This man: http://en.wikipedia.org/wiki/Benjamin_Silliman,_Jr. wrote a report in 1855 which led to the financing for the Drake oil well.
The price of oil which prompted said investment in 1855?
$20/barrel
In what is now the Ukraine, at much the same time, oil was harvested by hand and sold for $140/ton - roughly equal to $20/barrel.
From 1880 to 1970, the price of oil was roughly $1/barrel.
