Will name brainliest and award 20 ! what is the significance of the athabasca oil sands in canada? (dot jot format plz)

There are a number of facts about Oil Sands

There is so much of that heavy oil in the North. You might have to check this but it is the 6th largest oil pool in the "free" world.It is near the surface. Oil rigs are unnecessary. It is terribly difficult to separate. It requires 1 barrel of oil to get 2 barrels of usable oil in refined state. To compare it with West Texas Crude, 1 barrel of usable oil will refine 35 barrels of  West Texas Crude.It has become the backbone of Alberta's economy -- that and agriculture. Both are commodities. Both are tanking (price wise). Both will recover: the question is when.

I don't know what Dot Jot Format is.
