Chavez is screwing up my oil/refinery play! He is selling the CITGO refineries:

BARQUISIMETO, Venezuela -- President Hugo Chavez announced last week that Venezuela hopes to gradually sell off its refineries in the United States and build a new network of refineries in Latin America as part of a plan to offer his allies in the region a stable oil supply.

If he sells these off, why they may turn and be more productive recuding the cost of the refined petrolium!
Trying to go independent and shoring up exploration with Chinese companies who don't have too much experience should be interesting to take advantage of their reservers as Chavez tries to subvert US policy.
