Spring 2013
This thesis is concerned with the effect of mechanical wear on superhydrophobic surfaces (SHS). This work, for the first time, systematically details the simultaneous surface topography and wetting behavior changes upon abrasion of SHS. The process of physical abrasion was also simulated on the...

Spring 2018
Superhydrophobic interfaces, due to their unique water repellent and self-cleaning properties, are attracting a wide-spread interest for implementation in a variety of applications, including self-assembly based fabrication methods, nano/microfluidics, and solar energy harvesting. To facilitate...

Wave Speed Measurements of Grosmont Formation Carbonates: Implications for Time-Lapse Seismic Monitoring
DownloadFall 2019
The Grosmont Formation is a Devonian-aged carbonate platform complex that is estimated to hold over 64.5 billion m3 (406 billion bbl) of bitumen in place, accounting for a significant portion of Canada’s total hydrocarbon reserves. Despite this, the Grosmont formation has largely been undeveloped...

Fall 2012
The kinetics of vapor phase cracking of bitumen derived heavy gas oil and the quality of liquid products were investigated at temperatures of 600-700 °C. Fixed and condensed gases were analyzed by gas chromatography. The quality of liquid products was characterized using simulated distillation,...

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...

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,...

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...

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...

Spring 2022
In predicting oil and gas recovery, researchers develop models primarily focusing on macro- or milli-scale flows by applying Navier-Stokes types solutions and no-slip boundary conditions. They compare or cross-check their models to known experimental results available in the literature for larger...
