Spring 2015
The minable oil sands extraction process can be understood on a scale of a single oil sand grain. When the oil sand ore is mixed with warm water, each sand granule is initially covered with bitumen film which ruptures under the composite effect of shear and interfacial forces, while water...

Fall 2011
The growing interest in the oilsands bitumen reserves, a large portion of which is unattainable by current industrial processes, has generated a need for an improved process for oilsands extracting and upgrading. The effects of using chabazite as a catalyst for cracking and upgrading of oilsands...

At the heart of heavy oil and bitumen upgrading, thermal conversion technologies are found. One such process is visbreaking where bitumen is thermally converted into lighter materials. However, the conversion by visbreaking is limited by the onset of the formation of solid carbonaceous materials...

Colloid Science of Sand Remediation: A Study Motivated by the Non-Aqueous Extraction of Bitumen from Oil Sands
DownloadFall 2014
The current water-based method of bitumen extraction requires withdrawal of fresh water from the Athabasca River — a practice which leads to the continual buildup of tailings ponds and other environmental concerns. As Alberta’s bitumen production is expected to more than double by 2020, there is...

Fall 2013
Bitumen, as one of the most important unconventional sources of energy, has long been an attractive source for production of liquid fuels. It is important to improve the yield and quality of the useful products resulting from bitumen upgrading processes so that the best outcome can be achieved...

Fall 2014
The formation of stable water-in-oil emulsions during bitumen extraction poses problems for water separation from diluted bitumen, which leads to equipment corrosion and catalyst fouling in downstream operations. Demulsifiers are used to break the stable emulsions and assist the separation of...

Development of an Experimental Apparatus for Studying the Effects of Acoustic Excitation on Viscosity
DownloadFall 2012
An experimental apparatus was developed capable of measuring changes in fluid viscosity occurring due to acoustic stimulation. Controls allowed measurements at simulated oil sand reservoir pressures and temperatures with near real-time data visualization. Calibration was performed...

Development of Solvent Selection Criteria Based on Diffusion Rate, Mixing Quality, and Solvent Retrieval for Optimal Heavy-Oil and Bitumen Recovery at Different Temperatures
DownloadFall 2015
Heavy-oil and bitumen recovery requires high recovery factors to offset the extreme high cost of the process. Attention has been given to solvent injection for this purpose and it has been observed that high recoveries are achievable when combined with steam injection. Heavier (“liquid”) solvents...

Fall 2020
Concerns over the environmental impacts of thermal production methods for bitumen and heavy oil have led to the exploration of alternative technologies including solvent-assisted production methods. While solvent-assisted production methods have been studied extensively, apparent diffusion rates...
