Ras Tanura and Abqaiq: the terminal, the refinery and the attacks

Where is Ras Tanura?

Ras Tanura is on a sand-spit peninsula on the Saudi coast of the Persian Gulf, in the Eastern Province, about 25 km north of Dammam and about 60 km north-west of Bahrain's capital, Manama. The tip of the spit, officially Ras Tanura, carries the oil terminal: a tank farm, two piers and, about a mile beyond the northern one, the Sea Islands. The refinery and the town sit further up the peninsula. Britannica describes it as a principal Persian Gulf terminal of the pipelines, with a port that can take the largest tankers (Britannica).

The refinery, the terminal and Ju'aymah

Aramco's port book, Ports and Terminals, 2025 edition, lists the crude grades loaded at Ras Tanura as Arabian Extra Light, Arabian Light, Arabian Medium and Arabian Heavy, plus gas condensate.

How big is Ras Tanura?

The numbers in circulation measure different things, at different dates, and some have no source. This is what each source actually says.

A line that turns up on reference pages, and in the AI answers that quote them, says Ras Tanura handles about a fifth of the world's oil exports. We found no EIA or Aramco figure that says so. EIA's own measure is a handling capacity: about 6.5 million barrels a day for the whole port, in a 2017 brief (EIA).

The refinery's age depends on which line of Aramco's history you read. A 3,000-barrel-a-day 'tea kettle' refinery opened in 1941 and closed six months later because of wartime shortages. Aramco dates the main refinery to 1945, while noting that the war ended before it began operating, and gives 1947 as its first full year, at 50,000 barrels a day (Aramco history). The first crude cargo was loaded at Ras Tanura on 1 May 1939, when King Abdulaziz opened the valve to the tanker D.G. Scofield (Aramco).

Abqaiq: where Saudi crude is processed

Abqaiq is inland, about 90 km south-west of Ras Tanura. It is not a port or a refinery. EIA describes it as Saudi Aramco's largest oil processing facility and crude stabilisation plant, where most Saudi oil is processed before it is exported or refined, with pipelines to Jubail and Ras Tanura (EIA, 2017). In 2019 EIA put its capacity at 7 million barrels a day, about 7% of the world's crude production capacity (EIA).

Abqaiq is also where Saudi Arabia's way round the Strait of Hormuz begins. The East-West pipeline carries 5 million barrels a day from Abqaiq to Yanbu on the Red Sea, and was expanded to 7 million temporarily in 2019 (EIA).

The attack of 14 September 2019

Drones and missiles hit Abqaiq and the Khurais oil field. Aramco said the fires suspended 5.7 million barrels a day of crude output (Aramco). The Houthis claimed the attack; Saudi Arabia and the United States blamed Iran, which denied it (BBC). A UN panel of experts later found the Houthis unlikely to be responsible, because the weapons' range did not allow a launch from territory they held (UN, S/2020/70).

Three days later Aramco said Abqaiq was back at 2 million barrels a day, with the lost output to be restored by the end of September (Aramco).

Attacks on Ras Tanura and Abqaiq, and who said so

Claims, Saudi statements and news reports often disagree on what was hit, by what and by whom. Each row keeps the speaker.

Saudi statements on the 2021 and March 2026 attacks named no attacker. Some summaries call the March 2026 attacks Iranian-linked; the ministry statements quoted here do not. The Houthis claimed attacks on Saudi oil sites from July 2026 onwards.

Ras Tanura and the Strait of Hormuz

A tanker loading at Ras Tanura has one way to open water: down the Gulf and through the Strait of Hormuz. In 2024 Saudi Arabia shipped 5.5 million barrels a day of crude and condensate through the strait, 38% of the crude that crossed it (EIA).

When the war began on 28 February 2026, the way round mattered. Aramco said it ran the East-West pipeline at its 7 million-barrel maximum in the first quarter, to export more from the west coast (Aramco). EIA estimates the line was carrying more than 5 million barrels a day of exports through Yanbu before attacks on it in September (EIA).

Yanbu's cargoes still have to leave the Red Sea, through Bab el-Mandeb or Suez, and on 20 July 2026 the Houthis declared a blockade of Saudi shipping. The bypass moved part of the risk to another chokepoint.

Ras Tanura from space: what the satellites showed in 2026

Sentinel-2, the European Union's free Copernicus imaging satellites, photographs Ras Tanura every few days at 10 metres per pixel, and the sky over the Gulf coast is often clear. That is enough to show a tanker alongside a berth as a long pale hull, and not enough to show a name, a cargo or how full the tanks are (ESA).

7 NOV 202512 NOV 2026

A year apart, the berths look much alike. The year in between did not. Bloomberg reported that no crude loadings were seen at the terminal from early March 2026, and Reuters that they resumed on 26 June. The Sea Island, where the large tankers berth, tells the same story.

On all 14 clear passes from 7 March to 22 June 2026, no large tanker was moored at the Sea Island. A smaller vessel, about 100 metres long, lay beside its middle platform in mid-June. The North Pier, which loads products only, still had a ship alongside on several of those passes. The pictures agree with the reports. They do not prove them, and they say nothing about how much oil was loaded.

What these pictures can and cannot show

• Can show: a large hull alongside a pier or the Sea Island at the moment of the pass, and the layout of the piers, the Sea Island and the tank farm.
• Cannot show: barrels, how full a tank is, which grade is loading, whether a refinery unit is running, or who fired at it.
• Cannot see through cloud: Sentinel-2 is an optical camera. Ras Tanura is often clear, but not always.
• Not a count of the port: one picture is one moment. A berth empty at 07:30 UTC may be busy by noon.

Pictures of Ras Tanura reach the public Sentinel-2 catalogue about five hours after each pass, the median of the passes we checked from June to November 2026. An EU Council decision of July 2026 to delay Sentinel data by 24 hours covered an area of the Gulf of Oman east of 59.6 degrees east, far from Ras Tanura and Abqaiq, and the Official Journal declared its publication null and void on 29 July (corrigendum).
