<p>An embodiment of a method for recovering viscous hydrocarbons from a reservoir in a subterranean formation, the method including (a)continuously injecting steam into the formation, (b) injecting a first amount of a solvent into the formation for a first period of time during (a), and (c) stopping the injection of the solvent during (a) and after (b). In addition, the method includes (d) determining the effectiveness of the solvent injected during (b), and (e) injecting a second amount of the solvent into the formation during a second period of time during (a). The second amount is chosen based on the determination in (d). Further, the method includes (f) reducing a viscosity of the hydrocarbons within the reservoir with the solvent during (b) and (e).</p> |
