Tunisia Resource Reserves (2026)

1980

2025

What to know

Tunisia had a diversified reserves profile spanning oil and gas. Its holdings came to 0.425 billion barrels of oil and 2.300 trillion cubic feet of gas. EIA stopped publishing oil and gas proved reserves in 2023; the figures above use the latest archived release, while coal continues to update through 2023. Beyond fossil fuels, Tunisia is a top-ten producer of Phosphate Rock among USGS-tracked critical minerals.

Key terms

Proved reserves: — Quantities of crude oil or natural gas that geological and engineering data demonstrate with reasonable certainty are recoverable under existing economic and operating conditions.
Recoverable reserves: — Coal that can be technically and economically extracted with current mining methods at current prices. Excludes inaccessible deposits.
Billion barrels (B bbl): — Unit for oil reserves. One barrel equals 42 US gallons or about 159 litres.
Trillion cubic feet (TCF): — Unit for natural gas reserves. One TCF is roughly 28.3 billion cubic metres.
Million short tons (M ST): — Unit for coal reserves. One short ton equals 2,000 lb or 907 kg.

Crude oil proved reserves

In 2021, Tunisia had 0.425 billion barrels of proved crude oil reserves. Over the prior decade, those reserves held roughly steady.

Natural gas proved reserves

In 2021, Tunisia held 2.300 trillion cubic feet of proved natural gas reserves. Reserves held roughly steady over the prior decade.

The bottom line

Tunisia held meaningful stocks across oil and gas, which gave it flexibility across global energy markets.

Critical minerals (USGS)

Tunisia produces Phosphate Rock among USGS-tracked critical minerals.

USGS marks 2025 production figures and all reserve estimates as estimated; some earlier production years are USGS estimates as well. Each commodity below charts its own mine-production history, with the 2025 reserve shown beneath its chart.
