South Pars Shatters Its Own Record — Again — With 730 MCM/Day, Despite Strikes, Sanctions and Strike Damage

Iran’s South Pars gas field — the world’s largest, straddling the Persian Gulf border with Qatar — produced 730 million cubic meters of rich gas per day in February 2026, Oil Minister Mohsen Paknejad announced via his official account on X. The figure represents a new all-time high in the field’s history and the ninth production record set in the past two years, a streak that has seen daily output climb from 710 MCM in the winter of 2023–24 to its current ceiling through a series of incremental operational gains.

The record arrives at a moment of unusual complexity for Iran’s energy sector. The same field that is producing at unprecedented levels is also partially offline: four processing units at Phase 14 were struck by Israeli air attacks in June 2025, leaving a portion of the field’s capacity under repair. That Phase 14 damage was the first direct military strike on Iranian oil and gas infrastructure in the modern era, and it came alongside a simultaneous attack on a Tehran fuel depot and a refinery near the capital.

The production surge is not the result of new phase commissioning but of a sustained operational optimization campaign by Pars Oil and Gas Company (POGC). The central challenge at South Pars is natural reservoir pressure decline: as the field ages, reduced wellhead pressure makes it progressively harder to move gas the 120 kilometers from offshore platforms to onshore processing facilities at Assaluyeh without significant efficiency losses.

To counter this, POGC has deployed domestically-developed pressure-boosting technologies, reduced platform footprint and weight to allow faster domestic fabrication, and constructed new specialized underwater pipelines rated for extreme pressure and corrosion conditions. A new high-productivity well at Phase 13 came online on February 14, adding 60 million cubic feet per day — about 1.7 MCM — after startup was deliberately delayed to coincide with peak winter heating demand. Gas production from Phase 11 reached 20 MCM per day following commissioning of its eighth and tenth development wells.

The underlying infrastructure is formidable: South Pars currently operates 13 gas processing plants, 3,200 kilometers of 32-inch underwater pipelines, and 39 offshore platforms. The field provides over 70% of Iran’s total domestic natural gas supply and serves as the feedstock for approximately 40% of the country’s gasoline production — making any disruption to output immediately felt across the national energy grid, petrochemical sector, and power generation capacity.

Behind the headline production number, a deepening labor crisis is unfolding in Asaluyeh, the industrial city in Bushehr Province that serves as the onshore hub for South Pars. Hundreds of contract workers at multiple refineries — including the 10th refinery of the South Pars Gas Complex — have been on strike over unpaid overtime, inadequate housing, and cuts to benefits. Unofficial South Pars workers reportedly earn around $125 per month, a figure that has been dramatically eroded by the rial’s collapse.

The government’s response has been severe. Approximately 200 workers remain in detention in warehouses belonging to the IRGC’s Khatam al-Anbiya Construction Headquarters, the state entity that serves as the primary contractor across the South Pars industrial zone. Human rights monitors report that communication between detainees and their families has been severed for weeks, and that detainees have had limited access to food and water. The IRGC does not recognize independent unions or labor organizations at the site.

The protests in Asaluyeh preceded the wider December 2025 civil unrest by several weeks, suggesting the energy sector workforce was an early flashpoint for the economic grievances that later spread to Tehran’s Grand Bazaar and universities. This is historically resonant: a 1979 oil worker strike was instrumental in halting exports and weakening the Shah’s government during the revolution.

For energy decision-makers, the South Pars record carries a dual message. Operationally, Iran has demonstrated a capacity to sustain and even grow output from a mature, sanctioned field using primarily domestic technology — a capability that reduces vulnerability to external pressure in the near term and strengthens Tehran’s position as a potential energy supplier to non-Western markets once sanctions architecture shifts.

Structurally, however, the ceiling is visible. Reservoir pressure decline will eventually outpace the gains achievable through optimization alone; the $70 billion pressure-boosting and well-drilling program announced in 2024 requires sustained capital allocation that is difficult under current fiscal conditions. Phase 14’s repair timeline and the ongoing labor unrest introduce operational risk into a field that is simultaneously Iran’s most critical energy asset and one of its most politically sensitive workplaces. Whether the 730 MCM record represents a sustainable plateau or a pre-decline peak will be the defining question for Iran’s domestic energy security through the decade.
