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. Earlier post.). —Nduagu & Gates.

Understanding the variability of GHG life cycle studies of oil sands production

Green Car Congress

Full-fuel-cycle GHG emissions estimates for reformulated gasoline pathways by LCA study. He found that the variation in oil sands GHG estimates is due to a variety of causes. These include oil sands, enhanced oil recovery, coal-to-liquids and gas-to-liquids synthetic fuels, and oil shale.

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.,

EIA projects world energy use to increase 53% by 2035; oil sands/bitumen and biofuels account for 70% of the increase in unconventional liquid fuels

Green Car Congress

Unconventional liquids become increasingly important in the total supply of liquid fuels, according to IEO2011. World oil prices remain high in the IEO2011 Reference case, but oil consumption continues to grow; both conventional and unconventional liquid supplies are used to meet rising demand.

Researchers Suggest That Although CCS and Other Technologies Could Reduce Oil Sands GHG Emissions to Near Zero, That Strategy May Not Make Sense

Green Car Congress

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.”.

Univ. of Alberta and Helmholtz Association Partner to Develop Oil Sands Technologies to Address Environmental Issues

Green Car Congress

The goal of the initiative is to transform oil sands production processes by developing technologies that address sustainability challenges. The University of Alberta, recognized as a global leader in oil sands research, will work with the Helmholtz Association, a collection of 16 science and technology centers across Germany.
