Oil prices rising? Chemistry project. Help?

Could anyone please provide me a link where I can find a graph showing the rising prices of petroleum oil? Preferably global?

Try the link below. There are many sources of oil information, I used ';price of crude oil graph'; as my search criteria. Also, please realize there is no ';global'; price for oil, although you can see some averages. It depends on the type of oil (how easy it is to refine, how much sulfur, etc.) and where it is produced and /or where it is delivered to the market.
