In this Sept. 18, 2006 file photo, Venezuela's President Hugo Chavez, left, and Iran's President Mahmoud Ahmadinejad wave to the press after inaugurating an oil drill in San Tome, Venezuela. Following Tuesday s death of Hugo Chavez, Venezuela faces near-term political uncertainty that could bring further turmoil to its oil industry. The country s oil exports fell by nearly half during Chavez s 14 years as president and that kind of decline is not easily reversed. It will take years of investment to turn around the country s beleaguered oil sector. (AP Photo/Fernando Llano, File)
