The purpose of this report is to use a design of experiment (DOE) approach to examine the main factors affecting the determination of methylene blue index (MBI) values for oil sands samples. The methylene blue titration of clays has become a principle tool to assess extraction efficiency of oil...
Benign-by-Design: Synthesis of Engineered Silicon Nanoparticles and their Application to Oil Sands Water Contaminant RemediationDownload
Oil sands are naturally occurring mixtures of sand or clay, water, fine silts, and bitumen. The oil sands extraction process consumes large volumes of water (i.e., ca. 3 barrels of fresh water for every 1 barrel of oil). Following the extraction of bitumen from the oil sands, a tailings slurry...
The oil sands industry in Alberta produces large volumes of process-affected water (PAW), which is known to contain heavy metals and organic compounds (such as naphthenic acids, naphthalene, phenanthrene, pyrene, etc.) that are toxic and hazardous to the environment. The industry has an ongoing...
Isotopic and Geochemical Tracers for Fingerprinting Process-Affected Waters in the Oil Sands Industry: A Pilot StudyDownload
A pilot study was conducted by Alberta Innovates – Technology Futures during 2009 and 2010 to assess potential for labelling process-affected water from oil sands operations using a suite of isotopic and geochemical tracers, including inorganic and organic compounds in water. The study was...
A microcosm-based experiment was conducted to investigate the ability of community level physiological profiling (CLPP) to detect changes in an aquatic microbial community resulting from exposure to oil sands process affected water (OSPW). Detection of the microbial response was done by using...
Next Generation Sequencing of Protists as a Measure of Microbial Community in Oil Sands Tailings Ponds: Amplicon Versus Metagenomic ApproachesDownload
The Alberta oil sands provide a major benefit to the province as an economic driver. At the same time, their responsible exploitation, particularly in mitigating the environmental impact of oil extraction stands as a significant challenge to be addressed. One of the most contentious aspects is...
The Oil Sands Leadership Initiative (OSLI) is a collaboration of five progressive oil sands operators (ConocoPhillips Canada, Nexen Inc., Statoil Canada, Suncor Energy Inc. and Total E&P Canada), with the Government of Alberta participating as an observer, working to advance the development of...
BGC Engineering Inc. (BGC) conducted a review of existing tailings technologies for the Oil Sands Research and Information Network (OSRIN). Over the years, many technologies have been proposed and field tested but they have been rejected for lack of technical or economic feasibility. With no...
The accumulation of mature fine tailings (MFT) in tailings ponds with very slow natural consolidation rate has been a concern for decades. Previous studies and current practices for tailings consolidation focus on the addition of various inorganic and organic additives to reduce MFT production...
Report and Recommendations of the Task Force on Tree and Shrub Planting on Active Oil Sands Tailings DamsDownload
Dam safety concern over the planting of trees and woody shrubs is in conflict with progressive reclamation, which is also a desirable outcome for oil sands tailings dams. International dam safety practice commonly restricts trees and woody shrubs on the downstream slopes of dams to preclude...
