Oil production in the Kurdish region of Iraq remains unaffected by violence and exports are expected to rise, UPI quoted the Kurdish government as saying Saturday. A number of oil companies operating in the area, from Genel Energy to U.S. major Chevron, have pulled non-essential staff out of the area as a security precaution. So far, few companies have experienced significant declines in oil production as a result of the violence posed by Islamic extremist militants.
