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...

Fall 2012
Unwanted phase separation of asphaltenes poses significant challenges in production and processing of heavy oils and bitumen. The analysis and prediction of asphaltene precipitation behaviors and asphaltene-diluent interactions are typically treated either from a solution thermodynamics or a...

Oil sands mining is a significant disturbance in the Canadian boreal forest. One objective for reclamation after mining is to create a self-sustaining ecosystem, which includes establishing a native plant community. For this thesis, study one evaluates the different plant assembly mechanisms,...

Porosity and permeability in the Graminia Formation, Upper Devonian Winterburn Group in the Germain Field, northeastern Alberta
DownloadFall 2014
The Upper Devonian Graminia Formation (Winterburn Group) found in the Germain Field of northeastern Alberta includes the Blueridge Member (Frasnian) and the Upper Graminia Member (Famennian). A green silty-shale paleosol overlies the formation in this area. The bitumen-bearing dolostones of this...

Possible thunderstorm modifications caused by the Athabasca oil sands development and the Canadian Shield
DownloadFall 2017
Thunderstorms are common in boreal forest regions and can cause dangerous hazards such as lightning, forest fires, hail, wind, and flooding. Significant research has been conducted to help predict thunderstorms to mitigate or avoid the hazards and damage. The development of thunderstorms...

Steam-assisted gravity drainage (SAGD) has proved to be a technically and commercially successful methodology for recovering heavy-oil in Canada. At present, there are 22 commercial SAGD projects with over 300 pads and 2,700 well pairs, contributing to over 1.5 million bbl/day of production. The...

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...

Oilsands bitumen produced from Alberta, Canada contains 14–20 wt.% n-pentane insoluble asphaltenes. Separation of asphaltenes from the bitumen by solvent deasphalting has the benefit of improving the properties of the deasphalted oil compared to the bitumen, for example, by decreasing its...

Probing Challenges of Asphaltenes in Petroleum Production through Extended−SARA (E−SARA) Analysis
DownloadSpring 2019
Asphaltenes are polyaromatic compounds present in crude oils, which are defined as being soluble in aromatic solvents and insoluble in n−alkanes. The partition of self−associated asphaltene aggregates at oil−solid and oil−water interfaces is the root cause of a number of major problems...

Probing Deformable Oil-Water Interfaces by Atomic Force Microscopy and Cascade Partial Coalescence Measurements
DownloadFall 2016
Phase separation of stable oil-in-water and water-in-oil emulsions poses major challenges for a variety of industries, including the petroleum industry. The stability and destabilizing of petroleum emulsions highly depend on interfacial properties such as surface/interfacial charges, interfacial...
