Countries With the Most Natural Gas Reserves, Ranked

Russia has the most proven natural gas reserves in the world, about 47.8 trillion cubic meters according to the U.S. Energy Information Administration (EIA), followed by Iran at 34.0 and Qatar at 23.9. But the ranking below the top three depends on whom you ask: the United States, for example, appears with anywhere from 9.1 to 17.7 trillion cubic meters depending on the source. This article lays the numbers side by side and explains what they do and do not mean.

Natural gas is mostly methane. It burns with less carbon dioxide than coal and is widely used for heating, electricity, and industry. Because gas is expensive to move, where it sits underground matters less than whether a pipeline or liquefaction plant connects it to a buyer. That is the main theme here: reserves are a geological fact, but exports are a political and engineering one.

Key takeaways

• Russia, Iran, and Qatar lead every major dataset, with Russia near 47.8 trillion cubic meters (EIA, 2021) and Iran near 34 trillion.
• Sources disagree by up to a factor of two for several countries. U.S. reserves are 17.7 trillion cubic meters in the EIA column, 12.6 in BP's end-2020 data, and 9.1 in OPEC's.
• Qatar's reserves are almost entirely one field, the North Field, which Iran shares as South Pars.
• Russia's gas exports fell from 251 billion cubic meters in 2021 to 176 billion in 2022, after Europe moved away from Russian pipeline gas.
• Natural gas emits about 45 percent less CO2 than coal per unit of energy burned, but methane leaks complicate the full climate picture.

The ranking: top 15 countries by proven natural gas reserves

The table below uses three published datasets as compiled in Wikipedia's reference list of proven reserves: the EIA's International Energy Statistics (2021), the OPEC Annual Statistical Bulletin (2018 to 2024 editions), and the BP Statistical Review of World Energy (end of 2020). The countries are ordered by the EIA column. Units are trillion cubic meters (tcm). One tcm equals 1,000 billion cubic meters (bcm).

Rank (EIA)	Country	EIA 2021 (tcm)	OPEC (tcm)	BP end-2020 (tcm)	Dry gas production, 2024 (bcm)
1	Russia	47.8	46.8	37.4	642
2	Iran	34.0	34.0	32.1	279
3	Qatar	23.9	23.9	24.7	170
4	United States	17.7	9.1	12.6	1,069
5	Turkmenistan	10.0	9.8	13.6	78
6	Saudi Arabia	9.4	9.7	6.0	123
7	China	6.7	2.9	8.4	258
8	United Arab Emirates	6.1	8.2	5.9	59
9	Venezuela	6.0	5.5	6.3	25
10	Nigeria	5.8	6.0	5.5	39
11	Algeria	4.5	4.5	2.3	99
12	Iraq	3.7	3.7	3.5	10
13	Australia	3.2	3.2	2.4	152
15	Kazakhstan	2.4	1.9	2.3	29
16	Canada	2.1	2.1	2.4	199

Why the same country can have two different numbers

The gaps are not errors so much as different judgments. Proven reserves are the volumes that geological and engineering data show can be recovered with reasonable certainty under current economic and operating conditions. That definition leaves room for interpretation. Each compiler decides how to treat shale gas, undeveloped fields, and reports from governments that do not allow independent audits.

Think of reserves as the food in a pantry that you are confident you can afford to eat, not everything in the house. A larger pantry does not by itself feed anyone. You still need a kitchen, a way to carry the groceries, and the money to run both. Gas works the same way: the reserve figure says how much is likely recoverable, not how much will be sold.

The table also shows where the disagreement is largest. China's reserves range from 2.9 (OPEC) to 8.4 tcm (BP). Algeria's go from 2.3 (BP) to 4.5 (EIA and OPEC). Treat any single figure as an estimate and prefer ranges when comparing countries below the top three.

Reserves versus production: how long could each country keep pumping?

Dividing reserves by annual production gives a crude "years of supply at today's rate." It ignores new discoveries and changes in demand, but it shows which countries are drawing down their endowment fastest. The ratios below are my own calculation from the EIA reserves column and 2024 production in the table above, so they mix reporting years.

