...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 48th and 49th Annual Technical...

.... The mechanisms are not fully understood. The current numerical study attempts to better understand the SAGD process where gas is either present or co-injected. Numerical simulations were based on comparison with published laboratory experiments. A sensitivity study was carried out to examine the effects of gas...

... is to be economically produced. We shall show later that the realisation of very high oil recoveries is indeed attainable. Examples already exist of recoveries at the level of 50% using SAGD and even higher for miscible solvent flood. The question as to whether these are economic, or the best that can be achieved...

... a heavy oil/oil sand reservoirs with a con- tiguous water sand (water which may lie below or above the oil-bearing zone) is risky due to the possibility of short cir- cuiting the steam chamber.

...1ABSTRACT 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 Petroleum...

... as the number of well pairs is increased. Horizontal well pairs are predicted to have much lower early to midlife SOR's than would an equivalent arrangement of vertical wells using the SAGD process. Simulations indicate significant oil plugging takes place in thinner thief zones. Simulations...

...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...

.... This is a pre-print and is subject to correction. Abstract At the 4@ Annual Technical Meeting, one of us presented a paper that showed that there was a possibility of making the SAGD process more eflcient by adding a small concentraton of a non-conakn~~ble gas slcch as methane to steam, For this to be effective...

... (Combustion Override Split Production Horizontal Well) operates in a similar manner to SAGD (Steam Assisted Gravity Drainage). IL in fact operates as gravity stabilised air injection displacement, so it is likely to be a low rdte process. In all of this work. the emphasis has been on well arrangements using...

... process, COSH, has been conceived to combine the benefical features of gravitv drainage and horizontal production wells.
