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...

Fall 2015
Hydrocarbon-based liquid crystal domains have been identified in unreacted heavy fractions of petroleum from Athabasca bitumen and other hydrocarbon resources worldwide. These liquid crystal domains have also been shown to transfer from the hydrocarbon-rich phase to the water-rich phase during...

Organically-Modified Clay Minerals in Oil Sands: Characterization and Effect of Hydrothermal Treatment
DownloadFall 2017
The intimate association between bitumen components and clay minerals is an important feature of oil sands fine solids. These organically-modified clay minerals cause serious problems in Canadian oil sands production: hindering bitumen extraction, stabilizing water-in-bitumen emulsions, fouling...

Phase Behavior and Thermophysical Properties of Athabasca Bitumen and Athabasca Bitumen + Toluene Mixtures in Near-critical Water
DownloadSpring 2014
The phase behavior and thermophysical properties of heavy hydrocarbons + water at elevated temperatures underpins development and implementation of coordinated production and refining processes, where for example, bitumen is produced by a SAGD method (steam assisted gravity drainage) and the...

Fall 2015
Oil sands bitumen is increasingly recovered by injecting steam into reservoirs using the energy intensive Steam assisted gravity drainage (SAGD) process. Interest in improving recovery and energy efficiencies have led to an interest in injecting light hydrocarbons along with or instead of steam...

Spring 2017
Dewatering of the oil sands mature fine tailings (MFT) is studied through pressure filtration following treatment by dual polymer flocculants. Polymer pairs consisting of anionic polyacrylamide (A3335) and cationic polyDADMAC (Alcomer 7115), and A3335 and non-ionic polyethylene oxide (PEO) are...

Protecting Worker Safety in Alberta by Enhancing Hazard Identification and Control for Hazards Associated with Tailings Facilities, Dams, and Systems
DownloadSpring 2019
My research was motivated by a fatality that occurred at an oil sands tailings operation on January 19, 2014, when a worker drowned in an underground cavern which formed under a leaking tailings transport system. At the time of the incident, the organization and workers did not know that ground...

Fall 2018
There is a growing need to decrease the viscosity of bitumen using minimal diluent addition to reduce the cost of transportation. However, due to the inherently free radical rich nature of bitumen, even on exposure to low autoxidative conditions adverse effects on the viscosity and hardening of...

Remediation of bitumen-contaminated sand grains: development of a protocol for washing performance evaluation
DownloadSpring 2010
In the development of a non-aqueous bitumen extraction process, a major obstacle is solvent loss due to hydrocarbon attachment to the reject sand grains. A proposed solution to this problem is to wash (i.e. remediate) the oil-contaminated sand grains with water and surfactants. This research is...
