Kirkuk–Ceyhan Oil Pipeline

Overview

The Kirkuk–Ceyhan Oil Pipeline, also called the Iraq–Turkey Pipeline, is a system of two large oil pipelines built to carry crude from northern Iraq across Turkey to the Mediterranean export terminal at Ceyhan. Jointly owned by Iraq and Turkey under international agreements, it connects the oil fields around Kirkuk and the Kurdistan Region to international markets. The route is a major outlet for northern Iraqi oil and a source of revenue for Iraq’s economy. Its control became a central issue in the struggle between the federal government in Baghdad and the Kurdistan Regional Government over oil sales and their proceeds.

The disagreement reached a turning point in March 2023, when an international arbitration ruling led Turkey to halt pipeline operations and the loading of Kurdistan Region crude at Ceyhan. Nearly 500,000 barrels per day in exports stopped. After more than two years, an agreement facilitated by the United States brought Baghdad, officials in Erbil and international oil companies into a new export process. Iraq’s federal oil organization exclusively markets northern crude shipped through the reopened route.

Background

Iraq and Turkey signed the original pipeline agreement in 1973 and revised it in 1976, 1985 and 2010. The agreement requires Turkey to follow instructions from the Iraqi side concerning Iraqi crude moving through storage facilities and the Ceyhan terminal. Its 2010 extension defines the “Iraqi side” as Iraq’s federal Ministry of Oil and applies that definition to earlier pipeline documents. This provision became decisive when Turkey permitted exports arranged by the Kurdistan Regional Government without federal authorization.

The dispute developed without a national Iraqi hydrocarbon law assigning responsibilities between Baghdad and the Kurdistan Regional Government. After a federal oil bill stalled in 2007, the regional government enacted its own oil law and began signing production-sharing contracts. Baghdad and Erbil developed competing approaches to oil contracts, exports and revenue. The Kurdistan Regional Government also sought to replace federal budget transfers withheld by Baghdad with income from direct sales.

The regional government signed a long-term oil agreement with Turkey and built a domestic pipeline connecting to the Iraq–Turkey system at Faysh Khabur, on the border. In early 2014, Turkey began permitting Kurdistan Region crude to move through the system independently of Iraq’s federal Oil Ministry. Oil shipped through Ceyhan reached international markets by May. Pipeline access allowed the regional government to sell crude directly and collect the proceeds, while the federal government maintained that Turkey needed its authorization for transport, storage and loading.

Export dispute and shutdown

In May 2014, Iraq’s State Oil Marketing Organization filed an International Chamber of Commerce arbitration claim against Turkey. The claim challenged Turkey’s transport, storage and loading of Kurdistan Region crude at Ceyhan without federal Oil Ministry permission. Turkey’s state-owned pipeline operator, BOTAŞ, represented the Turkish government in the proceedings. The case concerned the obligations of Turkey under the bilateral pipeline agreement as well as the competing export policies that had emerged within Iraq.

The Kirkuk fields made the dispute over northern oil especially consequential. Following the 2017 Kurdistan Region independence referendum, Iraqi forces took control of Kirkuk from the Kurdistan Regional Government, cutting off a major source of regional oil revenue. Weeks later, Iraqi Prime Minister Haider al-Abadi visited Turkey and opened talks on replacing the damaged Kirkuk–Ceyhan pipeline. In February 2022, Iraq’s Supreme Court declared the Kurdistan Region’s oil and gas law unconstitutional, intensifying the dispute over regional exports.

On March 25, 2023, the International Chamber of Commerce issued its ruling in Iraq’s arbitration against Turkey. The decision produced a binding award of $1.46 billion plus interest to Iraq for part of the 2014–2018 period. Claims concerning 2018–2023 and some earlier periods remained for later decisions. Turkey then stopped operating the pipeline and loading Kurdistan Region crude at Ceyhan pending Iraq’s permission. Turkey subsequently sought further concessions from Baghdad and Erbil before reopening the route.

The closure stopped nearly 500,000 barrels per day in exports: about 420,000 barrels marketed by the Kurdistan Regional Government and 80,000 by Iraq. At the time, the route was the Kurdistan Region’s only oil export outlet. The stoppage eliminated almost all regional government income, and interruptions had cost it more than $7 billion by late 2023. Production in northern fields fell sharply as companies faced uncertainty over recovering operating costs; the disruption also deterred investment. During the closure, the regional government raised production to about 200,000 barrels per day, most of it for domestic use.

Outcome

A United States-facilitated agreement among Baghdad, Erbil and international oil companies enabled exports to resume after more than two years. Under the new commercial process, Iraq’s federal oil organization exclusively markets northern crude carried through the reopened pipeline. The arrangement addressed Baghdad’s contractual authority over exports while restoring a route essential to the Kurdistan Region’s oil industry and revenue. Reopened flows initially remained below the pre-closure level of roughly 400,000–450,000 barrels per day.

Aftermath and legacy

The first cargoes after reopening went chiefly to Mediterranean and European refiners. The tanker Seaways Brazos later loaded about one million barrels of northern Iraqi crude at Ceyhan and sailed to Louisiana. On November 24, a tanker carrying Kurdistan Region crude exported through Ceyhan delivered its cargo to the Louisiana Offshore Oil Port. The shipment demonstrated the restored route’s reach beyond the Middle East.

The pipeline remains important to Iraq’s economy because it provides northern fields with access to Mediterranean shipping and foreign buyers. Renewed exports support economic cooperation with the United States and give Iraq another means of strengthening its own energy sector against the influence of the Iranian regime. The shutdown showed how strongly the Kurdistan Region’s finances and oil investment depend on uninterrupted access to Ceyhan, while the arbitration established that independent shipments through the bilateral pipeline could not bypass Iraq’s federal authority without consequences.
