Applications of Remote Hyperspectral Sensing in the Characterization of Alberta's Oil Sands Tailings
DownloadSpring 2016
The bitumen production from oil sands surface-mining operations produces large volumes of mineral wastes called tailings. Characterization of the oil sands tailings is of importance to monitor their state for trafficability and reclamation issues, to assess the tailings operation performance, and...

Spring 2016
A study was implemented to evaluate different alternatives of soil cover systems for the closure of approximately 1539 Mt of waste rock at the Antamina Mine (Peru). The soil covers were designed to limit water percolation to the underlying waste rock, by combining a store/release and low...

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...

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...

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...

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...

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...
