The South Pars gas field (called the North Dome on the Qatari side) is by far the world's largest independent gas reservoir, located on the Iran-Qatar border in the Persian Gulf, about 100 km off the southern coast of Iran.
The field covers an area of 9,700 square kilometers of which 3,700 square kilometers belong to Iran. The in-situ gas reserves of this part of the field are estimated at 14.2 trillion cubic meters, along with 18 billion barrels of gas condensate and 7.5 billion barrels of crude oil in the field’s oil layer, which accounts for roughly 8% of the world and 47% of Iran’s total discovered gas reserves. The field plays a unique role in the national economy of the country.
Due to its size, development of the field has been on the agenda of the National Iranian Oil Company (NIOC) in different phases in accordance with the five-year economic, social and cultural development plans of the Islamic Republic of Iran and with the aim of meeting the growing demand for natural gas in the industrial units and power plants, domestic/commercial units, petrochemical complexes and injection into oil fields to protect reservoirs, as well as export of natural gas, gas condensate, liquefied petroleum gas and sulfur.
Development of the South Pars field and construction of refineries, gas transmission lines and infrastructure required in the South Pars Special Zone have earned the country tens of billions of dollars in gas sales and exports of by-products. In addition to environmental benefits, the use of clean natural gas energy as an alternative to nearly 2.6 million barrels per day of liquid fuel has been a driving force for the development of downstream industries and petrochemical complexes, generation of thousands of stable jobs and increasing the capacity of builders, consultants and contractors and maximum use of domestic capabilities.
