Some of the complexity of oil recovery process, such as SAGD(Steam Assisted Gravity Drainage), can be resolved by carrying out experimental and numerical evaluations together. In this study, numerical simulation...

...ABSTRACT SAGP is a thermal oil recovery process that is similar to Steam-Assisted Gravity Drainage (SAGD) but which involves the addition of a small concentration of a non-condensable gas to the steam.
