Country profile · Qatar · World's largest gas field, shared with Iran

Qatar Energy

Qatar left OPEC in 2019 to focus entirely on natural gas, and is now spending tens of billions of dollars expanding LNG capacity by 85% to defend its position among the world's top exporters — all drawn from a single reservoir it shares, uneasily, with Iran.

One field, shared uneasily

The North Field — and the country on the other side of it

The world's largest gas reservoir:
Qatar's gas wealth is almost entirely concentrated in a single offshore reservoir — the North Field — which happens to be the largest non-associated natural gas field on Earth. It doesn't respect the maritime border: Iran calls its share South Pars, and both countries have developed the field independently on their own sides. Fresh appraisal drilling in 2024 found an additional 240 trillion cubic feet of gas in the field's western reaches, pushing Qatar's total reserves from roughly 1,760 to over 2,000 trillion cubic feet — enough to sustain decades more production even before considering further discoveries.
A field development paused by a regional conflict:
Qatar halted further North Field development for 12 years under a self-imposed moratorium, worried about depleting pressure too quickly, before lifting it in stages between 2017 and 2021. Construction on the North Field East expansion — the first phase of the current buildout — was paused in 2026 after the broader Iran-Israel-US conflict that began that February disrupted the region, pushing the project's first-cargo timeline into later 2026. It's a direct reminder that sharing the world's largest gas field with a country at the center of a major regional conflict carries real operational risk, even for a project as commercially critical to Qatar as this one.
Betting everything on LNG

Why Qatar left OPEC, and what a 142 mtpa target means

The 2019 pivot:
Qatar left OPEC in January 2019 — one of the group's longest-standing members at the time — explicitly citing a decision to shift national resources away from oil toward natural gas. That strategic bet has defined Qatari energy policy since: state company QatarEnergy is now executing three sequential LNG expansion phases (North Field East, North Field South, North Field West) that will lift total liquefaction capacity from 77 million tonnes a year in 2024 to 142 million tonnes by the end of 2030, an 85% increase, backed by tens of billions of dollars in investment.
Defending a market position:
Qatar has historically ranked among the world's top two LNG exporters, trading the top spot with the United States and Australia depending on the year as US export capacity has grown rapidly. The 142 mtpa target is explicitly designed to keep Qatar competitive at that scale, aiming for close to a quarter of the projected global LNG market by 2030. Most Qatari LNG goes to Asia, with a smaller share to Europe; Qatar also supplies pipeline gas regionally to the UAE and Oman via the Dolphin Pipeline. Despite Vision 2030 diversification efforts, hydrocarbons — LNG, crude oil, and petroleum products combined — still generate more than half of total government revenue.
Questions

Questions about Qatari energy

Why did Qatar leave OPEC, and was it really just about natural gas?
Qatar's own stated reason was economic: it wanted to shift national investment and diplomatic energy toward natural gas rather than being bound by OPEC's oil-production quota decisions, which apply to crude oil, not LNG. As a relatively small oil producer but the dominant force in one of the world's largest gas fields, Qatar's economic interests had genuinely diverged from OPEC's core oil-exporting members for years before the 2019 exit — LNG export volumes, not oil quotas, were what actually moved Qatar's economy. That said, the timing came during a period of significant regional tension: Qatar had been under a diplomatic and trade blockade by Saudi Arabia, the UAE, Bahrain, and Egypt since 2017, and leaving an organization historically dominated by Saudi Arabia was widely read as a symbolic assertion of independent foreign policy as much as a pure economic decision. Both things can be true at once — the gas-focused rationale reflected real, longstanding economic logic, while the timing also fit a broader moment of Qatar demonstrating it didn't need to move in lockstep with its Gulf neighbors.
