How much of the world’s proven natural gas reserves is located in the Persian Gulf region?

The Persian Gulf region holds approximately one-third of the world’s estimated proven natural gas reserves.1

This significant concentration of resources is largely associated with the major oil fields found in the Arabian-Iranian basin, which underlies much of the region. Notably, the area contains the world’s largest nonassociated natural gas field—the supergiant North Field of offshore Qatar and South Pars of offshore Iran—which is estimated to contain more than 28 trillion cubic metres (1,000 trillion cubic feet) of reserves.2
