On Steam Based Recovery Process Design
Steam-based thermal recovery process is the most commonly used recovery process for bitumen production from oil sands reservoirs. The most used thermal methods are Steam Flooding (SF), Cyclic Steam Stimulation (CSS), and Steam Assisted Gravity Drainage (SAGD). The choice of method depends on the …

On Stability in Gravity Drainage Oil Sand Recovery Process
The controlling feature of steam-based recovery processes is heat transfer from the steam chamber to the formation – the greater the heat flux, the larger the oil volume heated and the higher the oil drainage rate. Stability phenomena in SAGD occur both at the edge of the chamber and at the liquid …
