Iraq has immense oil and natural gas resources that could be rapidly expanded to more than double oil production by 2020 and for Iraq to become a major global oil supplier and natural gas exporter. However, realizing this potential will require overcoming challenges including improving energy infrastructure, developing the hydrocarbon sector governance, and coordinating major investments along the supply chain. Success would transform Iraq's economy and have significant impacts on global energy markets, but any delays in development would be costly to Iraq and could tighten international oil supplies and prices.
