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...

Spring 2017
Dewatering of the oil sands mature fine tailings (MFT) is studied through pressure filtration following treatment by dual polymer flocculants. Polymer pairs consisting of anionic polyacrylamide (A3335) and cationic polyDADMAC (Alcomer 7115), and A3335 and non-ionic polyethylene oxide (PEO) are...

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...

Protecting Worker Safety in Alberta by Enhancing Hazard Identification and Control for Hazards Associated with Tailings Facilities, Dams, and Systems
DownloadSpring 2019
My research was motivated by a fatality that occurred at an oil sands tailings operation on January 19, 2014, when a worker drowned in an underground cavern which formed under a leaking tailings transport system. At the time of the incident, the organization and workers did not know that ground...

Reclamation of Unconventional Oil Processed Water through the Adsorption of Naphthenic Acids by Carbon Xerogel
DownloadFall 2017
This study examines the use of carbon xerogel (CX) material for the adsorption of naphthenic acids (NAs). The adsorption of NAs is crucial for the reclamation of unconventional oil processed water, more specifically Alberta’s oil sands process-affected water (OSPW). CX material is synthesized at...

Removal of Organic and Inorganic Contaminants from Oil Sands Tailings using Carbon Based Adsorbents and Native Sediment
DownloadFall 2013
The extraction and refinement of oil sands bitumen produces substantial quantities of liquid tailings and solid coke. Tailings contain metals and naphthenic acids, which require remediation before mine closure. Adsorption is a potential remediation technique which may reuse stockpiled petroleum...

Spring 2016
Non-aqueous extraction technologies are currently being investigated as an alternative to the conventional water based process for extracting bitumen from oil sands. The reduced dependence on fresh water and land for creation of tailing ponds makes non-aqueous technologies a greener alternative....

Study of Bio-densification Process in Oil Sands Tailings: Modeling and Experimental Validation
DownloadFall 2012
Slow densification of mature fine tailings (MFT) is one of the major challenges in reduction of tailings inventory, pore-water recovery and reclamation of tailings for oil sands industry. Bio-densification is a new treatment method in which densification of tailings is accelerated through...

Spring 2017
This thesis is composed of two parts. The first part deals with the fabrication of antifouling membranes based on polyethersulfone (PES) and cellulose nanocrystals (CNC). PES/CNC nanocomposite membranes were prepared by non-solvent phase-inversion method. The effects of PES/CNC composition on...

Subsurface Geophysical Characterization of the Crystalline Canadian Shield in Northeastern Alberta: Implications for Geothermal Development
DownloadFall 2013
In northern Alberta, existing heat flow and geothermal gradient studies suggest that using geothermal heat in oil sands processing would require deep drilling of the crystalline Canadian Shield. Using a 2.36 km deep borehole located near Fort McMurray, the goal of this study is to investigate the...
