Challenges of utilizing municipal compost as an amendment in boreal forest reclamation subsoil material
DownloadFall 2018
Forest reclamation sites are often located in areas not suited for agriculture and therefore have poor soil conditions. To assist in the rehabilitation of forests on these types of sites, organic amendments can be used. Close to large urban centers, compost derived from municipal organic waste...

At the heart of heavy oil and bitumen upgrading, thermal conversion technologies are found. One such process is visbreaking where bitumen is thermally converted into lighter materials. However, the conversion by visbreaking is limited by the onset of the formation of solid carbonaceous materials...

The high degree of variability of oil sands ores can be attributed to a mixture of different geological end members, i.e., estuarine sand, estuarine clay, marine sand and marine clay. This study focused on the mineralogy, especially of clay minerals, and toluene insoluble organic matter, referred...

Characterization of Clay Minerals in the Athabasca Oil Sands in Water Extraction and Nonaqueous Solvent Extraction Processes
DownloadFall 2011
Production of oil from the second largest oil deposit in the world, i.e., the Alberta oil sands containing approximately 13% of total proven oil reserves in the world (169.9 billion barrels), has been shown to be significantly influenced by clay minerals. Clay minerals in particular play a key...

Fluorescence technology was examined as an analytical tool for identifying naphthenic acids in process-affected water. The fluorescence signal from process-affected water was narrowed down to the extractable organic acid fraction, known to contain naphthenic acids. A characteristic intensity...

Understanding mineralogy and surface properties of fine solids is vital in oil sands processing and tailings management. Fine solids in oil sands are often contaminated by tightly bound organic matter (OM) originally or during hydrocarbon removal, thereby increasing surface hydrophobicity and...

CO2-Responsive Surfactants for Enhancing Heavy Oil Recovery: from Fundamentals to Bench-Scale Demonstrations in Canadian Oil Sands Extraction
DownloadSpring 2020
Interfacial properties at the oil-water interface are of key importance to various operations in the petroleum industry, especially in the aqueous-based heavy oil recovery process. However, different operation stages often require different interfacial properties, which could be conflicted with...

Colloid Science of Sand Remediation: A Study Motivated by the Non-Aqueous Extraction of Bitumen from Oil Sands
DownloadFall 2014
The current water-based method of bitumen extraction requires withdrawal of fresh water from the Athabasca River — a practice which leads to the continual buildup of tailings ponds and other environmental concerns. As Alberta’s bitumen production is expected to more than double by 2020, there is...

The non-aqueous extraction process involves dilution of mined oil sand with an organic solvent (the “diluent”), followed by separation of unwanted materials (clays, silica sand, connate water, etc.) from the diluted bitumen. The main focus of this research is on the removal of fines solids from...
