The offshore platform of Phase 15, consisting of 11 wells, pumps sour gas into onshore refineries through an undersea pipeline.
The sour gas extracted from phases 15 and 16 is treated in an exclusive sweetening unit before being injected into the country’s national gas network.
The South Pars gas field, whose development has been divided into 28 phases, is located in the Persian Gulf straddling the maritime border between Iran and Qatar. It is estimated that the Iranian section of the field contains 14 trillion cubic meters of gas and 18 billion barrels of condensates in place.
South Pars is part of a wider gas field that is shared with Qatar. The larger field covers an area of 9,700 square kilometers, 3,700 square kilometers of which are in Iran's territorial waters (South Pars) in the Persian Gulf. The remaining 6,000 square kilometers, referred to as the North Dome, are in Qatar's territorial waters.
