... alternatives. 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 of the SAGD process is performed. The CMG "STARS" ™ thermal simulator was used...

... Abstract The effect of hydrocarbon gas injection on oil production during Steam Assisted Gravity Drainage (SAGD) projects was investigated using numerical simulation. The results indicate that oil production rates as well as total oil production are significantly reduced when gas is injected...

... Abstract Hilda Lake is a steam assisted gravity drainage (SAGD) project. The Mahkeses project is an expansion of the Imperial Oil Resources Limited commercial Cold Lake project based on Cyclic Steam Stimulation (CSS). Both projects are being implemented in the same Clearwater reservoir...

... Abstract Following the 1996 success of two Single Well Steam Assisted Gravity Drainage, (SW-SAGD), wells in the Celtic Field, Saskatchewan, Mobil Oil Canada piloted a Dual Well Steam Assisted Gravity Drainage, (DW-SAGD), well pair in 1997. The well pair was located in the Sparky-General...

... 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. This paper is a continuation of parts 1 and 2 presented at the 48 th and 49 th Annual...
