Abstract: An improved method for the recovery of hydrocarbons from a hydrocarbon deposit comprising the steps of introducing a diluent gas along a predominantly horizontal injection well drilled at the base of a hydrocarbon deposit; creating an initial communication path with a predominantly horizontal production well spaced laterally apart from the injection well; gradually enriching the diluent gas with a hydrocarbon solvent to produce a hydrocarbon solvent vapor which is saturated at reservoir conditions; continuously circulating the diluent gas and the saturated hydrocarbon solvent vapor through the hydrocarbon deposit; and producing mobilized hydrocarbons from the hydrocarbon deposit.
