A fire on the SPD14D platform at Iran's South Pars gas field has been contained, Iranian officials said on Tuesday, after staff were evacuated from the offshore installation. The deputy oil minister said the situation was fully under control, and the cause remained under investigation.

The semi-official Fars news agency, cited by Reuters, reported that a gas leak or an operational incident were among the possible causes. The affected platform produces 14.5 million cubic metres of gas a day, against total output of about 700 million cubic metres a day from the field as a whole.

Why South Pars matters

South Pars is the Iranian side of the world's largest offshore natural gas field, shared with Qatar, which calls its portion the North Dome. The reservoir holds an estimated 1,800 trillion cubic feet of usable gas, enough to supply the world's needs for about 13 years, according to figures cited by Reuters.

Iran produced 276 billion cubic metres of gas in 2024, of which 94 percent was consumed at home, according to Gas Exporting Countries Forum data. That makes any disruption at South Pars a domestic energy issue first, but Iraq is exposed too: Iran halted gas flows to Iraq during the March fighting, and Iraq relies on Iran for between a third and 40 percent of its gas and power needs.

The field has been hit before. Israeli air strikes in March 2026 damaged several South Pars phases and halted output at two refineries, and officials later said about 40 percent of capacity had been restored. No casualties were reported in Tuesday's fire, and nothing in the official reports suggested the blaze was caused by an attack. Read the full reports at Reuters and Global Event Monitor.
