FIELD: oil industry.
SUBSTANCE: invention relates to methods of oil deposits development, in particular, to methods of thermal impact on deposit, containing high-viscosity oil. Method of heavy oil deposit development, which involves drilling of flowing and injection wells and pumping methane-containing gas in formation, produced gas is pumped back in the formation after separation, before pumping produced gas in the formation catalytic conversion is performed to produce heated methane-containing gas, containing water vapour, carbon dioxide and hydrogen.
EFFECT: technical result is increasing oil recovery factor, reduced power resources consumption, reduced costs for pumping and losses, associated with excess heat release into atmosphere.
