Assessing the long-term impact of acid deposition and the risk of soil acidification in boreal forests in the Athabasca oil sands region in Alberta, Canada
DownloadFall 2012
Significant amounts of SO2 and NOx have been emitted from the Athabasca oil sands region (AOSR) in Alberta, Canada, in the past several decades. The impact of acid deposition on forest ecosystems and the risk of soil acidification were assessed in jack pine (Pinus banksiana) and trembling aspen...

Assessing the mobility of metals and dissolved organics in pit-lake models containing PASS-treated fluid tailings
DownloadSpring 2024
Oil sands surface mining produces considerable quantities of fine fluid tailings (FFT). Several reclamation strategies are being investigated to address the environmental concerns related to long-term FFT storage. One promising sustainable tailings management approach is End Pit Lake (EPL);...

Biological Treatment of Naphthenic Acids and Other Organic Compounds in Oil Sands Process-Affected Waters
DownloadFall 2014
The Alberta oil sands contain one of the world’s largest reserves of oil - over 169 billion barrels of bitumen are economically recoverable with current extraction technologies. Surface mining, whereby the ore is extricated from the earth and bitumen is obtained via a hot water extraction...

Bioremediation of oil sands process affected water sourced naphthenic acid fraction compounds
DownloadFall 2020
Current development of Alberta’s oil sands region requires large volumes of water, leading to an abundance of oil sands process affected water (OSPW). OSPW contains naphthenic acid fraction compounds (NAFCs) which have been found to contribute extensively to OSPW toxicity. Degradation of this...

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...

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...

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...

Characterization of Clay Minerals in the Athabasca Oil Sands in Water Extraction and Nonaqueous Solvent Extraction Processes
DownloadFall 2011
Production of oil from the second largest oil deposit in the world, i.e., the Alberta oil sands containing approximately 13% of total proven oil reserves in the world (169.9 billion barrels), has been shown to be significantly influenced by clay minerals. Clay minerals in particular play a key...

Fall 2011
Fluorescence technology was examined as an analytical tool for identifying naphthenic acids in process-affected water. The fluorescence signal from process-affected water was narrowed down to the extractable organic acid fraction, known to contain naphthenic acids. A characteristic intensity...

Characterization of the dissolved organic matter in steam assisted gravity drainage boiler blow-down water
DownloadFall 2012
The presence of high concentrations of dissolved organic matter (DOM) and total dissolved solids (TDS) in the boiler blow-down water (BBD) causes severe equipment fouling during the SAGD operation. For effective BBD management, a detailed understanding of the BBD chemistry is important. In this...
