Baku-Tbilisi-Ceyhan pipeline

Read more about the pipeline spanning three countries from the Caspian Sea to the Mediterranean coast

Baku-Tbilisi Ceyhan (BTC) pipeline carries oil from the Azeri-Chirag-Deepwater Gunashli (ACG) field and condensate from Shah Deniz across Azerbaijan, Georgia and Turkey. It links Sangachal terminal on the shores of the Caspian Sea to Ceyhan marine terminal on the Turkish Mediterranean coast. In addition, crude oil from Turkmenistan continues to be transported via the pipeline. Starting in October 2013, we have also resumed transportation of some volumes of Tengiz crude oil from Kazakhstan through the BTC pipeline.


The pipeline that became operational in June 2006 was built by the Baku-Tbilisi-Ceyhan pipeline company (BTC Co) operated by BP. The pipeline buried along its entire length is 1768km in total length: 443km in Azerbaijan, 249km in Georgia, and 1,076km in Turkey The Azerbaijan and Georgia sections of the pipeline are operated by BP on behalf of its shareholders in BTC Co. while the Turkish section is operated by BOTAS International Limited (BIL).


The diameter of the pipeline is 42 inches throughout most of Azerbaijan and Turkey. In Georgia the pipeline diameter is 46 inches. The pipeline diameter reduces to 34-inches for the last downhill section to the Ceyhan Marine Terminal in Turkey. Throughput capacity – one million barrels per day from March 2006 to March 2009. Since March 2009 it has been expanded to 1.2 million barrels per day by using drag reducing agents (DRAs).


On 11 August 2014, BTC celebrated the loading of the 2 billionth barrel of oil at the Ceyhan terminal in Turkey. The BTC pipeline passes through 13 districts in Azerbaijan: Garadagh, Absheron, Hajigabul, Agsu, Kurdamir, Ujar, Agdash, Yevlakh, Goranboy, Samukh, Shemkir, Tovuz, Agstafa; 7 in Georgia and 9 in Turkey.


In the first half of 2021, BTC spent more than $69 million in operating expenditure and more than $12 million in capital expenditure.

Since the 1,768 km BTC pipeline became operational in June 2006 till the end of the second quarter of 2021, it carried a total of 3.66 billion barrels (more than 488 million tonnes) of crude oil loaded on 4,796 tankers and sent to world markets.

In the first half, around 99 million barrels (more than 13 million tonnes) BTC-exported crude oil was lifted at Ceyhan loaded on 137 tankers.


The BTC pipeline currently carries mainly ACG crude oil and Shah Deniz condensate from Azerbaijan. In addition, other volumes of crude oil and condensate continue to be transported via BTC, including volumes from Turkmenistan, Russia and Kazakhstan.
