    Two tons / barrel not not 60 would have to be moved all that distance. That might be a net energy-gainer.

    But it's still easier to pump 300 pounds of crude than 4,000 pounds of sand, so I'd expect these companies to pre-process the sand at the mine site if it were at all possible.

      From what I understand, some companies are starting (maybe it's established now?) to use steam-based extraction methods that loosen the oil enough that it's brought to the surface, sans sand. The idea, as you note, is to ship a product that can be refined by anyone. So, if it matters, the excessive energy usage - above and beyond the norm - is occurring in Western Canada.
