The South Pars/North Dome field is a natural-gas condensate field located in the Persian Gulf. It is by far the world's largest natural gas field, with ownership of the field shared between Iran and Qatar. According to the International Energy Agency (IEA), the field holds an estimated 1,800 trillion cubic feet (5.1×1013 cubic metres) of in-situ natural gas and some 50 billion barrels (7.9 billion cubic metres) of natural gas condensates. On the list of natural gas fields it has almost as much recoverable reserves as all the other fields combined. It has significant geostrategic influence.
This gas field covers an area of 9,700 square kilometres (3,700 sq mi), of which 3,700 square kilometres (1,400 sq mi) (South Pars) is in Iranian territorial waters and 6,000 square kilometres (2,300 sq mi) (North Dome) is in Qatari territorial waters.
As of early 2026, before the beginning of the US-Iran war, Qatar has produced approximately 18.5 billion cubic feet per day from the field, accounting for around 80% of Qatari government revenues, while daily production on the Iranian side was estimated to be around only 2 billion cubic feet. Iran's inefficient exploitation of the shared gas field is often attributed to Western sanctions, isolation and mismanagement. These have also caused the Iranian government to lag behind on pressurization efforts on their side of the field, which causes more gas to migrate to the Qatari side of the field.
