Grok - Which country has the largest proven oil reserves on the planet ?
Venezuela has the largest proven oil reserves in the world, with approximately 303 billion barrels as of the latest available data (end of 2024 from OPEC's Annual Statistical Bulletin 2025 and consistent across multiple sources).
This is significantly more than the second-place country, Saudi Arabia, which holds about 267 billion barrels.
Other top countries include Iran (209 billion barrels) and Canada (163 billion barrels, largely from oil sands).
These figures represent "proven" reserves—oil that is economically recoverable with current technology and market conditions. Venezuela's reserves are primarily heavy crude from the Orinoco Belt, which is more challenging and costly to extract compared to Saudi Arabia's lighter, more accessible oil. Sources like OPEC, World Population Review, Visual Capitalist, and industry reports (e.g., Oil & Gas Journal) consistently rank Venezuela first, with no major changes reported into early 2026.
