Fall 2021
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...

Combating the current and incoming climate catastrophe demands a reckoning with the forces that continue to prevent meaningful changes to the fossil fuel paradigm. Actors benefitting from the exploitation of fossil fuels have been consistent in their strategic efforts to actively affect policy...

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...

Turbidity Mitigation in an Oil Sands End Pit Lake through pH Reduction and Fresh Water Addition
DownloadFall 2016
The remediation of oil sands wastes such as fluid fine tailings (FFT) and oil sands process-affected water (OSPW) are of increasing concern in the oil sands industry. End pit lakes are one remediation option currently being researched at commercial scale in Base Mine Lake (BML) operated by...

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...

Understanding the Role of Caustic Addition: A Comparison of Sodium Hydroxide and Ammonium Hydroxide
DownloadSpring 2012
To understand the role of caustic addition and its effect on the bitumen extraction process, a novel flow cell and a Denver Cell extraction unit were utilized. This allowed for the comparison of sodium hydroxide and ammonium hydroxides effect on real oil sands ores. Several ores (A1, C-ore,...

Use of a solvent in the oxidative desulfurization of bitumen via autoxidation; effects on viscosity and oxidation
DownloadSpring 2014
This work describes the effect that including a solvent in the reaction media of the autoxidation of Cold Lake bitumen has on the viscosity and also on the oxidation degree reached. The comparison of viscosity was performed both in the basis of equal residence time and equal oxygen conversion...
