.... At original condition, the viscosity of Athabasca bitumen is over one million centipoises. The key parameter to produce this bitumen is to lower its viscosity and mobilize it to the production well. There are two main techniques for the reduction of bitumen viscosity: first is to increase heavy oil...

... of propane and CO 2 with Athabasca bitumen are considered. Saturation pressures were measured in a PVT cell and the density and viscosity of the saturated liquid phase were determined at temperatures between 0 and 90 °C and pressures up to 5 MPa. Data are reported for CO 2 -bitumen, propane-bitumen...

... (isonicotinic acid) are also shown in Figure 3. Figure 4 shows a substituted isonicotinic acid isolated by Thimm1 from an Athabasca SAGD project, so such structures do exist in Athabasca bitumen. 3. Acid-catalyzed decarboxylation, shown in Figure 3 scheme 2, is the common mechanism for many aromatic acids...

... LTO were simulated, using Saturates, Aromatics, Resins and Asphaltenes (SARA) fractions to characterize the Athabasca bitumen. Concentration profiles and coke deposition for individual temperatures were matched for isothermal experiments from 60 °C to 150 °C. Based on these results, Ramped Temperature...

... in the 180–240 degree range. Introduction The solvolytic reaction of Athabasca bitumen with steam condensate has been observed since the earliest days of piloting the recovery of this bitumen resource. The first laboratory studies were performed by Hyne et.al. 1 , who coined the now widely-used term...

... framework, for the diffusion coefficient of carbon dioxide in Athabasca bitumen has been reported. 5 The different experimental methods for the diffusivity of gases in bitumens can be broadly classified into the direct and indirect methods. The direct methods, based on the determination...

This paper will concentrate on the compositional changes of Athabasca bitumen in contact with nitrogen and air. The experiments were performed in an oscillating batch reactor with or without core...

... process is also based on a paraffinic solvent. To optimize these processes, data is required on asphaltene precipitation from heavy oils or bitumens diluted with n-alkanes. In this work, the onset and amount of asphaltene precipitation from Athabasca bitumen were investigated in a PVT cell using three...

... Abstract Two kinetic models were developed to describe thermal cracking and low temperature oxidation (LTO) reactions of Athabasca bitumen for the in situ combustion process. These unified kinetic models can describe the compositional changes in the Athabasca bitumen under thermal cracking...

... processes. The reversibility of asphaltene precipitation is also examined. EXPERIMENTAL Chemicals and Materials Athabasca bitumen was obtained from Syncrude Canada Ltd. and Cold Lake bitumen was obtained from Imperial Oil Ltd. The Athabasca bitumen is an oil sands bitumen that has been processed to remove...
