Malamace da Silva, Victor Hugo
The oil sands of Western Canada are among the most abundant and economically important unconventional petroleum resources. Hydrocarbon extraction from oil sands is conducted using warm water or in situ technologies that face considerable environmental challenges. Oil sands can also be valorized...

Asphaltenes are the heaviest component in crude oil and bitumen. The molecular interactions and interfacial behaviours of asphaltenes are closely related to many challenging issues in oil production, which are believed to play an important role in stabilizing water-in-oil (W/O) and oil-in-water...

Natural Zeolite Catalysts for the Integrated Cracking, Waterless Extraction and Upgrading of Oilsands Bitumen
DownloadSpring 2012
Canadian oilsands bitumen represents one of the largest petroleum reserves in the world, but extraction of that resource raises significant environmental, operational and quality-related challenges. Current extraction processes are water intensive, generating high volume tailings ponds that are...

The nature and structure of asphaltene nanoaggregates are frequently the subject of debate and speculation in the literature. The continental asphaltene nano-aggregate model, characterized by the presence of alkyl chains on their surface, and the archipelago nano-aggregate model, characterized...

On Organic Liquid Crystal Transfer from Bitumen-Rich to Water-Rich Phases: A Combined Laboratory and SAGD Field Study
DownloadSpring 2014
Hydrocarbon-based liquid-crystal domains were observed in unreacted heavy fractions extracted from Athabasca bitumen and bitumen derived hydrocarbon resource fractions. Transfer of these organic crystalline domains to the water-rich phase during SAGD production is explored here because there...

Fall 2015
Hydrocarbon-based liquid crystal domains have been identified in unreacted heavy fractions of petroleum from Athabasca bitumen and other hydrocarbon resources worldwide. These liquid crystal domains have also been shown to transfer from the hydrocarbon-rich phase to the water-rich phase during...

Large polycyclic aromatic nitrogen containing asphaltene model compounds, with molecular weights from 535 to 702 g/mol, were catalytically hydrogenated and hydrodenitrogenated in the presence of a commercial NiMo/γAl2O3 catalyst in a stainless steel batch reactor at 370 °C and 17.9 MPa total...

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...

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...
