The effects of the Iraq insurgency

An Iraqi worker adjusts a control valve at the Daura oil refinery on November 5, 2009 in Baghdad, Iraq. Iraq and a grouping of U.S and European oil companies Exxon Mobil Corp and Royal Dutch Shell PLC signed a $50 billion contract today to develop the West Qurna oilfield, two days after the Iraqi South Oil Company signed a technical service contract with Britain's BP and China's CNPC to develop the Rumaila oilfield. The Iraqi government is trying to attract foreign investment, especially in the oil sector, in hopes of reviving its war-torn economy. Iraq has the third largest oil reserve in the world but it is producing way below its potential. (Photo by Muhannad Fala'ah/Getty Images)
