... model based on available data of Surmont reservoir using CMG STARS. According to previous simulation studies, the time of co-injection, solubility data, ex-solution rate, injection pressure and amount of NCG co-injected are important mechanisms affecting the simulation of NCG in SAGD. These parameters...
