Researchers identify for first time individual naphthenic acids in oil sands process water

Green Car Congress

A team from the University of Plymouth (UK) and Environment Canada has identified, for the first time, individual soluble naphthenic acids (NA) in the process water resulting from the oil sands industry in Canada. A paper on their work is published in the ACS journal Environmental Science &a,p; Technology.

Oil sands GHG lifecycle study using operating data finds lower emitting oil sands cases outperform higher emitting conventional crude cases; a call for more sophisticated tools and reporting

Green Car Congress

Well-to-wheel (WTW) greenhouse gas emissions for in situ SAGD and surface mining pathways generated employing GHOST/TIAX/ GHGenius combination and comparison with SAGD, mining and conventional crude oil literature pathways (all results are on a HHV basis). 74% of WTW emissions in our oil sands pathways.

Ionic liquid-enhanced solvent extraction for oil sands bitumen shows high recovery rates, less water use and no tailing water

Green Car Congress

Researchers from Tianjin University and the National Engineering Research Centre for Distillation Technology, Tianjin, China, report on the use of an ionic liquid (IL) with low viscosity to enhance bitumen recovery from oil sands by solvent extraction while reducing adverse impacts in the ACS journal Energy & Fuels.

U Calgary study finds oil shale most energy intensive upgraded fuel followed by in-situ-produced bitumen from oil sands

Green Car Congress

A team at the University of Calgary (Canada) has compared the energy intensities and lifecycle GHG emissions of unconventional oils (oil sands and oil shale) alongside shale gas, coal, lignite, wood and conventional oil and gas. This is not the same as crude oil occurring naturally in shales, as in the Bakken.

Devon Energy obtains approval for third Jackfish oil sands project

Green Car Congress

US-based Devon Energy Corporation has received regulatory approval from the Alberta Energy Resources Conservation Board and Alberta Environment and Water to move forward with the company’s third oil sands project in Canada. Devon’s Jackfish projects are designed to utilize saline water rather than fresh water.

Study finds that native microbes biodegrade longer-chain hydrocarbons in oil sands tailings to methane; implications for management of tailings and GHG emissions from tailings ponds

Green Car Congress

Proposed anaerobic hydrocarbon biodegradation pathways in oil sands tailings. The researchers now report that higher molecular weight n -alkanes (C 14 , C 16 , and C 18 ) are also degraded under methanogenic conditions in oil sands tailings, albeit after a lengthy lag (180 days) before the onset of methanogenesis.
