Despite international sanctions, Iran produced 8.4 trillion cubic feet (Tcf) of dry natural gas in 2019, making the country the world’s third-largest dry natural gas producer after the United States and Russia. Natural gas production in Iran has grown steadily over the past two decades despite sanctions that affected Iran’s energy exports, financial transactions, and imports of certain technologies. Iran’s domestic natural gas demand, which the sanctions do not affect, has been the main driver of Iran’s natural gas production growth.
