an internal combustion engine. The oxygen storage element is placed upstream of the catalytic converter and is designed to extract excess oxygen from the exhaust gas stream and release the extracted oxygen when the exhaust gas stream is oxygen deficient. Controlling the oxygen level in this manner allows for effectiveness of the converter to be increased.
