In an entirely unrelated matter but on a subject of interest to me the price of oil has dropped to $8 a barrel, Canadian oil that is. Specifically I'm referring to bitumen, the tar sands oil that is traded on the Alberta Exchange. Friday it closed at $8.35. Bitumen is cheaper than most other types of crude, because it has to be diluted with more-expensive lighter petroleum, and then transported thousands of miles from Alberta to refineries on the Gulf coast. Since most of the spending for bitumen extraction comes up front, and thus is a sunk cost, production will continue and grow. Canada will need more pipeline capacity to transport bitumen out of Alberta by 2019 so pressure to build the Keystone pipeline will not abate.
