The South Pars and North Dome field is a natural gas condensate field located in the Persian Gulf. It is the world’s largest gas field, shared between Iran and Qatar.

According to the International Energy Agency, the field holds an estimated 50.97 trillion cubic meters (1800 trillion cubic feet) of in-situ gas and some 50 billion barrels of condensates.

This gas field covers an area of 9700 square kilometers, of which 3700 square kilometers (South Pars) is in Iranian territorial waters and 6000 square kilometers (North Dome) is in Qatari territorial waters.
According to IEA, the combined structure is the world’s largest gas field.

With in place volumes equivalent to 360 billion barrels of oil (310 billion barrel of oil equivalent of gas and 50 billion bbl of condensate) the field is the world’s biggest conventional hydrocarbon accumulation even bigger than Ghawar oil field, which has 170 billion barrels of original oil in place.

The field recoverable gas reserve is equivalent to some 215 billion barrel of oil and it also holds about 16 billion barrels of recoverable condensate corresponding of about 230 billion barrel of oil equivalent recoverable hydrocarbons.

The gas recovery factor of the field is about 70%, corresponding of about 36 000 km3 of total recoverable gas reserves which stands for about 19% of world recoverable gas reserves.

The estimates for the Iranian section are 500 tcf (14.2 tcm) of gas in place and around 360 tcf (10.1 tcm) of recoverable gas which stands for 36% of Iran’s total proven gas reserves and 5.6% of the worlds proven gas reserves.

The estimates for the Qatari section are 900 tcf (25.5 tcm) of recoverable gas which stands for almost 99% of Qatar’s total proven gas reserves and 14% of the worlds proven gas reserves.
