Bitumen Extraction, Indigenous Land Conflicts, and Environmental Change in the Athabasca Oil Sands Region, 1963-1993
DownloadSpring 2021
This dissertation examines the first development phase of the Alberta oil sands industry from the 1960s to the early 1990s. It draws on public and private records from archives in Canada and the United States, the results of collaborative research with the Fort McMurray Métis, and oral history...

During the extraction of crude oil or bitumen, stable water-in-oil emulsions are inevitably formed. The emulsified water contains chloride ions and other organic acidic compounds that cause severe corrosion problems to the downstream plant equipment, creating operational and safety issues and...

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...

Boxed-in: Comparing Algorithms for Box-flight Mass-Balance Greenhouse Gas Flux Measurements from Mineable and In Situ Oil Sands Developments
DownloadSpring 2022
To combat global warming, Canada has committed to reducing greenhouse gases (GHGs) 40-45% below 2005 emission levels by 2025. Monitoring emissions and deriving accurate inventories are essential to reaching these goals. GHGs can be measured at a small scale, often using ground measurements which...

This dissertation examines the relationship between Canadian newspapers, the development of Alberta’s oil sands, and neoliberalism. It uses both content and discourse analysis to analyze coverage of oil sands development in six English-Canadian newspapers between October 1, 2005 and October 31,...

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...

Characterization of asphaltene molecular structures by cracking under hydrogenation conditions and prediction of the viscosity reduction from visbreaking of heavy oils
DownloadSpring 2013
The chemical building blocks that comprise petroleum asphaltenes were determined by cracking samples under conditions that minimized alterations to aromatic and cycloalkyl groups. Hydrogenation conditions that used tetralin as hydrogen-donor solvent, with an iron-based catalyst, allowed...

Characterization of Athabasca asphaltenes separated physically and chemically using small-angle X-ray scattering
DownloadFall 2010
Athabasca asphaltenes were characterized using small-angle X-ray scattering (SAXS) with synchrotron radiation. Two methods were used to separate asphaltenes from Athabasca bitumen. Conventional chemical separation by precipitation with n-pentane, and physical separation realized by passing...

Fall 2013
The high degree of variability of oil sands ores can be attributed to a mixture of different geological end members, i.e., estuarine sand, estuarine clay, marine sand and marine clay. This study focused on the mineralogy, especially of clay minerals, and toluene insoluble organic matter, referred...
