Solvent-steam coinjection has been proposed as an alternative to SAGD. Detailed oil recovery mechanisms of coinjection are little known due to complex interaction of phase behavior, and fluid and energy flow. This research conducts a detailed mechanistic study of phase behavior and its contribution to oil displacement efficiency and drainage rate near the chamber edge. Importance of properly considering both phase behavior and flow to design an optimized coinjection process is demonstrated. We propose a systematic procedure for optimum selection of solvent and its coinjection strategy. Results show that a proper design can significantly improve the oil production rate compared to steam-only injection. We also demonstrate how enhanced displacement efficiency can be achieved during a coinjection process.
