Correct but that is just an extension of the “Bakken” play. I am talking about its equivalent up through the Alberta Basin. It can be traced for hundreds of miles up to the north. I have seen outcrops of it in the spectacular Canadian Rockies near Banff. If you have never been to Banff/Lake Louise, it is well-worth the trip. It is Yellowstone on steroids minus all the wildlife wondering around.
I don’t claim it is equal on both sides.
