Summary
As of 2015, 36% of total U.S. crude imports come from Canada.
Canada is a large exporter of low API grade crude referred to as heavy crude oil, most of which comes from Canada’s bituminous Oil Sands deposits.
To deal with the lack of fluid-flow of Canadian heavy oil and bitumen, some oil production is partially refined to produce synthetic crude, which creates more fluidity.
How is it that Canada could be dependent on U.S. oil production? As of 2015, 36% of total U.S. crude imports come from Canada. As Canada continues to exports over 3 million barrels per day of oil to the U.S., what direct role does the U.S. have in allowing Canadian oil to flow southward?
