The BTC pipeline is used to export oil from the Azeri, Chirag and Guneshli (ACG) oilfields operated by BP.

Export volumes through BTC declined to 27.5 million tonnes during the whole of 2017 from 28.8 million tonnes in 2016.

Azerbaijan also exports oil via Russia through the Baku-Novorossiisk pipeline and via Georgia by rail and through the Baku-Supsa pipeline.

Oil from Kazakhstan, Turkmenistan and Russia is also exported through the BTC pipeline.
