Oil storage capacity in the Middle East is concentrated in three dominant markets — Saudi Arabia, the UAE, and Iran — which together account for the majority of the region’s estimated 500+ million barrels of operational tank farm, strategic reserve, and terminal storage. The ranking below covers all ten significant storage nations, drawing on independent estimates from S&P Global Energy, Vortexa, and public operator disclosures.
Exact country-level figures are not publicly audited. State-owned operators across the region do not disclose total storage inventories. The estimates below represent the most reliable available assessments from market intelligence sources, combining strategic petroleum reserves, commercial terminal capacity, refinery tankage, and fixed offshore infrastructure.
How We Ranked Oil Storage Capacity Middle East Countries
Countries are ranked by estimated total operational storage capacity. This includes strategic petroleum reserves, commercial tank terminal capacity, refinery tankage, and fixed offshore loading infrastructure. Floating storage fleets — most relevant to Iran — are excluded to maintain comparability across the ranking. Oil storage capacity in the Middle East varies sharply between dedicated export hubs and transit-focused facilities, so context is provided for each entry.
1. Saudi Arabia — 150–180 Million Barrels
Saudi Arabia holds the largest oil storage capacity in the Middle East. The primary complexes are Ras Tanura on the Gulf coast — the world’s largest crude oil port, with over 50 million barrels of tank farm capacity — and King Fahd Industrial Port at Yanbu on the Red Sea, handling crude, refined products, and petrochemicals for European and North American markets.
Strategic tankage also runs along the East-West Pipeline corridor, allowing Hormuz bypass at scale. The Saudi Arabia tank storage network covers Abqaiq, Ju’aymah, Rabigh, and the Ras Tanura/Yanbu export complexes in full, supporting combined export capacity of over 7 million barrels per day.
2. United Arab Emirates — 110–130 Million Barrels
The UAE’s oil storage capacity in the Middle East ranking reflects strategic infrastructure investment as much as production volume. The Fujairah complex on the Gulf of Oman hosts one of the world’s largest commercial crude storage hubs — over 18 million cubic metres of tank capacity across the port zone — plus the 42-million-barrel underground Fujairah Strategic Storage Facility, which operates independently of the Strait of Hormuz.
Abu Dhabi’s infrastructure at Jebel Dhanna, Das Island, and the ADCOP pipeline termination at Fujairah adds further capacity. The UAE tank storage overview covers operators and capacity data across both emirates in detail. For a port-level breakdown, the Fujairah tank storage guide covers the 18-million-cbm hub and current expansion status.
3. Iran — 70–80 Million Barrels (Onshore)
Iran’s onshore oil storage infrastructure is anchored by Kharg Island, which handles roughly 90% of the country’s crude exports and holds approximately 28 million barrels of tank farm capacity. The Jask Terminal on the Gulf of Oman and Qeshm Island provide secondary onshore hubs, with Jask positioned as a Hormuz-independent export alternative.
Iran routinely supplements onshore capacity with 30–60 million barrels of floating storage via its domestic tanker fleet. That figure fluctuates with sanctions pressure and is excluded from this ranking’s onshore comparison.
4. Iraq — 50–60 Million Barrels
Iraq’s storage infrastructure centres on the Al-Faw Peninsula, where the Al Başrah Oil Terminal (ABOT) and Khawr al-Amīyah Terminal (KAAOT) handle the country’s deepwater crude exports. ABOT processes over 3.3 million barrels per day and sits alongside extensive onshore tank farms. Expansion at Fao and plans for a new grand port have added rated capacity, though midstream underinvestment has historically constrained actual throughput.
5. Kuwait — 40–50 Million Barrels
Kuwait’s storage is concentrated at Mina Al-Ahmadi and Mina Abdulla, the two principal export complexes operated by the Kuwait Petroleum Corporation. Combined, the terminals handle approximately 41 million tonnes of crude and products annually. Al-Zour has replaced Mina Al-Ahmadi’s legacy LNG function; that capacity has since been repurposed for crude and product storage, adding to effective throughput.
6. Oman — 25–35 Million Barrels
Oman’s most significant storage addition is the Ras Markaz Crude Oil Storage Terminal on the Arabian Sea coast, designed for up to 200 million barrels at full build-out — the largest greenfield storage project in the region. Current operational capacity is a fraction of that, but Ras Markaz has already attracted leasing interest from Gulf producers seeking Hormuz-independent export routes. Existing infrastructure at Mina Al-Fahal and Sohar brings current operational totals to 25–35 million barrels.
