Platform Overview
Built for energy investors, researchers, analysts, and strategic buyers.
Oil reserves are estimated recoverable quantities of crude oil under current technical, economic, and operating conditions. Rankings can vary by source because methodologies differ, especially around unconventional oil, sanctions, reserve audits, and reporting standards.

#3
Iran
208.6B barrels
Large conventional reserves; output/export levels affected by sanctions and policy constraints.
#4
Canada
163.1B barrels
Major reserves are concentrated in Alberta oil sands.
#5
Iraq
145.0B barrels
Large low-cost reserves centered around southern supergiant fields.
#6

Why Oil Reserves Matter
Reserve size influences national energy security, export capacity, sovereign wealth, geopolitical leverage, infrastructure investment, and long-term petroleum strategy. However, large reserves do not always equal high production; political risk, sanctions, field quality, investment levels, and technology all matter.
Regional Concentration
The Middle East remains the central reserve region, while North America, South America, Russia, and Africa hold major strategic basins. Unconventional resources such as oil sands and shale have changed how analysts evaluate reserve quality and development economics.
