Reverse Flow!

“For the first time, crude oil from Alberta, Canada, reached as far south as the giant Cushing pipeline hub in Oklahoma,” reports Chris Mayer. It did so on pipelines that for decades carried oil in the opposite direction. The Canadian oil sands are beginning to produce so much oil that pipeline managers are making plans to reverse the flow of domestic pipelines permanently.
And about a month ago, Canadian crude traveled all the way down to Texas -- the world’s largest cluster of refineries and the traditional “front door” for much of the U.S.’s oil supplies.
