Erland, Broghan

To combat global warming, Canada has committed to reducing greenhouse gases (GHGs) 40-45% below 2005 emission levels by 2025. Monitoring emissions and deriving accurate inventories are essential to reaching these goals. GHGs can be measured at a small scale, often using ground measurements which...

Miles, Sarah, M

Current development of Alberta’s oil sands region requires large volumes of water, leading to an abundance of oil sands process affected water (OSPW). OSPW contains naphthenic acid fraction compounds (NAFCs) which have been found to contribute extensively to OSPW toxicity. Degradation of this...

The bitumen production from oil sands surface-mining operations produces large volumes of mineral wastes called tailings. Characterization of the oil sands tailings is of importance to monitor their state for trafficability and reclamation issues, to assess the tailings operation performance, and...

The extraction of bitumen from oil sands in Alberta, Canada, leads to the creation of tailings that are contained in lake-sized ponds under zero discharge policy. Stratification of tailings over time leads to the formation of mature fine tailings (MFT), an oil based emulsion containing residual...

Oil sands fluid fine tailings (FFT) are comprised of sand, silt, clay, residual organics, salt, trace metals and process-affected water (OSPW). In order to accommodate and remediate large amounts of FFT, a full-scale demonstration pit lake, where FFT was capped with a mixture of OSPW and fresh...

Solvent based extraction has the potential to supplant the current hot water based extraction process as the industry standard method for recovering bitumen from mined oil sand. It has the potential for higher bitumen recovery that is less sensitive to the grade of oil sand ore being processed....
