Considering the vast area of this gas field, its development was planned in several phases. The aim of developing of South Pars is ‎supplying the increasing demand for the natural gas required for the country’s domestic ‎consumption, injecting gas into the oil fields, and exporting gas and condensates. Supplying gas as ‎feedstock for the petrochemical industry is on the agenda of the National Iranian Oil Company ‎‎(NIOC) .‎

The field is already being developed in different phases; so far ‎‏14‏‎ gas processing plants have been ‎planned. With regards to the reservoir’s capacity, the development phases can increase to ‎‏28‏‎ ‎phases or even more to further develop the giant gas field. Meanwhile, ‎‏15‏‎ huge petrochemical complexes and a wide ‎range of downstream petrochemical units, different related industries, semi-heavy industries, ‎marine industries and considerable number of service related facilities are predicted in this zone. ‎

South Pars Development Plan; Phase ‎‏1‏

The contract for the development of this phase was awarded to the Iranian ‎company Petro Pars as a general contractor in Feburary ‎‏1998‏‎. Investment value ‎on this project is ‎‏USD910‏‎ milion on buyback basis. ‎

After completion of all offshore and onshore facilities, operation of its first unit ‎has been started in April ‎‏2004‏‎.It took some more months for this phase to be fully operational in November ‎‏2004‏‎.

South Pars Development Plan; Phase ‎ ‏3‏ & ‏2

The development of these two phases were awarded to the consortium of ‎TOTAL of France, Petronas of Malaysia, and Gasprom of Russia with the ‎management of Total South Pars (TSP) on September ‎‏1997‏‎. Total investment value of ‎these two phases is more than USD‎‏2‏‎ billion on buyback basis. This project was ‎inaugurated in February ‎‏2003‏‎.

South Pars Development Plan; Phase ‎‏5‏ & 4‏‎ ‎

Development of this project started in August ‎‏2000‏‎ by investing about USD‎‏2‏‎ ‎billionon buyback contract by the Italian Agip Company (a subsidiary of ENI of ‎Italy) and Iranian company Petro Pars.‎

This project was officially inaugurated in April ‎‏23‏‎, ‎‏2005‏‎.‎

South Pars Development Plan; Phase ‎‏ 8‏ &‏ 7 ‏,6‏‎ ‎

Development of the phases which aimed at injecting sour gas into oil wells at ‎Aghajari oil field, was started in February ‎‏2004‏‎ by investing about USD ‎‏1,964‏‎ billion on buyback contract. The project was awarded to a consortium comprising of t he Industrial Development & Renovation Organization (IDRO) , Petro Pars of Iran, Toyo and JGC of Japan, and South Korea’s Daelim . The phases started production in ‎‏2008‏‎.‎

South Pars Development Plan; Phase ‎‏ 10& ‏9 ‏

The contracts for phases ‎‏9‏‎ and ‎‏10‏‎ were signed in September ‎‏2002‏‎ with ‎a consortium of GS, Oil Industries Engineering and Construction (OIEC) ‎ of Iran, and Iranian Offshore Engineering and Construction ‎Company(IOEC) . The investment value of these two phases were more than USD ‎‏2‏‎ billion.‎

Both phases started production in 2009, and produce 5.56 million cmd of gas.

South Pars Development Plan; Phase ‎‏11‏

Development of South Pars phase ‎‏11‏‎ aims at supplying sour gas for Iran ‎LNG Plant. This project is awarded through a buyback contract to the CNPC of China.‎

South Pars Development Plan; Phase ‎‏12‏

Development of South Pars phase ‎‏12‏‎ is designed to produce ‎‏78‏‎ million cubic meters of gas daily. Nearly ‎‏56‏‎ million cubic meters of produced gas will be feed to ‎NIOC LNG, and the sour gas will be injected to the oil fields.‎‏Rest of the production would be transferred for the country’s domestic consumption.

South Pars Development Plan; Phase ‎13

Development project for South Pars phase ‎‏13‏‎ is designed to supply ‎required sour gas for Iran LNG project.

South Pars Development Plan; Phase ‎‏14‏

Development project of this phase is under study.‎ The phase's production capacity is assessed at two billion cubic feet per day . A refinery would be constructed in this phase to produce 50 million cmd treated gas , 1 .1 million tons annually of liquid gas for export , 77 ,000 bd of condensates for export , and one million ton of Ethan annually .

South Pars Development Plan; Phase ‎‏16‏ & ‏15‏

Development of South Pars phases ‎‏15‏‎ and ‎‏16‏‎ are designed to produce ‎‏50‏‎ millions cubic meters of natural gas, ‎‏80,000‏‎ barrels of condensate, ‎‏400‏‎ tons ‎of Sulphur per day, and ‎‏1.05‏‎ million tons of LPG, and ‎‏1‏‎ million tons of ‎Ethan annually to be supplied to petrochemical plants.‎

South Pars gas Development Plan; Phase ‎‏18‏ & ‏17‏

Development of South Pars phases ‎‏17‏‎ and 18 are designed to produce ‎‏50‏‎ ‎million cubic meters of natural gas, ‎‏80,000‏‎ barrels of condensate, ‎‏400‏‎ tons of ‎Sulfur per day, and production of ‎‏one million tons of Ethan and ‎‏1.05‏‎ million tons ‎of LPG per year.‎

South Pars Development Plan; Phase 19 ‎‏

The production capacity of this phase is two billion cfd. A refinery also is planned to be constructed at this phase which would produce 50 million cmd of treated gas, 1.1 million tons of liquid gas annually, 77,000 bpd gas condensates, and one million ton of Ethan per year.

South Pars Development Plan; Phase 20 & 21

These two phases are planned to be awarded to domestic contractors through EPCCS contract. These phases aim to supply 50 million cmd of gas for domestic consumption, recycle one million ton of Ethan each year, recycle 1.05 million ton liquid gas per year, production of 75.000 bpd of treated sulfur, and recycle of 400 tons of sulfur per day.

South Pars Development Plan; Phase 22, 23 & 24

Total production capacity of these phases is two billion cfd. A refinery also is planned to be constructed at these phases which would produce 50 million cmd of treated gas, 1.1 million tons of liquid gas annually, 77,000 bpd gas condensates, and one million ton of Ethan per year.
