FIELD: oil and gas industry.
SUBSTANCE: viscous oil or bitumen is extracted from the formation by means of pumping to it of gas and heat carrier heated with reagents obtained from hydrocarbons, and heating. The above heat carrier includes water saturated with carbon dioxide, obtained by mixing the water heated owing to the heat radiated at exothermic synthesis of carbon-containing products from the reagents produced by conversion of hydrocarbons and water saturated with carbon dioxide and taken out of the flow formed during the above synthesis by means of condensation or sorption. Invention has been developed in dependent claims.
EFFECT: reducing the heat carrier flow rate and reducing the costs for its pumping and losses.
