Question: what is the difference between canadian crude index and western canadian select?
Answer: An important benchmark price in Canada is known as Western Canada Select (WCS). ... Since the oil in WCS is much heavier than WTI (which is a light oil), and further away from main markets, WCS is priced at a further discount to WTI. Other oil streams produced from the oil sands are also priced at a discount to WTI or WCS.
