Abstract
A method for producing hydrocarbons from a reservoir. The method includes 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.

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.
