Spring 2010
The demand for accurate bitumen-pentane mass transfer data was the main motivation behind this research. Difficulties such as complex phase behavior, high viscosity and opacity of the hydrocarbon invariably lead to failure of conventional techniques to measure mass transfer coefficients...

Methane Production and Emission Mitigation in Oil Sands Tailings Concurrent with Hydrocarbon Degradation under Nitrogen Limited Conditions
DownloadFall 2020
Alberta’s oil sands generate large volumes of tailings from bitumen ore processing. These tailings ponds produce biogenic methane, which can be measured across 60-80% of the tailings surface. Based on current surface area data and emissions studies, tailings ponds could account for 8% of Canada’s...

Microwave Heating Of Non-Aqueous Oil Sands Extraction Gangue: Study Of Optimal Cyclohexane-Water Mass Ratio And Solvent Recovery Rate
DownloadFall 2023
Non-aqueous bitumen extraction processes (NAE) of mined oil sands ore have been investigated to circumvent the environmental and operating limitations of the current hot water-based technology. However, one primary challenge of NAE is a solvent recovery that meets environmental and economic...

Malamace da Silva, Victor Hugo
The oil sands of Western Canada are among the most abundant and economically important unconventional petroleum resources. Hydrocarbon extraction from oil sands is conducted using warm water or in situ technologies that face considerable environmental challenges. Oil sands can also be valorized...

Spring 2010
Molecular dynamics simulation and density functional theory were applied to calculate heats of immersion (ΔHimm) of n-heptane, toluene, pyridine and water on two model sand surfaces and two model clay surfaces. Our results indicated that water showed the highest ΔHimm for the model clay surfaces...

Natural Zeolite Catalysts for the Integrated Cracking, Waterless Extraction and Upgrading of Oilsands Bitumen
DownloadSpring 2012
Canadian oilsands bitumen represents one of the largest petroleum reserves in the world, but extraction of that resource raises significant environmental, operational and quality-related challenges. Current extraction processes are water intensive, generating high volume tailings ponds that are...

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...

Spring 2013
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 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...

On Organic Liquid Crystal Transfer from Bitumen-Rich to Water-Rich Phases: A Combined Laboratory and SAGD Field Study
DownloadSpring 2014
Hydrocarbon-based liquid-crystal domains were observed in unreacted heavy fractions extracted from Athabasca bitumen and bitumen derived hydrocarbon resource fractions. Transfer of these organic crystalline domains to the water-rich phase during SAGD production is explored here because there...
