Study of the Chinese loess and Siberian flood basalts: new global scale insights to the paleoclimate and geomagnetic field changes
DownloadSpring 2017
Paleomagnetism, in conjunction with other earth science methods, studies the behavior of the Earth's magnetic field, the drift of tectonic plate, climate and environmental changes. This thesis implements different applications of paleomagnetism to develop a technique to evaluate age for the...

Synergistic Role of Sodium Hydroxide and Sodium Citrate on Bitumen Slime Coating in Process Water
DownloadFall 2021
Sodium hydroxide (NaOH) is generally used as the primary processing aid in the water-based oil sands extraction for the recovery of bitumen. It was found by Syncrude Canada Ltd. that the combined use of sodium hydroxide and sodium citrate could effectively improve the bitumen recovery as compared...

The synthesis of functionalized quinolines is described herein. Utilizing condensation reactions, derivatized quinolines were prepared to serve as nitrogen-containing asphaltene islands. Basic halogenated phenylquinolines were synthesized via urea condensations. Highly substituted quinolines...

The lower Athabasca River valley in northeastern Alberta, famous for oil sands mining, was also the site of one of North America largest Ice Age floods. During deglaciation, a large proglacial lake, Lake Agassiz, drained catastrophically through the Athabasca River valley. This catastrophic flood...

The Biology of Sclerobionts and their Hosts: Comparing Biomechanical Experiments on Brachiopod Hosts to Sclerobiont Distribution Maps
DownloadFall 2014
Sclerobionts and their host organisms provide a great deal of information for palaeoecological and palaeoenvironmental studies. However, any interpretation of sclerobiont – host relationships depends on an understanding of the host’s orientation. In the past, distinction of host life and...

The Roles of Constituent Minerals and Residual Bitumen in the Filtration of Alberta Oil Sands Tailings
DownloadFall 2022
The dewatering of Alberta oil sands tailings is one of the most challenging problems faced by the oil sands industry. Despite significant efforts in the past several decades, the industry still lacks viable technologies that can quickly dewater and reclaim the oil sands tailings and eliminate...

Fall 2018
Canada has one of the largest oil reserves in the world, with around 3 trillion ultimate reserves in heavy oil. Even though, one of the major difficulties that Canadian Oil sands industry has faced over time is the transportation of bitumen due to its extremely high viscosity. Having this in...

Ultrasonic Characterization of Bitumen with Pressure and Temperature: Implications for seismic monitoring of the Grosmont Formation
DownloadFall 2018
The vastly untapped carbonate Grosmont Formation in north-eastern Alberta may hold in excess of a couple of hundred billion barrels initial volume of bitumen in place. Bitumen, an ultra-heavy hydrocarbon oil, possesses a density comparable to water, but a dynamic shear viscosity million times...

Understanding stability of water-in-diluted bitumen emulsions by colloidal force measurements
DownloadSpring 2011
Removal of emulsified water is a challenge in oil sands and heavy oil processing. The flocculation and coagulation of emulsified water droplets depend on the interactions between the water droplets covered mainly by asphaltenes and oil-contaminated fine solids. To quantitatively evaluate the...
