Infographics of South Pars Phases 12, 15 and 16

South Pars gas field is the largest gas reservoir in the world. The field is jointly owned by Iran and Qatar. Iran sits atop 14 tcm of gas and 18 billion barrels of gas condensate in its sector of South Pars. That makes up around 7.5% of total world gas reserves and nearly half of Iran's total gas reserves. According to planning by the Iranian Ministry of Petroleum, South Pars gas field is being developed in 24 phases for a final output of 800 mcm/d. Ten phases of South Pars had already become operational when President Hassan Rouhani took office in 2013. Over these years, Phases 12, 15 and 16 have become operational. Iran is currently recovering nearly 500 mcm/d of gas from this giant gas reservoir.

Hassan Rouhani, President of the Islamic Republic of Iran:

With full development of South Pars, Iran would be earning $100 billion a year in revenue. With gas production hike, it will be possible to export gas to neighboring and even non-neighboring countries and Iran's interaction with the world will grow.

Bijan Zangeneh, Minister of Petroleum:

Phase 12 is the largest project that has ever become operational in the history of Iran's petroleum industry. It shows that Iran's petroleum industry has reached self-reliance.

Phase 12:

Phase 12 of South Pars is equivalent to three standard phases with 600 bcm of gas in place, which makes up 5% of South Pars total reserves.
