Iraqi engineers have fixed most of the damage caused by a sabotage attack earlier this month on the main pipeline that carries Iraqi oil to Turkey, but the country is still depending on a network of substitute lines to export crude, an official with the North Oil Co. said Monday. The official said 75 percent of the work has been done but few more days are needed for the 40-inch pipeline to be ready for exports to the Turkish port of Ceyhan. The pumping rate is still down to 250,000 barrels a day from the normal average of 400,000 barrels, the official said on condition of anonymity. Exports will go back to normal when the line is fixed, he said.