Country	Approximate years of reserves at 2024 production
Iraq	370
Venezuela	240
Nigeria	150
Qatar	140
Turkmenistan	130
Iran	120
United Arab Emirates	100
Kazakhstan	80
Saudi Arabia	77
Russia	74
Algeria	45
China	26
Australia	21
United States	17
Canada	11

Several patterns appear. Countries with long reserve lives and low output, such as Iraq and Venezuela, are typically limited by infrastructure, investment, or sanctions rather than geology. Iraq produces only about 10 bcm a year from reserves of 3.7 tcm, a small fraction of what the reserves could support. The United States, in contrast, produces more gas than any other country in the table and shows a reserve life under 20 years. That number is a limit of the method, which counts only the reserves booked today and not the volumes added as new wells are drilled.

Iran is the other striking case. It ranks second in reserves and third in production in the table, behind the United States and Russia, yet it does not appear among the top 10 gas exporters in 2022. Much of what it produces is consumed at home.

Who actually sells the gas: top 10 exporters in 2022

Reserves say what lies underground. Export data say who is shipping it to other countries. The two lists overlap only partly.

Rank	Country	Gross gas exports, 2022 (bcm)
1	United States	195
2	Russia	176
3	Qatar	126
4	Norway	121
5	Australia	106
6	Canada	85
7	Algeria	50
8	Turkmenistan	45
9	Netherlands	43
10	Malaysia	39

Source: Wikipedia, List of countries by natural gas exports. The figures are gross exports, so gas that is re-exported after passing through a country is counted again.

Norway, the Netherlands, and Malaysia are major exporters with relatively modest reserves, and Iran, third in production, is absent. Because the figures are gross, some of any country's total can be gas that only passed through it. A country with a small endowment and good export infrastructure can therefore outsell a country with a large one.

A note on units helps when reading industry sources. Most U.S. sources use trillion cubic feet (Tcf), while much of the world uses cubic meters. One trillion cubic meters equals about 35 Tcf, which is why the North Field's 51 trillion cubic meters in place is also quoted as about 1,800 Tcf.

The giant field that two countries share

Most of Qatar's gas and a large part of Iran's come from the same geological structure, called the North Dome on the Qatari side and South Pars on the Iranian side. It lies in the Persian Gulf, with the producing zone about 3,000 meters below the seabed.

The field holds an estimated 51 trillion cubic meters of gas in place, of which about 36 trillion cubic meters is considered recoverable, roughly 19 percent of world recoverable gas reserves. Qatar's recoverable portion is about 25 trillion cubic meters, nearly 99 percent of its proven gas reserves, while Iran's is about 10 trillion cubic meters, about 36 percent of its proven reserves on 2007 estimates (Wikipedia, South Pars/North Dome Gas-Condensate field).

A shared reservoir is like two people drinking from the same milkshake with separate straws. Whatever one side extracts is no longer available to the other, so each country has an incentive to develop its portion quickly. The difference in outcomes comes from what happened after drilling, which is where liquefied natural gas enters the story.

LNG: why a liquid changed the geography of gas

Pipelines tie a seller to a buyer for decades. Liquefied natural gas (LNG) is natural gas cooled to about -162 degrees Celsius, at which it becomes a liquid occupying roughly 1/600th of its gaseous volume. That makes it possible to ship gas in tankers to any port with a regasification terminal (Wikipedia, Liquefied natural gas).

Pipeline gas is like water from a municipal main: reliable, cheap, and available from one supplier. LNG is like bottled water on a truck: costlier per unit, but you can switch brands. That flexibility is why the shape of the market after 2022 looked so different from before.

Wikipedia's older figures show how concentrated LNG exports were. In 2017, Qatar exported 77.5 million tonnes, Australia 55.6 million, and Malaysia 26.9 million, and Qatar supplied an estimated 26.7 percent of the world's LNG; Asia accounted for 72.9 percent of LNG demand. By 2023 the United States had become the world's largest LNG exporter, shipping 4.3 trillion cubic feet according to the EIA (same source). These are older snapshots, so use them for scale, not for the current shares.

Russia: the largest reserves and the largest rerouting

Russia's reserves of about 47.8 tcm are concentrated in Siberia and are the largest of any country. Its position changed sharply after February 2022.

In 2021, Russian pipeline and LNG gas totaled 152 billion cubic meters, about 45 percent of the European Union's gas imports in one source and about 40 percent in another (Wikipedia, REPowerEU). Russia's total gas exports fell from 251 bcm in 2021 to 176 bcm in 2022 (Wikipedia, natural gas exports).

