Canada isn't on this graph, but I think would be somewhere near the top left, in tier 1 or 2. High-cost, low value tar, but not providing a lot of net fiscal contribution, due to low taxes and high subsidies, relative to the large non-oil economy.
A sovereign Alberta would be in the same vertical position, but waaay over to the right of Saudi. The Saudis have been diversifying away from oil for 25+ years. AB has been trying to undiversify for 50.
