What has been the annual average price per Barrel of Crude Oil over the last 30 yrs?

Yearly average and high and low price each year would be nice.What has been the annual average price per Barrel of Crude Oil over the last 30 yrs?
i recently read an article in the local paper that had a chart showing the price of crude over the past 25 years. i believe it was 14$ a barrel. in the 1990s the price stayed in the low teens and even dropped to 10$ a barrel at one time. only in 2001 did crude start to go up in the 30s. and it really didnt spike until after the 2004 elections where it went to 55$ a barrel. i hear people say all of the time that politics and th price of crude are not related whatsoever!! well the congressional elections are coming and the price of crude and gas is dropping.(TEMPORARILY). look for it to spike once again by the first of the year, especially if the republicans dont lose the house or senate.
