Nice, simplified infographic from NPR about the production of Tar Sands.
The oil product extracted from Canada’s tar sands isn’t like conventional crude. Known as bitumen, it’s sticky and so thick, it can’t flow down a pipeline without extensive processing. There are two methods for getting bitumen out of the ground and turning it into usable products. Both are complex, energy-intensive and expensive processes - but high oil prices are finally making tar sands profitable.
