FIELD: oil production.
SUBSTANCE: method for developing a high-viscosity oil or bitumen deposit includes building two horizontal wells located one above the other, injecting a solvent into an injection well, and withdrawing the fluid from a production well. The solvent are heated hydrocarbon fractions with a boiling point of less than 210°C under pressure in the form of a gas-liquid mixture with temperatures up to 410°C.
EFFECT: increased diffusion of the solvent into the oil.
