World Oil Statistics
The world holds about 1,740 billion barrels of proven oil reserves, produced roughly 106.3 million barrels a day and consumed about 104.4 million barrels a day in 2025. At current output that reserve base is about 45 years of supply — not a forecast, just reserves divided by production. Every figure below is sourced and dated; nothing here is a live meter.

| Proven oil reserves (world) | 1,740 Bn bbl | 2026-08-16 · OPEC ASB / EIA / national sources |
| Years of supply at current production (R/P) | 45 years | Computed: reserves ÷ (production × 365) |
| World oil production | 106.29 Mb/d | 2025 · EIA Short-Term Energy Outlook |

| Supply surplus | 1.89 Mb/d | Computed: production − consumption |
Reserves are hand-curated from OPEC, EIA and national publications (same data as oil reserves by country); production and consumption are the EIA's own official world estimates, also used on world oil demand. Nothing on this page is an animated or real-time counter — every number is a dated, sourced figure.

World totals are approximate, rounded figures illustrating the trend and major reclassification events, hand-curated from OPEC Annual Statistical Bulletin / BP Statistical Review of World Energy historical editions (methodologies and country self-reporting differ between sources, so treat these as order-of-magnitude, not audited figures). Refresh opportunistically when a new OPEC ASB or equivalent historical compilation is checked. Full history and the reclassification events behind the jumps are on oil reserves history.

A dash means no reliable sourced figure for that country, never zero. Reserves as of each row's own 2023-era publication; production/consumption as of each country's latest reporting year (laggards report later — see world production & consumption for exact per-row dates). R/P uses each row's own reserves and production, so it isn't comparable to the world R/P above when only one of the two is available.
World Oil Statistics FAQ
How much oil does the world have left?
About 1,740 billion barrels of proven reserves worldwide, hand-curated from OPEC, EIA and national sources. At the 106.3 Mb/d the world produced in 2025, that is roughly 45 years of supply at current output — a reserves-to-production (R/P) ratio, not a countdown to running out (see below).
How much oil does the world produce and consume per day?
The EIA estimates world petroleum production at 106.3 million barrels a day and world liquid-fuels consumption at 104.4 million barrels a day in 2025, a modest supply surplus that builds inventories.
Will the world run out of oil?
Not on any predictable timeline. The global R/P ratio has stayed remarkably close to 50 years for decades despite continuous production, because rising prices and better technology keep converting previously uneconomic resources into proved reserves about as fast as the world produces them. See proved vs. probable reserves for why the "years left" figure keeps not happening, and peak oil for the demand-side version of this question.
Which country leads in reserves, production and consumption?
Three different countries. Venezuela holds the largest proven reserves (303 billion barrels) but produces a fraction of that rank suggests. United States is the largest producer (13.7 Mb/d). United States is the largest consumer (20.7 Mb/d). Reserves, production and consumption rank differently because geology, investment and demand are three separate things.
Why do some countries have no reserves figure?
Proven reserves are hand-curated from official national and OPEC publications for the largest holders; smaller producers and most consumer-only countries aren't included because there's no clean, comparably sourced figure for them. A blank cell means no reliable figure, never zero.
