Sanctions vs. Sovereignty – Iran’s lag and Qatar’s LNG dominance
North Dome–South Pars gas field becomes major flashpoint between Qatar and Iran
The North Dome–South Pars gas field, the largest natural gas reservoir in the world, has emerged as a critical geopolitical flashpoint in the Gulf region, physically connecting two long-standing rivals: Qatar and Iran.
The offshore field holds an estimated 1,800 trillion cubic feet of recoverable natural gas along with billions of barrels of condensate, making it a cornerstone of regional energy security [1]. While Qatar manages the northern portion, known as the North Dome, Iran operates the southern section, South Pars.
Experts describe the field as a textbook “tragedy of the commons” scenario. Because gas is fluid, aggressive extraction on one side affects the pressure and output of the other. Qatar began developing its North Dome section aggressively in the 1990s, leveraging Western companies such as TotalEnergies and Shell to build state-of-the-art production and liquefaction facilities [2]. In contrast, Iran’s development lagged for decades due to international sanctions and the aftermath of war, relying primarily on domestic contractors.
This imbalance has caused Tehran to fear that Qatar’s rapid extraction could cause gas to migrate across the border, effectively reducing Iran’s recoverable reserves. A detailed study examining the dispute notes that while the exact scale of migration is debated, the perception of loss has repeatedly fueled tension between the two nations [3].
The disparity in development has had profound economic consequences. While Qatar has become a global LNG superpower, Iran’s constrained production has limited export potential, forcing it to depend on domestic consumption for electricity generation and residential heating [4]. This technological and economic gap has created deep resentment in Tehran, where policymakers view the field as a shared national asset being compromised.
Beyond economics, the North Dome–South Pars field is a strategic vulnerability. Concentrated offshore platforms, pipelines, and processing facilities make it a high-value target. Any disruption to Qatar’s section would threaten its LNG exports and government revenues, while damage to Iran’s portion could trigger electricity shortages and social instability domestically. Analysts warn that this dual dependence makes the field a focal point in any escalation of regional tensions [2].
Despite these challenges, both countries have so far avoided direct confrontation. While Qatar continues to expand its LNG production and export network, Iran has accelerated South Pars development where possible, emphasizing domestic investment and technology. However, the lack of a formal joint management framework means the reservoir remains politically and economically sensitive.
The North Dome–South Pars gas field illustrates the intricate interplay of geology, technology, and geopolitics. Its enormous energy potential makes it both an economic boon and a strategic liability. As global energy demand grows and regional dynamics shift, the field will likely continue to serve as one of the Middle East’s most sensitive and high-stakes energy flashpoints.
