The United States, particularly the Permian Basin in Texas and the Bakken Formation in North Dakota, has experienced an energy boom. The Middle East remains the most concentrated area, holding over half of the world's proven oil reserves.
Global Oil Reserves Distribution and Key Reserve Locations
These reservoirs are the result of ancient organic matter being buried, heated, and transformed under immense pressure, creating the black gold we extract today. Rank Country/Region Estimated Reserves (Barrels) 1 Venezuela (Orinoco Belt) ~300 Billion 2 Saudi Arabia ~267 Billion 3 Canada (Oil Sands) ~170 Billion 4 Iran ~157 Billion 5 Iraq ~145 Billion Beyond the Surface: Offshore and Unconventional Frontiers While the map of conventional oil fields is well-trodden, the frontier of exploration is rapidly expanding into challenging environments.
The stability and volume of these reserves continue to dictate global pricing and supply strategies. Oil is not a substance floating uniformly on the Earth's surface; instead, it exists in specific geological formations deep underground, concentrated in distinct regions that have been shaped by millions of years of tectonic and biological processes.

Furthermore, unconventional sources like oil sands in Canada and shale plays in the US represent a significant portion of the world's total oil supply. These resources require more complex extraction methods, but they are crucial for meeting future global demand.
