I found this eye-opening.
From Zerohedge.com:
Oil is a natural resource formed by the decay of organic matter over millions of years, and like many other natural resources, it can only be extracted from reserves where it already exists. The only difference between oil and every other natural resource is that oil is well and truly the lifeblood of the global economy.
The world derives over a third of its total energy production from oil, more than any other source by far; and, as Visual Capitalist’s Anshool Deshmukh details below, as a result, the countries that control the world’s oil reserves often have disproportionate geopolitical and economic power.
According to the BP Statistical Review of World Energy 2020, 14 countries make up 93.5% of the proven oil reserves globally. The countries on this list span five continents and control anywhere from 25.2 billion barrels of oil to 304 billion barrels of oil.
