The company, which oversees development of Iran’s shared and standalone offshore gas fields, carries a dual mandate: supplying about 70% of domestic gas demand, feedstock for roughly 40% of gasoline production and 50% of petrochemical complexes during normal and peak periods, while preparing capacity to meet rising energy demand in coming years. Measures taken over the past 15 months—focused on high-impact, lower-cost and quick-return projects—have delivered notable results.

Fourteen new wells brought online

According to Pars Oil and Gas Co., 14 new wells were brought into production at South Pars during the current administration, including four infill wells and 10 development wells in Phases 11, 13 and 14. The additions increased gas capacity by about 25 million cubic meters per day, helping offset natural decline, stabilize winter supply and improve the country’s energy balance.

Beyond stabilizing output, the wells enabled new production records and reduced the risk of supply curbs for households, industry and power generation.

Record-setting winters

Production gains in the winters of 1403 and 1404 (Iranian calendar) set unprecedented daily records for rich gas output at South Pars. In winter 1403, daily output reached 710, 712, 714 and ultimately 716 million cubic meters.

The upward trend continued in 1404, with successive records of 718, 722, 723 and 725 million cubic meters. In Bahman 1404, output peaked at 727 million cubic meters per day—the highest level in two decades of production—underscoring the field’s critical role in gas network stability, power plant fuel supply and industrial operations during peak demand.

Expanded drilling capacity

Since the start of the current administration, six drilling rigs have been added to the fleet under contract with Pars Oil and Gas Co. Two rigs were deployed for infill drilling, one at the shared Balal field and three for Phase 13 development. The added capacity has enabled parallel drilling campaigns, reduced idle time between operations and strengthened execution, despite ongoing international sanctions affecting the oil industry.

$500m in value creation

In 1404, major overhauls were completed on 35 offshore platforms at South Pars over 179 days, involving about 160,000 labor hours and more than 16,000 work orders. In 1403, 33 platforms were overhauled over 207 days.

Shorter overhaul cycles lifted rich gas output by about 1.5 billion cubic meters and increased daily deliveries to the national grid by the equivalent of 21 million cubic meters. The added production carries an estimated energy value equal to 9 million barrels of crude oil, worth about $500 million at $60 a barrel.

The experience shows that process improvements and optimized asset management can yield significant economic gains without heavy capital spending.

Logistics capacity was also strengthened with the addition of a 100-berth accommodation and support barge, enhancing operations across 39 offshore platforms spread over 3,700 square kilometers of the Persian Gulf and supporting safer, more reliable production.

Infill drilling as a short-term solution

Four infill wells brought online under the current administration added about 7 million cubic meters per day to South Pars capacity. The program is viewed as one of the most effective short-term measures to manage reservoir pressure decline, complementing larger compression projects and buying time for long-term planning.

Phase 11 production surge

Phase 11 of South Pars now has 10 producing wells, with daily output rising from 12 million cubic meters in late Mordad 1403 to more than 24 million cubic meters. The 10th well, commissioned this winter, adds 2.4 million cubic meters per day.

A second jacket for Phase 11 was loaded earlier this year and installed in Dey, paving the way for a new drilling rig. Fifteen wells are planned at the second location, expected to bring the phase to its nameplate capacity. The Phase 11 development targets 2 billion cubic feet per day of rich gas.

Key actions in Phases 13, 14 and 16

Extensive acidizing operations on three wells at the SPD13B platform improved flow conditions and boosted output. At Phase 14, technical, safety and environmental measures were implemented, including commissioning an environmental unit at the onshore refinery to reduce emissions and environmental impacts in the Kangan area. Offshore, completion of two new wells increased production by about 4 million cubic meters per day.

Rapid recovery after damage

Phase 14 facilities were damaged during an attack on Iran’s energy infrastructure, temporarily halting part of capacity. Emergency measures focused on safety, containment and risk control. Repairs began immediately, and within 10 days two affected units were returned to service, highlighting operational resilience and domestic engineering capability.

At Phase 16, well safety upgrades and commissioning of a new onshore pipeline section supported stable production and gas transfer to the refinery.

Advancing future fields

Progress was also reported at the Kish, Balal, Farzad B and North Pars fields. At Kish, three new wells were completed, bringing ready-to-produce wells to 10, alongside plans for the Bandar Aftab refinery. At Balal, jacket installation was completed and drilling began. At Farzad B, basic engineering advanced, the 2,650-ton WHP1 jacket reached more than 95% completion and is expected to be installed by year’s end. At North Pars, seabed studies were completed and a contract signed for the first-phase jacket.

Preparing for pressure boosting

For South Pars pressure boosting, two cooperation agreements covering studies and oversight of basic engineering for Hubs 3 and 6 were signed this winter. Basic and advanced engineering has been completed, milestones set for short-, medium- and long-term horizons, and specialized studies—including environmental, geotechnical and seismic assessments—finalized. The work lays the groundwork for one of Iran’s most strategic gas projects, seen as essential to sustaining output in coming decades.

Pars Oil and Gas Company’s 15-month record under the current administration reflects simultaneous management of production, efficiency gains, new capacity development and preparation of strategic projects—strengthening its role as the backbone of Iran’s gas supply and energy security.
