Investigation of variation in oil sand properties via analysis of seismic and on-board truck data
DownloadFall 2014
The ever increasing size of mining equipment has caused many instability concerns both on board and in the ground underneath. This highlights the need for more in-depth knowledge of variation in the properties of the ground as it has direct influence on the durability and life span of mining...

Life Cycle Assessment (LCA) of Oil Sands-Derived Transportation Fuels Produced from the Vapor Solvent-Based Extraction Process
DownloadFall 2017
Soiket, Mohammad Ikthair Hossain
Oil sand is a mixture of sand, clay, water, bitumen and other minerals. Production of transportation fuels like gasoline, diesel, jet fuel, etc. from the oil sands reserved in deep underground reservoirs require external stimulant to lower the viscosity of bitumen. The established thermal...

Marsh reclamation in the oil sands of Alberta: providing benchmarks and models of vegetation development
DownloadFall 2014
A key objective of the Alberta oil sands industry is to reclaim the post-mined landscape to “equivalent land capability” (Harris 2007). Vitt and Bhatti (2012) proposed a restoration framework for boreal disturbances. They suggested that to increase chances of achieving ecosystem equivalency and...

The mining of oil sands ore and extraction of bitumen produces aqueous slurries containing bitumen, coarse sand and fine clays. The performance of key process units is highly dependent on the rheology of “carrier fluid”, which is comprised of the fine solids and water. Although viscosity is...

The focus of the research presented here was to directly measure actual evaporation rates from a tailings surface using a micrometeorological technique known as the eddy covariance method. Depending on the results, it would be determined whether current drying models need to be calibrated with...

This study assessed the geographic distribution of mercury in water, and biota of the Athabasca River, and in snow and vegetation in its watershed. Mercury in the snowpack was significantly elevated within 46km of oil sands development relative to greater distances. Mercury was significantly...

The impact of mixing on water removal from diluted bitumen and bitumen froth is studied, with the goal of maximizing demulsifier performance. The relative effects of bulk concentration, mixing intensity, mixing time and injection concentration on the demulsifier performance are evaluated. A...

This thesis focuses on formulating and analyzing non linear models for microbial dynamics vis-a-vis human and environmental health. Firstly, we develop and investigate a stoichiometric organic matter decomposition model in a chemostat culture that incorporates the dynamics of grazers. This...

Monitoring Macrophage Immune Gene Expression Profiles as an Early Indicator System for Examining the Bioactivity of Oil Sands Process Affected Waters
DownloadFall 2021
Oil sands process-affected waters (OSPW) are by-products of bitumen (i.e. oil) extraction from the oil sands located in northern Alberta. These large volumes of water are held in tailings ponds and cannot be released due to their potential toxic effects. Overall, tailings ponds and mining...

Natural and anthropogenic inputs of arsenic and selenium to the environment in the Athabasca Bituminous Sands Region
DownloadSpring 2019
Industrial development of the Athabasca Bituminous Sands (ABS) in northern Alberta, Canada, has raised concerns that emissions of arsenic and selenium to the surrounding landscape and waterbodies have been increasing over time. To test this hypothesis, a comprehensive study of arsenic and...
