Assessment of Greenhouse Gas Emission Mitigation Potential and Abatement Costs of Alternative Technology Options for Oil Sands
DownloadSpring 2020
In the last several decades societies have gained an increasing level of awareness and scientific understanding of the impact of anthropogenic greenhouse gas (GHG) emissions on average global temperatures and the negative results of those temperatures increasing. Many governments, including...

Bitumen Extraction, Indigenous Land Conflicts, and Environmental Change in the Athabasca Oil Sands Region, 1963-1993
DownloadSpring 2021
This dissertation examines the first development phase of the Alberta oil sands industry from the 1960s to the early 1990s. It draws on public and private records from archives in Canada and the United States, the results of collaborative research with the Fort McMurray Métis, and oral history...

Characterization of Soil Spatial Heterogeneity and Improvement of Capping Materials for Oil Sands Mine Reclamation
DownloadFall 2018
Surface mining in the Athabasca Oil Sands Region (AOSR), Alberta, Canada creates a large-scale ecosystem disturbance requiring ‘land reclamation’. Mining approvals require that land reclamation returns the sites to an equivalent land capability class, but this goal has proven challenging to...

The oil-based drilling fluids are mainly used to explore hydrocarbon resources. During the drilling operation, a significant amount of oil-contaminated drill cuttings, which are crushed rocks, sands and clays mixed with the drilling fluids, are transported to the surface. In order to reduce the...

In order to determine the degradation of Naphthenic Acids (NAs) in oil sands process-affected water (OSPW), a series of semi-batch ozonation experiments have been conducted resulting in a maximum reduction of NAs greater than 99%. Compared to the high NAs removal, the reduction of both COD and...

Evaluating the Biogeochemical and Geotechnical Behavior of Oil Sands Tailings in Pit Lakes and Mitigating Pit Lake Turbidity with Biofilms
DownloadFall 2023
Permanent storage and reclamation of oil sands mine waste (fluid fine tailings, FFT) in pit lakes has been proposed by industry. Pit lakes are considered best practice in terms of geotechnical stability, however, there are numerous challenges and knowledge gaps surrounding this proposed oil sands...

Fabrication of Graphene-based Nanocomposite Membranes for Treatment of Process-affected Water
DownloadSpring 2020
Membrane separation processes are extensively used for separation of solutes such as ions, colloids, macromolecules, and organic matter from water. Among various membrane technologies, ultrafiltration (UF) and nanofiltration (NF) are progressively being employed for elimination of organic matter...
