Not really.
Take Iran. They subsidize their gas something fierce.
They are having a hard time even at 120 a barrel to meet all the demands from the people. Iran has no real export other than oil. They import most of their gas.
Venizuala (wow I butchered that), has made so many cash related commitments they HAVE to have 120 a barrel just to meet the existing commitments. They have purchased a LOT of power in south america. If the price stays at under 90 a barrel for more than 6 months they are screwed.
Very few middle east countries have any other type of income other than oil. So when the price went up, the governments just started giving stuff away to the people to make them happy. When the price goes down and the governments can't keep giving stuff away, that is when the people get angry.
As long as oil stays above 60 dollars a barrel it is break even point for exploration drilling in the US (2006 figure). There will be a slow down, but it won't be a stoppage like you saw in the 70's when texas went bust and their economy crashed.
