Morphological Effects of Water Soluble Polymer Flocculants Synthesized by Controlled Reversible-Deactivation Radical Polymerization for Treatment of Mature Fine Tailings
DownloadFall 2020
The bitumen reserves in Northern Alberta are a valuable asset, but extracting bitumen from oil sands via the Clark hot water process produces undesirable waste tailings. These tailings are transported to tailings ponds where the sand and clay particles are left to settle slowly, creating a...

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...

Oilsands tailings are a waste product comprising primarily a stable alkaline suspension of clay in water. This waste product of oilsands mining is environmentally hazardous to store and expensive to safely dispose of. This work presents two novel ideas for dealing with the waste. The first is...

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 Sands Reclamation With Woody Debris Using LFH Mineral Soil Mix And Peat Mineral Soil Mix Cover Soils: Impacts On Select Soil And Vegetation Properties
DownloadFall 2014
Prior to mining oil sands, soil is salvaged for reclamation and forest stands are harvested for their merchantable timber. Harvest operations leave large amounts of residual woody debris, which has been historically burned or mulched. Woody debris has significant ecological effects and can be...

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...

Persistence of subsoiling effects on the soil physical and hydraulic properties in a reconstructed soil
DownloadSpring 2016
Surface mining is one of the most significant forms of anthropogenic disturbance to natural and managed ecosystems. In Alberta, mining disturbs large areas in the Mixedwood Boreal natural region and recovery is often slow because of poor soil quality, specifically the high degree of compaction....

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,...

Commercial Magnafloc 1011and in-house synthesized Al-PAM were used as flocculants for model tailings, laboratory extraction tailings and tailings from paraffin froth treatment unit. The polymers were tested for their flocculation ability in settling and filtration. For model tailings, both...

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...
