CPC, which handles about 1% of global oil, also said it shipped 58.7 million tonnes in 2022, including 52.2 tonnes from Kazakhstan.

The consortium, which delivers oil from Kazakhstan via a Black Sea terminal, last year faced maintenance issues at the terminal and oil fields, including Tengiz, the key source of oil for CPC.

Kazakhstan is the second-biggest oil producer among the ex-Soviet countries after Russia, pumping around 1.5 million barrels per day, and both countries are members of the OPEC+ group to coordinate oil production.

The main CPC shareholders are Russian oil pipeline monopoly Transneft with 24%, Kazakhstan's KazMunayGas (19%), Chevron Caspian Pipeline Consortium Company (15%), LUKARCO B.V (12.5%), Mobil Caspian Pipeline Company (7.5%), CPC Company (7%) and Rosneft-Shell Caspian Ventures Limited (7.5%).
