From jet fuel to rubber ducks

Researchers broke down a typical barrel of Western Canadian Select (WCS), which is used as a benchmark to value Canadian heavy crude oil. One of the components of WCS is bitumen, a thick, molasses-like form of crude oil produced from the oil sands deposits in Alberta. Additional components include other oils, synthetic crude and diluents. Before usable products can be created using WCS, it must be refined to increase its quality.
