New study suggests reported PAH emissions in oil sands region greatly underestimated

Green Car Congress

Results from a new modeling assessment of contamination in the Athabasca Oil Sands Region (AOSR) suggest that officially reported emissions of polycyclic aromatic hydrocarbons (PAHs) in that region have been greatly underestimated. Accounting for evaporative emissions (e.g., —Parajulee and Wania. Source: Parajulee and Wania.

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.

Transcanada restarts Keystone oil sands pipeline operations

Green Car Congress

TransCanada Corporation said that its 590,000 barrel-per-day (bpd) capacity Keystone Pipeline system resumed transporting oil sands crude on Sunday, 5 June, after a shutdown 29 May following an above-ground spill at a pump station in Kansas involving less than 10 barrels of oil. The tar sands are estimated (e.g.,

Examples of emerging oil sands related technologies and trade-offs. The paper is an examination of how various choices about the scale of the life cycle analysis applied to oil sands (i.e., The source material is neither oil nor tar but bitumen, but is most generally described as an example of ultraheavy oil.”.

CFR Report Says Energy Security and Climate Change Concerns With Oil Sands Can be Reconciled

Green Car Congress

Oil sands supply chain. A new report from the Council on Foreign Relations (CFR)— The Canadian Oil Sands: Energy Security vs Climate Change — claims that prudent greenhouse gas regulations can limit emissions from Canadian oil sands while still enabling robust development of the energy resource.

IEA: global map of oil refining and trade to be redrawn over next 5 years

Green Car Congress

Profound shifts in the regional distribution of oil demand and supply growth will redefine the refining industry and transform global oil trade over the next five years, according to the annual Medium-Term Oil Market Report (MTOMR) released by the International Energy Agency (IEA). The oil market is at a crossroads.
