Joel Wing measures the Iraqi oil pipelines:

Weather, bottlenecks, and attacks upon pipelines account for the monthly fluctuations Iraq has experienced in the last few years. Otherwise the country is operating at just about capacity. That's why output has hardly changed in the last 17 months. Its aging infrastructure cannot handle much more. Luckily prices for Iraqi crude have been increasing until May, which has meant a steady income for the government. Even if prices decline more in coming months they will still probably be above the budget's mark, which will mean Baghdad will be able to finance its operations. That will give it enough time and money to hold it over until the international companies get to work with the new oil deals, and hopefully boost production. How much that will be is the real question facing Iraq's petroleum industry.
