Spring 2019
The ionospheric Alfvén resonator (IAR) is an area of space that, due to sharp Alfvén speed gradients, has the ability to trap electromagnetic plasma wave energy, where it bounces in the Alfvén mode between near-Earth space and the lower ionosphere. Here we present research that, by comparing...

Lightning is widely acknowledged as a major cause of wildland fires in Canada. On average, 250,000 cloud-to-ground lightning strikes occur in Alberta every year. Lightning-caused wildland fires in remote areas have considerably larger suppression costs and a much greater chance of escaping...

Fall 2011
One of the major issues in the current oil sands waste management techniques is a lack of a direct linkage between the long-term mine plans and the quantity of the tailings produced downstream. This research is focused on developing a linkage between oil sands long-term mine plans and the final...

The mining of oil sands ore and extraction of bitumen produces aqueous slurries containing bitumen, coarse sand and fine clays. The performance of key process units is highly dependent on the rheology of “carrier fluid”, which is comprised of the fine solids and water. Although viscosity is...

The focus of the research presented here was to directly measure actual evaporation rates from a tailings surface using a micrometeorological technique known as the eddy covariance method. Depending on the results, it would be determined whether current drying models need to be calibrated with...

Methane Production and Emission Mitigation in Oil Sands Tailings Concurrent with Hydrocarbon Degradation under Nitrogen Limited Conditions
DownloadFall 2020
Alberta’s oil sands generate large volumes of tailings from bitumen ore processing. These tailings ponds produce biogenic methane, which can be measured across 60-80% of the tailings surface. Based on current surface area data and emissions studies, tailings ponds could account for 8% of Canada’s...

Spring 2010
Molecular dynamics simulation and density functional theory were applied to calculate heats of immersion (ΔHimm) of n-heptane, toluene, pyridine and water on two model sand surfaces and two model clay surfaces. Our results indicated that water showed the highest ΔHimm for the model clay surfaces...

Morphological Effects of Water Soluble Polymer Flocculants Synthesized by Controlled Reversible-Deactivation Radical Polymerization for Treatment of Mature Fine Tailings
DownloadFall 2020
The bitumen reserves in Northern Alberta are a valuable asset, but extracting bitumen from oil sands via the Clark hot water process produces undesirable waste tailings. These tailings are transported to tailings ponds where the sand and clay particles are left to settle slowly, creating a...

Spring 2018
Certain areas of oil sands in Canada are mined and processed for bitumen production using hot water processes that produce a slurry waste, referred to as tailings. Sand particles in tailings quickly settle and produce mature fine tailings (MFT), which are stored in large tailing ponds. Currently,...

Near-Wellbore Salinity Effect on Sand Control Plugging by Fines Migration in Steam-Assisted Gravity Drainage Producer Wells
DownloadFall 2023
Sand control screens are necessary for steam-assisted gravity drainage (SAGD) wells drilled into oil sands to prevent sand production. However, the accumulation of mobilized fine particles near the wellbore can result in screen plugging, adversely affecting the well's flow performance. This...