7. Qatar — 15–20 Million Barrels
Qatar’s storage infrastructure reflects its identity as an LNG exporter. Crude tankage is anchored at Halul Island, a dedicated offshore loading platform in the Gulf. Refined product storage at Mesaieed serves domestic distribution and export. Ras Laffan Industrial City — the world’s largest LNG export facility — holds condensate and product tankage integrated into its processing infrastructure, with six LNG berths capable of handling QMax carriers at 266,000 m³ capacity.
8. Egypt — 12–15 Million Barrels
Egypt’s storage position is shaped by its transit corridor role. The SUMED pipeline runs 320 km from Ain Sukhna on the Red Sea to Sidi Kerir on the Mediterranean, supported by tank farms at both terminals with a combined capacity of approximately 12 million barrels. These facilities serve supertankers too large to transit the Suez Canal, making Egypt a critical node in global crude trade flows regardless of domestic production levels.
9. Turkey — 10–12 Million Barrels
Turkey’s storage capacity is dominated by the Ceyhan Marine Terminal on the Mediterranean coast, the export point for the Baku-Tbilisi-Ceyhan (BTC) pipeline and the Iraq-Turkey pipeline from Kirkuk. Tank farm capacity at Ceyhan runs to approximately 6–7 million barrels. Additional commercial and strategic storage at the Kirikkale refinery complex and the Batman terminal in southeast Turkey brings the national total to an estimated 10–12 million barrels.
10. Bahrain — 5–8 Million Barrels
Bahrain’s storage infrastructure centres on the Sitra terminal complex and the Bapco refinery system. The Bapco Modernisation Programme, completed in phases through 2024–2025, added downstream processing capacity and associated product tankage, bringing estimated operational storage to 5–8 million barrels. Bahrain also functions as a regional headquarters for several trading and logistics operators, adding commercial leasing activity to the national total.
The Future of Oil Storage Capacity Middle East: What to Watch in 2026
The strategic direction across the region is consistent: Hormuz-bypass capacity is being built at pace. Oman’s Ras Markaz, the UAE’s underground Fujairah cavern, and Saudi Arabia’s Red Sea tankage are all designed to maintain export capability under geopolitical stress. Commercial storage at Fujairah continues to attract leased capacity from Asian and European traders seeking flexible access to Gulf crude. Iran’s floating storage position — capable of adding 30–60 million barrels to effective regional supply — remains the largest single variable in any assessment of oil storage capacity in the Middle East heading into the second half of 2026.
Which country has the largest oil storage capacity in the Middle East?
Saudi Arabia leads the region with an estimated 150–180 million barrels of operational capacity, anchored by the Ras Tanura export complex on the Gulf and the King Fahd Industrial Port at Yanbu on the Red Sea.
How is oil storage capacity in the Middle East measured and ranked?
Rankings combine strategic petroleum reserve capacity, commercial terminal tank farms, refinery tankage, and fixed offshore loading infrastructure. Floating storage fleets — most relevant to Iran — are excluded to maintain comparability across countries.
What makes Fujairah a significant oil storage hub in the Middle East?
Fujairah sits outside the Strait of Hormuz on the Gulf of Oman, making it a strategically secure commercial storage and blending hub. The port zone holds over 18 million cubic metres of tank capacity, supplemented by a 42-million-barrel underground strategic storage facility.
Why does Iran’s oil storage capacity vary significantly in different estimates?
Iran combines fixed onshore capacity (approximately 70–80 million barrels, primarily at Kharg Island and Jask Terminal) with a large floating storage fleet that adds 30–60 million barrels depending on sanctions conditions and export constraints. Rankings that include floating inventory will show substantially higher totals.
What is the Ras Markaz terminal and why does it matter for regional storage?
Ras Markaz is a large-scale crude storage terminal under development on Oman’s Arabian Sea coast, designed for up to 200 million barrels at full build-out. Its location outside the Strait of Hormuz makes it a significant Hormuz-bypass infrastructure project, attracting leasing interest from Gulf producers seeking alternative export routes.
