In heavy and extra-heavy oil production, steam stimulation is one of the most commonly used approaches for enhancing the recovery process. Thermal energy of injected steam reduces the viscosity of oil to improve its mobility and facilitate the production process. Conventionally, steam stimulation can be performed by using various technologies, such as Steam-assisted gravity drainage (SAGD), Cyclic steam stimulation, and Steam flood....
