I'm not sure I understand what you're saying.
You realize that there is some profit derived by the refiner--why shouldn't it be in the U. S.? And, there's a pretty good transportation infrastructure centered around Oklahoma. Isn't that more centrally located than the Canadian field for distribution around the U. S.? And why build refineries up there if they exist here?
Now, if my assumptions are wrong, and the pipeline will cause some problems, tell me about it, and I'll reconsider my take on the situation.
There is nothing wrong with building new refriners, just south of the border is there. At least they would not be shutting down and running up price everytime a storm hits the gulf.
Whiting Refinery Modernization Project
http://www.bp.com/sectiongenericarticle.do?categoryId=9030203&contentId=7055766#7205736
Today, BP is investing several billion dollars in Northwest Indiana to modernize its Whiting Refinery for the processing of heavier crudes. The modernization is essential to the long-term viability of the refinery, and includes well over a billion dollars in environmental improvements.
The modernization
project will provide for greater energy security in the
Midwest, as conventional supplies of the lighter crudes
diminish, and are replaced by heavier crudes.
With this in mind, the project involves repositioning Whiting
to be able to run heavier sour crude oil. It involves a new
crude distillation unit, a 100kbd coker, world scale
hydrotreating and sulphur recovery, and improvements
