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)...

Fall 2010
This study investigates the extraction of hydrocarbons from oil sand using supercritical carbon dioxide (SC CO2). Experiments were carried out on three different types of oil sands. After some preliminary experiments, the feasibility of extracting hydrocarbons from oil sands by SC CO2 was...

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...

Spring 2019
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...

Investigation of Pavement Management Practices and Pavement Material Performance in Alberta, Canada
DownloadFall 2018
Roadways are one of the most important pieces of public infrastructure in any municipality, province, or country. Roads connect economic corridors encouraging trade, provide citizens with the option to travel, and remain a necessity for all people to access work and the majority of the main...

Fall 2023
Non-aqueous extraction (NAE) process was explored as an alternative to the Clark hot water extraction process (CHWE) to recover bitumen from Alberta oil sands. The upshot of the NAE process is that it eliminates the latter’s environmental issues concerning high fresh water and energy...

Laboratory Rock Strength Measurements of Saturated Carbonates: Implications for the Grosmont Formation
DownloadFall 2018
The Devonian Grosmont formation, located in Alberta, contains vast resources totaling approximately 405 billion barrels of crude bitumen-in-place. The highly viscous bitumen is by definition less than 10° API gravity, remaining immobile at Grosmont formation in-situ temperatures. In the oil and...
