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...

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...

Challenges of utilizing municipal compost as an amendment in boreal forest reclamation subsoil material
DownloadFall 2018
Forest reclamation sites are often located in areas not suited for agriculture and therefore have poor soil conditions. To assist in the rehabilitation of forests on these types of sites, organic amendments can be used. Close to large urban centers, compost derived from municipal organic waste...

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...

Pennetta de Oliveira, Leonardo
Bitumen has been extensively extracted from oil sands through the Clark Hot Water Extraction (CHWE) process. This extraction process uses hot water and alkaline conditions to remove bitumen from oil sands ores. The tailings produced by this process are mixtures of sand, clays, residual bitumen,...

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 2010
A study was conducted to evaluate the properties and processes influencing the rate and magnitude of volume decrease and strength gain for oil sand fine tailings resulting from a change in bitumen extraction process (caustic versus non-caustic) and the effect of adding a coagulant to caustic fine...

Fall 2018
Improving water quality by inducing agricultural producers to implement Beneficial Management Practices (BMPs) is one of the top environmental concerns in Canada and worldwide. Conservation auctions can be a cost-effective mechanism to achieve this goal. The first two papers in this thesis focus...
