1. A method for producing hydrocarbons from a reservoir, comprising:

  • positioning a burner having a combustion chamber in a first well;

    supplying a fuel, an oxidant, and one of water or steam from the surface to the burner in the first well;

    supplying a viscosity-reducing gas from the surface to the reservoir in a conduit separate from the fuel;

    igniting the fuel and the oxidant in the combustion chamber to generate heat and steam in the burner;

    injecting the viscosity-reducing gas and steam into the reservoir to reduce the viscosity of and heat hydrocarbons within the reservoir; and

    recovering hydrocarbons from the reservoir.
