... configurations and its impact on steam-based gravity drainage processes is the main topic of this paper. Literature Review Butler5, in the original SAGD patent, disclosed the use of two parallel horizontal wells one atop the other where the top well injects steam into the formation and the lower well produces...

Inappropriate selection of parameters for the WAG process can lead to unstable pressure distribution, early gas breakthrough, and low ultimate oil recovery. Previous studies for achieving the optimum WAG performance are mostly limited...

The methodology explored in this paper uses empirical statistical analysis as well as common waterflood surveillance techniques and analytical methods to develop a mental model of fluid flow...

... of facility, operation, and supply issues. During these shut-in periods, the gravity drainage of cooling bitumen and steam condensate continuously raises the liquid level over the production well. Therefore, the producer downhole temperature keeps decreasing. This situation makes the restart more difficult...

... technology can produce bitumen more efficiently and economically when compared to conventional SAGD. Introduction Axe Lake Discovery is located in northwestern Saskatchewan, about 90 km northeast of Fort McMurray. The bitumen reservoirs are buried about 200m below the surface. The bitumen is quite heavy...

In this Figure, the Young s Modulus - calculated based on rock mechanics algorithms - was calibrated to get a better match with values measured in laboratory tests. With these logs the important variations...

... Gravity Drainage (SAGD). Butler (1) first proposed this method in the late 1970s and it was field tested in AOSTRA's Underground Test Facility (UTF) in the 1980s. The initial phase of UTF testing produced successful field results (2, 3) . Following Phase A, Phase B was started, implementing the use...
