Spring 2012
Tailing ponds in Northern Alberta has covered an area of 170 km2. Directive 074 issued in 2009 set stringent criteria for tailings reclamation. Freeze-thaw dewatering is one of the most promising approaches for dewatering MFT as one cycle of freeze-thaw can release up to 50% pore water. In this...

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...

Fall 2017
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...

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...

Reclamation of Unconventional Oil Processed Water through the Adsorption of Naphthenic Acids by Carbon Xerogel
DownloadFall 2017
This study examines the use of carbon xerogel (CX) material for the adsorption of naphthenic acids (NAs). The adsorption of NAs is crucial for the reclamation of unconventional oil processed water, more specifically Alberta’s oil sands process-affected water (OSPW). CX material is synthesized at...

Removal of Organic and Inorganic Contaminants from Oil Sands Tailings using Carbon Based Adsorbents and Native Sediment
DownloadFall 2013
The extraction and refinement of oil sands bitumen produces substantial quantities of liquid tailings and solid coke. Tailings contain metals and naphthenic acids, which require remediation before mine closure. Adsorption is a potential remediation technique which may reuse stockpiled petroleum...

Turbidity Mitigation in an Oil Sands End Pit Lake through pH Reduction and Fresh Water Addition
DownloadFall 2016
The remediation of oil sands wastes such as fluid fine tailings (FFT) and oil sands process-affected water (OSPW) are of increasing concern in the oil sands industry. End pit lakes are one remediation option currently being researched at commercial scale in Base Mine Lake (BML) operated by...
