Abstract:
A variation of expanding solvent steam assisted gravity drainage (ES-SAGD) production of heavy oil wherein steam and hydrocarbon solvent are co-injected into a heavy oil reservoir and water, hydrocarbon solvent and heavy oil are produced by gravity drainage until the steam chamber is well developed or until oil recovery reaches about 20-30% of oil in place. At that time, the wells are switched to a lateral sweep using non-condensible gas (NSG) and steam co-injection, where more hydrocarbon solvent is recovered than is recovered with ES-SAGD used alone and where the cumulative steam to oil ratio is reduced over using -ES-SAGD alone.

Claim (Index 3):
The method of  claim 1 , wherein the hydrocarbon solvent is selected from C5-C9 hydrocarbons, C5-C10 hydrocarbons, C5-C14 hydrocarbons, pentane, hexane, heptane, octane, nonane, decane, undecane, dodecane, tridecane, tetradecane, linear and cyclic paraffins, diluent, kerosene, Stoddard solvent, light and heavy naphtha, and mixtures thereof.
