In a major escalation in the Middle East, Israeli strikes have targeted the South Pars mega-field, the worldโs largest known natural gas reserve, which supplies around 70 percent of Iran’s domestic natural gas. In response, Iran has threatened to hit other Gulf energy facilities and issued warnings urging people to evacuate areas near key oil infrastructure in the region.
The attacks have already impacted global energy markets. Brent North Sea crude surged over five percent to $108.60 per barrel, while the main US oil contract, West Texas Intermediate, climbed 1.9 percent to $98.01.
South Pars/North Dome: A critical energy hub
The South Pars/North Dome field is located on the Persian Gulf continental shelf and is shared between Iran and Qatar. The field is divided into two sections: South Pars, under Iranian territory, and North Dome, under Qatari control.ย
Together, they contain an estimated 51 trillion cubic meters of natural gas and around 50 billion barrels of condensate, making them vital for global energy supply.
The gas in the field is primarily sour, requiring advanced processing to remove hydrogen sulfide and other impurities. Iran has developed South Pars in 24 phases, producing natural gas, condensate, and sulfur for domestic use and export. Meanwhile, Qatarโs North Dome has been central to its liquefied natural gas (LNG) industry, enabling the country to become the worldโs largest LNG exporter.
Development of the field involves complex offshore platforms, pipelines, and processing facilities due to technical challenges and the high sulfur content of the gas. Geopolitically, coordination between Iran and Qatar is crucial, and international sanctions and agreements have historically influenced development strategies. The South Pars/North Dome field remains a strategic asset with significant economic and geopolitical importance for both countries and the global energy market.
