Spring 2010
The technique of Inverse Gas Chromatography (IGC) was employed for the study of the interactions between various organic solvents with various types of the major inorganic materials (clay minerals and sand) found in Alberta’s oil sands. Heat of adsorption (-∆H) was measured for each solvent with...

Spring 2014
Environmental concerns about water-based extraction necessitate the development of an alternative non-aqueous extraction method. One of the challenges that any non-aqueous extraction process is encountered is the elimination of suspended fine solids from solvent-diluted bitumen. This study...

At different stages during the extraction of bitumen from the Athabasca oil sands, the removal of unwanted fine solids whether suspended in aqueous or non-aqueous liquids continues to present serious challenges to the oil sands industry. These fine solids are unique in that their colloidal...

This work investigated different acid catalysts and olefinic alkylating agents for the alkylation of an industrial asphaltenes feed. The working hypothesis was that alkylation would change the solubility parameter and increase the H/C ratio of asphaltenes sufficiently to cause some asphaltenes...

An Alternate Indicator System for Nutrient Supply as Part of Ecosystem Function, a Component of Reclamation Success in the Athabasca Oil Sands Region
DownloadFall 2017
Northeastern Alberta faces the challenges of reclaiming a vast area that has been disturbed my oil sands mining, cumulatively 896 km2 and increasing as of December 2013. The limited resources available for reclamation and expensive costs of undertaking the process necessitates that reclamation be...

An Examination of the Effect of Diluent on Microbial Dynamics in Oil Sands Tailings and the Mechanistic Insight on Carbon Dioxide-mediated Turbidity Reduction in Oil Sands Surface Water
DownloadFall 2019
Oil sands fluid fine tailings (FFT) are comprised of sand, silt, clay, residual organics, salt, trace metals and process-affected water (OSPW). In order to accommodate and remediate large amounts of FFT, a full-scale demonstration pit lake, where FFT was capped with a mixture of OSPW and fresh...

Spring 2013
The surface mining of oil sand ore requires the use of huge shovels and 400-tonne capacity trucks to transfer the mined ore to the slurry preparation plant, where water and additives are added to the crushed ore. The oil sand slurry is then transported to the extraction section and simultaneously...

An Integrated Approach for Sustainability Assessment: The Wa-Pa-Su Project Sustainability Rating System
DownloadFall 2014
As global demand for energy continues to rise, unconventional petroleum extraction and production of petroleum substitutes are both becoming more necessary. Development and operation of unconventional oil projects can have considerable social, economic, and environmental impacts. For example, one...

An Integrated Optimization Model for Strategic Open-Pit Mine Planning and Tailings Management
DownloadFall 2014
Badiozamani Tari Nazari, Mohammad Mahdi
A strategic mine planning model determines the best order of extraction and destination of material over the mine-life, in a way that maximizes the net present value of the produced minerals. In case of oil sands open-pit mining, further processing of the extracted oil sands generates massive...

An Investigation of Potential Weed Management Practices and Multivariate Assessment Parameters for Alberta's Oil Sands Reclamation Efforts
DownloadSpring 2018
Reclamation efforts that promote the re-establishment of native tree and plant communities subsequent of large-scale oil sands mining land disturbances are crucial in restoring natural ecosystems. It is important that reclamation procedures capable of facilitating the establishment of native...
