Spring 2014
In bitumen recovery from oil sands, a percentage of the bitumen is lost to tailings. The effect of fugitive bitumen on fines settling and consolidation in tailings ponds remains controversial. In the current study, the settling performance of mature fine tailings (MFT) in response to flocculant...

The formation of stable water-in-oil emulsions during oil sands extraction process causes a number of operational issues, such as equipment corrosion, storage and transportation problems. One common method for emulsion breakup in industry is to use chemical demulsifiers. The chemical demulsifiers...

Expression of Major and Trace Element Signatures of the Frasnian Duvernay Formation within a Sea Level Context: insights into the processes that control mudstone composition, paleoredox conditions and organic matter enrichment
DownloadSpring 2016
This study evaluates the effects of sea level on redox conditions, shale composition and sediment provenance in the Late Devonian (Frasnian) Duvernay Formation of the Western Canada Sedimentary Basin (WCSB) of Alberta, Canada, an organic-rich ‘black’ shale localized between the reefs and...

Spring 2011
Extraction of hydrocarbons from an Athabasca oil sand slurry were conducted using supercritical carbon dioxide (SC-CO2). The oil sand was slurried to a 1:1 ratio with water and experiments were conducted using a laboratory-scale batch supercritical fluid extraction (SFE) system. Preliminary tests...

Extraction of Hydrocarbons from Bitumen and Bitumen-containing Process and Process Waste Streams using Supercritical Carbon Dioxide
DownloadSpring 2019
Extractions of hydrocarbons from bitumen and bitumen-containing process and process waste streams generated from surface mined oil sands were conducted using supercritical carbon dioxide (SC-CO2). Dynamic extractions were performed on a bench-scale batch supercritical fluid extraction (SFE)...

Heavy Oil/Bitumen Recovery by Alternate Injection of Steam and Solvent (Hydrocarbon and CO2) in Fractured Carbonates and Oilsands
DownloadFall 2013
The world energy demand is constantly increasing and fossil fuels are still by far the main energy resource that supplies the world energy consumption market, therefore increasing oil recovery from all types of reservoirs is an important matter. The burning of fossil fuels for energy purposes, on...

High-Float Emulsion Residue: A New Rheological Model Based on the Existence of a Yield Stress
DownloadFall 2016
“High-float” (HF) emulsions are dispersions of micron-sized bitumen droplets in water, with a special type of anionic surfactant functioning as stabilizer. By allowing the water to evaporate from an HF emulsion, what remains is called a “high-float emulsion residue.” Although indistinguishable in...

The rheological properties of heavy oil and bitumen depend on factors such as temperature, pressure, diluent type and diluent composition, as well as sample shear and thermal histories and shear conditions during measurements. Each of these factors can affect the value of apparent viscosity...

The oil sands industry in Alberta, Canada has been thriving for over five decades, and this multi-million-year-old resource has fueled rapid economic growth in Alberta. However, the oil sands industry has left behind tons of oil sands tailings and oil sands process-affected water (OSPW), and the...
