This pipeline links oil reserves in western Kazakhstan to the Black Sea, providing access to world markets. The CPC crude pipeline system is the largest operating investment project with foreign participation on the territory of the former USSR. The length of the main pipeline that connects the oil fields in Western Kazakhstan with the new Marine Terminal in Russia is 1,510 km.
