It is thick and sticky like butter. it is a mixture of water, sand, clay, slit, unrecovered hydrocarbons and many other. So extract oil from it is pretty hard.

To extract 1 barrel oil from the tar sand it requires 2-4.5 gallons of fresh water.The used water is highly toxic for the the living creatures.