The break came in stages. Gazprom stopped Nord Stream 1 deliveries on August 31, 2022. On September 26, 2022, explosions damaged the Nord Stream 1 and 2 pipelines and left three of the four lines inoperable (Wikipedia, Nord Stream). Transit through Ukraine, which carried about 14.4 bcm in 2023, ended on January 1, 2025, when the contract expired (Wikipedia, Russia-Ukraine gas disputes). The Russian share of EU gas imports fell to under 19 percent in 2024 and about 12 percent in 2025, or 36 bcm, and on June 17, 2025 the European Commission proposed phasing out Russian gas and oil imports by the end of 2027 (REPowerEU source above).

Why Russia cannot simply sell the gas elsewhere

Pipelines are built toward particular customers. The Power of Siberia 1 pipeline to China began deliveries on December 2, 2019 and can supply 38 bcm per year to China. A second route, Power of Siberia 2, remains described as proposed (Wikipedia, Power of Siberia). The 152 bcm that Russia sold to Europe in 2021 was about four times that. Replacing them would take new pipelines and new LNG capacity, both of which take years.

That is the reserve-versus-export gap in action: the gas remained in the ground, but its path to the highest-paying buyers closed. The consequences for the energy trade also show up in the oil context, covered in Countries That Export the Most Oil and Countries With the Most Oil Reserves.

Iran: second in reserves, mostly absent from exports

Iran's 34 tcm is the second-largest endowment on every list, yet it is not among the top 10 exporters. Iran produced about 279 bcm in 2024 in the table above, which suggests large domestic use, and reserves of that size cannot be fully developed without capital, equipment, and customers.

Iran's recoverable share of the shared field is about 10 trillion cubic meters, compared with Qatar's 25 trillion, so the neighbors hold different volumes of the same structure. The contrast between the two sides likely reflects investment, technology access, and market reach, not just geology. Beyond that, forecasts about what Iranian exports could become depend on politics and sanctions, which no dataset can predict. This article does not forecast prices or recommend any investment.

Qatar: one field, turned into an LNG powerhouse

Qatar's 23.9 tcm is close to the entire North Field. Qatar's LNG output was about 77 million tonnes in 2025 and is expected to reach 126 million tonnes by 2027 under its expansion plans, according to the Wikipedia article on the field, which also notes that project schedules can shift. The country's position rests on exporting a high share of what it produces. Its production was 170 bcm in the table above, about 16 percent of U.S. output, yet Qatar ranked third in 2022 gross gas exports at 126 bcm, behind the United States (195 bcm) and Russia (176 bcm).

That ratio, exporting most of what you produce, is why Qatar matters to gas importers far more than its 170 bcm would suggest. For how energy-rich states hold and invest their export income, see Countries With the Largest Sovereign Wealth Funds.

The United States: modest reserves on paper, largest exporter in practice

The United States has the widest spread of estimates among major holders, from 9.1 to 17.7 tcm. Its importance rests on production instead. At 1,069 bcm in 2024, it is the largest producer in the table, more than Russia (642) and Iran (279) combined.

U.S. gas exports hit a record 6.90 trillion cubic feet in 2022 according to the EIA, with about 44 percent moving by pipeline to Mexico and Canada and the rest as LNG. LNG exceeded pipeline exports for the second consecutive year in 2022, and exports began from the lower 48 states only in 2016 (EIA, imports and exports). In 2022 gross exports were 195 bcm, the world's highest.

The shift shows how a country can pass from importer to leading exporter within a decade without any change in the underlying geology, because hydraulic fracturing and horizontal drilling unlocked shale formations that were not previously economical. In 2018, shale gas contributed 23.6 trillion cubic feet, 63 percent of U.S. gas production (Wikipedia, Natural gas in the United States). For readers curious about how that technology interacts with other energy sources, the closest comparison on this site is the ranking of Countries with the Most Natural Resources.

Turkmenistan: large reserves, one dominant customer

Turkmenistan's reserves are between 9.8 and 13.6 tcm depending on the source, and its output is about 78 bcm. It has no ocean coastline, so it cannot ship LNG directly, and a large share of its exports go east through the Central Asia-China pipeline. The pipeline's lines A through C have a combined capacity of 55 bcm per year, reached by 2015, and a 2023 statement from Turkmenistan's foreign ministry put its quota on the system at 40 bcm a year. More than half of Turkmenistan's gas exports go to China, and a fourth line (Line D) would raise total capacity to 85 bcm per year (Wikipedia, Central Asia-China gas pipeline).

