Here's what's interesting: if you look at global energy resources, it becomes clear that oil reserves are distributed extremely unevenly across countries, and this creates a completely different hierarchy of power on the world stage.

Venezuela has the largest proven oil reserves on the planet — about 303 billion barrels, mainly in the Orinoco region. Almost one-fifth of all global oil reserves are concentrated in one country. But here’s the paradox: despite these resources, the country produces less than a million barrels per day. Political instability, sanctions, and infrastructure degradation have turned this wealth into a curse. Most of Venezuelan oil is extra-heavy, difficult to process, and requires huge investments.

Saudi Arabia ranks second with 267 billion barrels, but what’s important is that their oil is easily accessible and cheap to extract. This gives Saudi Arabia real power in the market. They actively use this position in OPEC+ negotiations, acting as a “regulating producer.” When Riyadh changes production volumes, it influences global prices.

Iran with 209 billion barrels ranks third, but international sanctions have seriously limited its export capabilities. Interestingly, in 2025, Iranian exports reached a seven-year high despite restrictions — showing how the country finds loopholes and alternative sales channels.

Canada with 163 billion barrels mainly has Alberta’s oil sands. Extraction there is costly and energy-intensive, but Canada remains a major exporter, especially to the US. Iraq with 145 billion barrels is a serious player in the Middle East, although internal conflicts and political instability slow down its potential.

In fact, the Middle East controls about 48% of all global oil reserves by country. Besides the already mentioned, the top 10 includes the UAE, Kuwait, each with reserves over 100 billion barrels. Russia holds more than 80 billion barrels and remains a key exporter, especially to Europe and Asia, although sanctions affect its production.

The US ranks tenth in reserves, but that hasn’t stopped it from becoming one of the largest producers thanks to shale oil extraction technology. This truly shows that it’s not just about underground wealth, but also about technology, political stability, and market access.

When analyzing the distribution of oil reserves by country, it becomes clear: energy geopolitics is the key to understanding international relations. Whoever controls the oil influences prices, economies, and even political decisions of neighboring states.
