The Middle East remains the undisputed epicenter of concentrated reserves, with nations like Venezuela, Saudi Arabia, Canada, and Iran holding the largest shares.
Undiscovered Oil Reserves Worldwide in 2024: Assessing the Potential
Economic Viability and the Cost of Extraction Not all oil is created equal, and the cost of extraction varies wildly across different deposits. Venezuela’s Orinoco Belt contains vast quantities of extra-heavy crude, though extracting it profitably presents significant technical hurdles.
These regional concentrations mean that political stability and regulatory frameworks are just as important as geology in determining how much oil the world can actually access. The Shale Revolution and Technological Disruption One of the most significant factors altering the conversation about remaining oil is the shale revolution, primarily driven by the United States.
