A method of extraction of fuels, organic pollutants, and elements from Methane hydrate deposits, shale seams and the soil is described which freezes the zone and heats the center carrying the fuel, chemicals and water in these deposits and seams from where they are found, be it deep in the sea or on land, and carries them into the condensing unit in inert Nitrogen gas. Required drilling on the surface or sea bottom includes a main shaft and with auxiliary narrow drillings widely spaced from the shaft. The extraction zone, which is first cooled to brittle cold using the evaporation of Liquid Nitrogen and fractured with vibrations, is heated to the highest temperature of the hydrocarbon fraction desired to be extracted. The evaporating hydrocarbons are extracted in a Nitrogen gas carrier, a recognized fire suppressant (NFPA Code 2000). To speed the extraction rate, tonal input from two or more sounding units vibrates the seam structure freeing the evaporated hydrocarbons allowing more rapid escape into the shaft. To prevent air loss in aquifers, ice barriers seal the zone periphery. These hydrocarbons are separated into the hydrocarbons fractions, into fuel fractions as heating oil, kerosene, gasoline, ethers, and fuel gas including methane, Argon / Oxygen and rare gas segments, or, if pollutants, into the separate chemicals by boiling point. The thermal gradient of the extraction pipe is implemented by sourcing the Nitrogen from Liquid Nitrogen and bundling those pipes with the extraction pipe condensing its contents by hydrocarbon fractions into vessels and gas drums depending on boiling points of fractions. Water is separated from the gasoline segment and purified first by separation and then by freezing. The extraction of deep deposits layer the extraction zones as well as work neighboring extraction zones covering many acres. Fuel gases can be liquefied or burned in an on-site electric generating plant.

An oil and gas exploitation method for an oil shale through high-temperature convection-heating of the hydrocarbon gas relates to a mineral exploitation method. The high-temperature overheating water steam convection heating is used by the prior art to exploit oil and gas of an oil shale. As the temperature capacitance coefficient of the high temperature overheating water steam is low, heating of a mineral layer is slow, which increases the cost and reduces the efficiency. Some oil shale deposits are in the desert, and much water is needed by the overheating water steam heating, so the deposits cannot be exploited. The invention uses the hydrocarbon gas as the convection heating fluid. The high temperature hydrocarbon gas is injected into the oil shale along a heat injection well, and the heated mineral layer causes pyrogenation of the kerogen to form oil and gas, which is carried by the low-temperature gas or water along a production well to the ground. After the oil and gas is separated from the water, gas will be separated independently to from the oil and gas product, and the hydrocarbon gas will enter a storage tank to be pressurized and heated to the designed pressure and temperature. Then the hydrocarbon gas will be injected into the oil shale mineral layer for circulating exploitation of oil and gas. Thus, the oil and gas exploitation method for an oil shale through high-temperature convection-heating of the hydrocarbon gas is economical and more convenient for application in the industry.
