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...

Rheology of Bitumen at the Onset of Asphaltene Aggregation and its Effects on the Stability of Water-in-Oil Emulsion
DownloadFall 2015
Asphaltenes are the heaviest fraction of bitumen. Asphaltenes not only play an important role in the high viscosity of bitumen but also in the water-in-oil (W/O) emulsion stability. Nevertheless, their exact function in the stability mechanism of W/O emulsion still remains unresolved. It is...

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....

Study of biodiesel-assisted ambient aqueous bitumen extraction (BA3BE) for hydrocarbon production from mineable oil sands
DownloadFall 2019
Surface mining followed by Clark’s hot water bitumen extraction (HWBE) process has been employed in the current mineable oil sands industry for massive bitumen production. This method is faced with numerous challenges such as high energy consumption, limited bitumen quality, production from...

Fall 2010
To better understand bitumen conditioning stage in oil sands extraction process a flow cell was designed to study bitumen liberation directly from sand grains, using real oil sand ore. A high-grade oil sand ore was subjected to various water temperatures and pH values to examine the bitumen...
