FIELD: oil and gas industry.
SUBSTANCE: recovery method and in-situ performing the hydrocarbon upgrading in the pair of wells, consisting of the injection well and the recovery well within the oil-bearing reservoir, containing the heavy hydrocarbons, includes the following operations: injection of the hot pumped fluid selected amount, including the heavy hydrocarbons fraction, into the injection well to facilitate the recovery of hydrocarbons and in-situ upgrading; the hydrocarbons extraction from the recovery well.
EFFECT: increase of the hydrocarbons extraction with simultaneous upgrading, the impact on the environment reduction, energy costs decrease.
