METHOD OF THERMAL DEVELOPMENT OF GAS HYDRATE FIELDS AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2012 - IPC E21B43/24 

FIELD: oil and gas production.

SUBSTANCE: according to the inventions there performed is a drilling of accumulation crossing the productive formation of at least one productive well with the system of horizontal side sections, formation of thermic field and hydrocarbon withdrawal from the formation. According to the inventions there performed is a drilling of, at least, one pair of wells: intake and productive, horizontal holes of which are parallel and directed towards one another. Supply of hot heat-transfer medium from thermal energy source into heating well and pumping of obtained products of hydrates decomposition - gas and water is done through production well. Hydrates decomposition products are supplied to separator for separation. Note that the source of thermal energy is nuclear reactor that is connected to recirculation discharge pipeline interconnected with the cavity between production string and tubing string. Tubing string is plugged at the bottom part and perforated at the horizon of the productive formation.

EFFECT: increase of mining efficiency due to improvement of solid hydrocarbons heating for the purpose of their melting and evaporation.
