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....

Salt Affected Soils And Their Relationships With Plant Communities On Reclamation Well Sites
DownloadFall 2020
Salt affected soils are common around the world from natural causes or anthropogenic activities. Over 1030 million hectares of land worldwide are affected by salt or at risk of being affected. In Alberta, saline and sodic soils may occur with oil and gas production, increasing the risk of...

Fall 2017
The by-product slurry resulting from the bitumen extraction process from oil sands sources, known as tailings, holds substantial amount of water along with clays and fugitive bitumen. Current polymer-based dewatering technologies are centred on acrylamide-based polymers such as polyacrylamide...

Social-ecological reclamation in the Northwest Territories: A framework for healing human-caribou relations
DownloadFall 2018
The impacts of mining activity on human-caribou relationships in the Northwest Territories have been a focus of study in both the natural and social sciences for decades. Guided by Łutsel K’e Dene First Nation elders and harvesters, this study used dendrochronology methods and best practices for...

Study on Adsorption of Inorganic-organic Hybrid Polymers and Flocculation of Oil Sands Tailings
DownloadSpring 2013
Two inorganic-organic hybrid polymers, Al(OH)3-polyacrylamide (Al-PAM) and Fe(OH)3-polyacrylamide (Fe-PAM) were synthesized and used in flocculating model tailings (5 wt% kaolin suspensions) and laboratory extraction tailings. For comparison, a commercial anionic flocculant, partially hydrolyzed...

Synthesis and Characterization of Amylopectin-grafted Polyacrylamide (AP-g-PAM) Flocculants for Dewatering of Oil Sands Mature Fine Tailings (MFT)
DownloadSpring 2018
Oil sand mining continues increasing in Alberta and bitumen production from surface mining is predicted to reach 257,600 m3/day by 2026 (a 41.3% increase compared to 2016), generating a large amount of tailings that need to be stored in tailing ponds. The challenging part of tailing management is...

Tarring the Oil Sands: The Evolution and Emergence of ENGO Opposition in Alberta’s Oil Sands and Social Movement Theory
DownloadFall 2012
ABSTRACT: The Alberta oil sands represent tremendous economic growth and prosperity for Alberta and Canada but their development does not come without cost. Environmental Non-Governmental Organizations (ENGOs), specifically the Pembina Institute and Greenpeace, have brought significant attention...

Fall 2011
This study has attempted to measure the economic impacts of chronic wasting disease (CWD) on Alberta hunters, in the study region of the Eastern to South-Eastern border of the province. Two years of stated preference and revealed preference data were collected and choice behaviour modelled using...

Spring 2022
This project sought to determine the effect of grazing management decisions on operation wealth; specifically, to determine both the wealth maximizing system for producers and to determine the impact on producers who adopt more intensive management systems. Adoption of four grazing management...
