the country is under an extended period of U.S. sanctions. As of January 2012, Iran exports 22% of its oil to China, 14% to Japan, 13% to India, 10% to South Korea, 7% to Italy, 7% to Turkey, 6% to Spain and the remainder to France, Greece (& other European countries), Taiwan, Sri Lanka, South Africa. In 2020 exports of petrochemicals and petroleum products were worth almost $20 billion. Natural gas In addition to the natural gas associated with oil exploration and extraction, an estimated 62 percent of Iran's 32.3 trillion cubic meters of proven natural gas reserves in 2006 were located in independent natural gas fields, an amount second only to those of Russia. In 2006 annual production reached 105 billion cubic meters, with fastest growth occurring over the previous 15 years. In 2006 natural gas accounted for about 50 percent of domestic energy consumption, in part because domestic gas prices were heavily subsidized. Natural gas production will reach 700 million cubic meter/day by 2012 and 900 million cubic meter/day by 2015. Since 1979, infrastructure investment by Iranian and foreign oil firms has increased pipeline capacity to support the Iranian gas industry. Between 1979 and 2003, pipelines to transport natural gas to refineries and to domestic consumers increased from 2,000 kilometers to 12,000 kilometers. In the same period, natural gas distribution pipelines increased from 2,000 kilometers to 45,000 kilometers in response to growing domestic consumption. Gas processing plants are located at Ahvaz, Dalan, Kangan, and Marun, in a corridor along the northern Persian Gulf close to the major gas fields. South Pars, Iran's largest natural gas field, has received substantial foreign investment. With its output intended for both export and domestic consumption, South Pars is expected to reach full production in 2015. However, delays and lower production in the Iranian side due to sanctions is resulting in migration of gas to the Qatari part and a loss for Iran. The output of South Pars is the basis of the Pars Special Economic Energy Zone, a complex of petrochemical and natural gas processing plants and port facilities established in 1998 on the Persian Gulf south of Kangan. Iran is able to produce all the parts needed for its gas refineries. Iran is now the third country in the world to have developed gas to liquids (GTL) technology. In the 1980s, Iran began to replace oil, coal, charcoal, and other fossil-fuel
