At different stages during the extraction of bitumen from the Athabasca oil sands, the removal of unwanted fine solids whether suspended in aqueous or non-aqueous liquids continues to present serious challenges to the oil sands industry. These fine solids are unique in that their colloidal...

Archipelago Model Compound Synthesis by Rhodium-catalyzed Annulations of Island-tethered Alkynes with Aromatic Substrates
DownloadFall 2022
Asphaltenes are the most complex constituents in bitumen. They are distinguished from other components in bitumen by high density, high viscosity and a strong tendency to form aggregates in solutions. Asphaltene aggregates may precipitate as a result of small environmental changes, which is...

Bitumen recovery by the water-based extraction process produces waste streams known as tailings. When discharged into the tailing ponds, the coarse solids in the tailings stream settle out quickly, while the fine solids accumulate over years of settling to a solids content of 30-35% by weight....

This thesis introduces a model emulsion that replicates the physical features of steam-assisted gravity drainage (SAGD) reservoir emulsion. Moreover, a framework was presented which enables adjusting the emulsion properties such as dynamic viscosity, size of the droplets, kinetic stability, and...

Investigating Light Solvent Aided Process in Cold Lake Oil-Sand Reservoir Using Experimental and Numerical Approaches
DownloadSpring 2019
Steam assisted- gravity drainage (SAGD) is the main in-situ bitumen recovery process in which saturated steam is injected into the bitumen zone. However, it has some drawbacks, which include high-energy consumption and significant environmental concerns. Solvent Aided Process (SAP) is a method...

Asphaltenes are the heaviest and most polar group of molecules in crude oil. Colloidal behaviors of asphaltenes, including the aggregation and interfacial behaviors, have impacts on many petroleum production processes. For example, the aggregation of asphaltenes can lead to problems such as...

Optimization of steam/solvent injection methods: Application of hybrid techniques with improved algorithm configuration
DownloadFall 2012
Heavy oil and bitumen recovery processes need to be optimized in order to increase the recovery, reduce costs, and minimize the environment impact. Most of the optimization studies published in petroleum engineering literature focus on a few design parameters by combining the elements of...

Steam-Solvent Coinjection for Bitumen Recovery under Reservoir Heterogeneity with Consideration of Water Solubility in Oil
DownloadFall 2017
The main objective of this research is to determine if expanding solvent-steam assisted gravity drainage (ES-SAGD), wherein a small quantity of a condensable solvent is coinjected with steam, can be a better alternative to SAGD in highly heterogeneous formations. Specifically, three previously...

Asphaltenes are the heaviest fraction of crude oils. Asphaltenes are composed of carbon rings with aliphatic side chains, and they are precipitated from crude oils with small-chain alkanes, such as pentane or heptane. This complex class of molecules can be problematic during oil extraction,...
