Paper presented at the Annual Technical Meeting, June 13–17, 1999
Paper Number: PETSOC-99-23
...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...
