... Abstract Recent technical advances in the understanding ofin situ combustion have made it worthwhile to consider this process as a serious means of recovering heavy oil. However, it mustfirst prove itself to be economically viable, particularly in comparison with steam-based recovery processes...

... injection technique based on these tests seems questionable. Introduction Success of oil recovery by air injection greatly depends on knowledge of reaction mechanism between oxygen and oil in porous media. Oil oxidation during in-situ combustion involves numerous competing reactions occurring through...

... Abstract The relevance of various oxidation reactions to the modelling of in-situ combustion in heavy oils was studied in three sets of experiments. The first set of tests involved temperature-programmed thermal gravimetric scans of three heavy oils and their SARA fractions. A comparison...

... Abstract In heavy oil production by in-situ combustion, information on the relative importance a/the combustion and steamfronts is very useful in the development of good production strategies. To obtain this information/or two reservoirs, one containing heavy oil and the other a bitumen...

... Abstract In situ combustion is a thermal recovery method with a high potential forrecovering the vast hydrocarbon reserves located in the Athabasca Oil Sands. Inorder to understand and optimize the combustion process, fireflooding has beenthe focus of laboratory investigations by the In Situ...

... Abstract An important step in the numerical simulation of in-situ combustion for enhanced oil recovery is the selection of the pseudocomponents used to represent the oil. Frequently the oil is separated according 10 distillation cuts. In addition, a hydrocarbon pseudocomponent called "coke...

... Abstract Saskatchewan's proven reserve of heavy oil is estimated at 4 billion m 3 . About 20% of this reserve is recoverable by enhanced recovery processes. Thermal processes such as steam flooding and in situ combustion are the techniques most frequently used for these relatively cold...

... Abstract In situ combustion, and its modified forms, continue to be important oil recovery processes. The applicability of in situ combustion to a wide range of reservoirs, and the recent advances, show that this process has unique advantages (and disadvantages). Laboratory studies of in situ...

... itu combustion andimmiscible carbon dioxide flooding will help produce a sizable fraction ofheavy oil in Saskatchewan. However, a great deal of laboratory research andfield-testing will be needed in order to double the present heavy oilproduction over the next ten years, which was the goal set in 1980...
