Countries with the largest proven crude oil reserves

The global energy landscape is fundamentally shaped by the distribution of crude oil, a resource that remains the backbone of industrial economies.

As of 2024, the world’s proven oil reserves are characterised by a heavy concentration in a handful of nations, with Venezuela and Saudi Arabia standing at the pinnacle of global supply.

Venezuela holds the world’s largest proven reserves, boasting 303 billion barrels. This accounts for roughly 19.4% of the global total, though much of this is heavy crude which requires significant investment to refine.

Close behind is Saudi Arabia, with 267 billion barrels (17.1%). Unlike Venezuela, Saudi Arabia’s reserves are known for being relatively easy and inexpensive to extract, cementing its role as the world’s most influential "swing producer" in the energy markets.

The Middle East dominates the middle tier of this ranking. Iran (209 billion barrels) and Iraq (145 billion barrels) hold substantial shares of nearly 13.3% and 9.3% respectively.

These are followed by the United Arab Emirates and Kuwait, both surpassing the 100-billion-barrel mark. Together, these nations form the traditional core of global oil production capacity.
