Oil Wealth Across Southwest Asia: Country-by-Country Distribution

Southwest Asia (the Middle East) holds ~50% of world proven oil reserves, but distribution is highly uneven:

Super Giants

• Saudi Arabia: ~267 billion barrels (17% global). Ghawar (world's largest onshore field), Safaniya (largest offshore). Eastern Province.
• Iran: ~208 billion barrels. Khuzestan Province (Ahvaz, Marun, Gachsaran). Sanctions limit export.
• Iraq: ~145 billion barrels. Basra (Rumaila, West Qurna), Kirkuk (north). Post-2003 recovery ongoing.
• Kuwait: ~102 billion barrels. Burgan field (2nd largest globally). Small land, huge wealth.
• UAE: ~98 billion barrels. Abu Dhabi (94% of UAE reserves: Zakum, Umm Shaif). Dubai minor.

Major Producers

• Qatar: ~25 billion barrels oil; but world's largest LNG exporter (North Field — shared with Iran's South Pars).
• Oman: ~5.3 billion barrels. Enhanced oil recovery (EOR) critical; PDO (Petroleum Development Oman) leads.

Modest / Declining

• Yemen: ~3 billion barrels. Marib, Shabwa. Conflict halted development.
• Bahrain: ~0.1 billion barrels (Bahrain Field). First Gulf producer (1932); now mature, declining.
• Syria: ~2.5 billion barrels. Northeast (Deir ez-Zor). War disrupted.
• Jordan, Lebanon, Israel, Palestine: Minimal proven oil; recent offshore gas discoveries (Leviathan, Zohr, Karish) transform energy outlook.

Cyprus

Exploratory drilling in Exclusive Economic Zone (EEZ) — Aphrodite gas field; oil potential unproven. Geopolitics (Turkey, EU) complicate development.

Drivers of Variation

Geology (basin history), politics (sanctions, war), technology (EOR, fracking), OPEC+ quotas, and energy transition policies.