Turkmenistan was the eighth-largest gas exporter in 2022 at 45 bcm. Dependence on one buyer limits its bargaining power: a country with a large reserve and one customer holds a weaker hand than one with several. The ranking in Countries That Export the Most Oil makes a similar point for crude.

What natural gas does to the climate, and what it does not

The usual argument for gas as a "bridge fuel" rests on combustion. EIA coefficients based on 2022 data put natural gas at 52.91 kilograms of CO2 per million Btu, compared with 95.99 for coal of all types. That is about 45 percent less (EIA, Carbon Dioxide Emissions Coefficients).

The caveat is methane. Methane has a global-warming potential of about 84 times that of CO2 over 20 years and 28 times over 100 years, and leaks from wells, pipelines, and processing can offset some of the combustion advantage. Life-cycle estimates are about 50 percent higher than direct emissions at the point of use, with substantial uncertainties (Wikipedia, Natural gas). For more on the gas itself, see Why Methane Matters for Climate Change.

Gas-fired plants generate over 20 percent of the world's electricity according to the same source, which is why gas sits at the center of discussions about backing up wind and solar power. Questions about storage and the grid are covered in Why Grid Storage Is Hard, and the renewable share by country in Countries That Run on the Most Renewable Electricity.

Why a reserve ranking can change without a single new well

Reserve tables move for reasons that have little to do with geology. A new discovery adds volume, but so do a rise in price that makes marginal fields economic, a technology change, or simply a government publishing a different audit. Mozambique, listed at about 3 tcm in the EIA table, shows how fast a country can enter the top 15. Conversely, estimates can fall when assumptions are revised, which is partly why China's range runs from 2.9 to 8.4 tcm.

The practical lesson is to cite reserves with their source and year, and to prefer production and export data when the question is about actual supply. Gas that has never been connected to a market is, for most economic purposes, not yet an asset.

Frequently asked questions

Q: Which country has the most natural gas reserves? A: Russia, with about 47.8 trillion cubic meters according to the U.S. EIA (2021), 46.8 in OPEC data and 37.4 in BP's end-2020 data. Iran is second at about 34 trillion and Qatar third at about 24 trillion in all three sources.

Q: Why do the numbers differ between sources? A: Each compiler applies its own definition of "proven," treats shale and undeveloped fields differently, and relies on government reports that may not be independently audited. U.S. reserves, for example, are 17.7 tcm in the EIA column, 12.6 in BP's, and 9.1 in OPEC's.

Q: What is LNG, and why does it matter for rankings? A: LNG is natural gas cooled to about -162 degrees Celsius so that it becomes a liquid roughly 1/600th the volume, allowing transport by ship. It lets countries without pipeline links to buyers, such as Qatar and Australia, sell gas globally, and it turned the United States into the largest exporter by 2023.

Q: Why can't Russia redirect its European gas to Asia? A: Russia's pipelines were built toward Europe. The Power of Siberia 1 line to China supplies 38 billion cubic meters a year, a fraction of the 152 bcm Russia sent to the EU in 2021, and a second route is still only proposed. Replacing the lost volume requires new pipelines or LNG plants, which take years.

Q: Is the United States a major gas reserve holder? A: Estimates range from 9.1 to 17.7 trillion cubic meters, and it ranks fourth in the EIA column. But the United States is the world's largest producer at about 1,069 bcm in 2024 and the largest gross exporter in 2022 at 195 bcm.

Q: Is natural gas cleaner than coal? A: At the point of combustion, yes: EIA coefficients show about 45 percent less CO2 per unit of energy. Methane leaks upstream can narrow that advantage, and estimates carry substantial uncertainty.

Q: How many years of gas are left? A: A crude calculation dividing reserves by current production gives about 17 years for the United States, 74 for Russia, 140 for Qatar, and more than 100 for Iran and Turkmenistan. The figures change when new fields are found or demand shifts, so they are indicators, not forecasts.

The takeaway

The cleanest reading of a gas reserve ranking is that it describes potential, not supply. Russia, Iran, and Qatar sit on the three largest proven reserves, yet in 2022 the top three exporters were the United States, Russia, and Qatar, in that order, and Iran was outside the top 10. What separates those lists is pipelines, liquefaction plants, sanctions, and customers.

For readers tracking energy markets, the safest habits are to note the source and year of every reserve figure, to compare production and export data alongside reserves, and to remember that a country can move between these lists within a decade. The 2022 reordering of Europe's gas supply happened in months, even though not one cubic meter of reserve had changed.
