Spring 2010
Molecular dynamics simulation and density functional theory were applied to calculate heats of immersion (ΔHimm) of n-heptane, toluene, pyridine and water on two model sand surfaces and two model clay surfaces. Our results indicated that water showed the highest ΔHimm for the model clay surfaces...

Near-Wellbore Salinity Effect on Sand Control Plugging by Fines Migration in Steam-Assisted Gravity Drainage Producer Wells
DownloadFall 2023
Sand control screens are necessary for steam-assisted gravity drainage (SAGD) wells drilled into oil sands to prevent sand production. However, the accumulation of mobilized fine particles near the wellbore can result in screen plugging, adversely affecting the well's flow performance. This...

Novel feed enzyme delivery method: Binding exogenous feed enzymes to Bacillus spores to improve enzyme stability and total tract digestibility
DownloadFall 2018
The effects of binding feed enzymes to Bacillus subtilis (strain RK28) spores on enzyme stability and digestion in cattle were studied in comparison to unbound enzymes. Optimal conditions for adsorbing six different enzymes (α-amylase, β-glucanase, feruloyl esterase, phytase, purified xylanase,...

Spring 2013
A major barrier to reclamation after oil sands mining is lack of commercially available, diverse native plant seeds and propagules for revegetation. Potential of LFH (forest floor material) developed on coarse textured soil for establishing native plants and how salvage, placement and storage...

Oil Upgrading by Molecular Rearrangement and Cracking: A Study Using Model Compounds and Natural Chabazite
DownloadFall 2015
As demand for fuel increases, new technologies that can convert heavy oil and bitumen into light fuels are needed. Natural zeolites have been proven to catalyze reactions that decrease molecular weight, density, nitrogen, and metals content as well as vacuum residue content when mixed with raw...

Phase Behavior, Adsorption Behavior and Interfacial Properties of Fluids in Shale Reservoirs
DownloadFall 2018
Shale oil/gas resources are becoming an increasingly important energy resource. Compared to conventional reservoirs, shale generally consists of a large proportion of organic matters. Organic matter is mainly comprised of kerogen, within which a significant amount of nanopores may reside. Due to...

Fall 2020
Oil sands mining is a significant disturbance in the Canadian boreal forest. One objective for reclamation after mining is to create a self-sustaining ecosystem, which includes establishing a native plant community. For this thesis, study one evaluates the different plant assembly mechanisms,...

Possible thunderstorm modifications caused by the Athabasca oil sands development and the Canadian Shield
DownloadFall 2017
Thunderstorms are common in boreal forest regions and can cause dangerous hazards such as lightning, forest fires, hail, wind, and flooding. Significant research has been conducted to help predict thunderstorms to mitigate or avoid the hazards and damage. The development of thunderstorms...

Production and Application of Different Waste-derived Sustainable Materials for the Removal of Naphthenic Acids Related to Oil Sands Process Water
DownloadSpring 2024
Oil sands process water (OSPW) is generated in a large volume during the bitumen extraction process from the oil sands. Naphthenic acids (NAs) are recalcitrant compounds that contribute to the toxicity of OSPW, which need effective treatment before being released into the environment. In the...

Productivity and carbon accumulation potential of transferred biofilms in reclaimed oil sands-affected wetlands
DownloadSpring 2011
Biofilms are significant contributors to primary production, nutrient cycling, bio-stabilization and the food web of wetland ecosystems. Photoautotrophic biomass (PB) and primary production (PP) were determined for biofilms exposed to various treatments and materials in wetlands near Fort...
