Iran digs up ‘tens of billions’ in gas wealth as US energy showdown heats up

Iran has discovered a new gas field in southern Fars province containing more than 7.5 trillion cubic feet of gas, with associated gas condensate that Oil Minister Mohsen Paknejad said had brought “tens of billions of dollars of new wealth” to the country, as Tehran faces mounting US pressure over its energy trade.

Paknejad said on Sunday that about 5.7 trillion cubic feet of the gas could be recovered, based on an estimated recovery rate of 73%. The recoverable volume is equivalent to one block of Iran’s giant South Pars gas field and could supply gas for 15 years, he said, according to Iranian state media.

The discovery comes as Iran’s energy sector faces a more difficult operating environment. Parts of its oil and gas infrastructure have been damaged during the conflict with Israel and the United States, while Washington is preparing further economic measures aimed at tightening pressure on Tehran and countries and entities doing business with it.

The find gives Iran another potentially significant energy resource even as sanctions, infrastructure damage and uncertainty around the Strait of Hormuz complicate its ability to develop and monetise its hydrocarbon reserves.

A gas find with a valuable by-product

Paknejad said the newly discovered gas is “sweet”, meaning it requires less processing and could reduce development and operating costs.

The field also contains gas condensate, a valuable liquid hydrocarbon produced alongside natural gas. Paknejad directly linked the condensate to the scale of the economic opportunity from the discovery.

“In addition to this volume of gas, there is also a volume of gas condensate that has brought tens of billions of dollars of new wealth to the country,” Paknejad said.

The minister's comments refer to the wealth generated by the condensate; they do not amount to an independent valuation of the newly discovered gas reserves.

The scale of the gas find is significant against Iran’s existing production. The country had estimated pre-war gas output at around 650 million cubic metres per day, or roughly 8.4 trillion cubic feet annually, and has been working to restore capacity lost after damage to energy infrastructure.

The discovery will not immediately translate into additional gas supply. Developing an underground resource requires investment, production facilities and infrastructure, all of which become more challenging under sanctions and amid continuing regional tensions.

That challenge is already visible at South Pars, Iran’s main gas-producing complex.

Pars Oil and Gas Company chief Touraj Dehghani said on Saturday that production capacity at the Phase 14 refinery had recovered by about 70% after it was damaged during the “12-day war”. Three damaged production trains were restored in less than 10 days, while the remaining damaged train is expected to return to production by the end of the Iranian calendar year.

Dehghani said the third and fifth South Pars refineries, which sustained the heaviest damage among the affected facilities, were also being rebuilt. Initial estimates had put full reconstruction at three years, but the company now aims to complete the overall work within two years.

Why the discovery matters as Hormuz becomes a pressure point

The timing of the discovery matters because energy has become central to the confrontation between Iran and Washington.

US President Donald Trump has announced what he calls an “Economic D-Day” campaign against Tehran and said Washington has “very draconian sanctions” available. US Treasury Secretary Scott Bessent has separately warned of what he called the “toughest sanctions in history” and urged allies to join Washington in isolating Iran.

The pressure comes as Iran has threatened to halt oil exports from the Gulf if the economic confrontation continues, putting the Strait of Hormuz at the centre of the dispute.

The waterway is one of the world's most important energy corridors, carrying large volumes of oil and gas shipments. Any disruption or prolonged uncertainty around its use can therefore affect not only Iran's ability to export energy but also global markets.

That gives the new discovery a significance beyond the size of its reserves. Iran already holds some of the world's largest oil and gas resources, but sanctions and geopolitical tensions have repeatedly constrained its ability to turn those reserves into export revenue.

For Tehran, the immediate prize is therefore not simply finding more gas. It is developing the resource, restoring damaged production capacity and finding ways to get its energy to customers despite mounting pressure from Washington.

The gas is underground. Turning it into the “new wealth” Paknejad describes will depend on whether Iran can get it out — and get it to market.
