Other Information

  • Approximately two-thirds of the liquids produced are stabilised at the Karachaganak Processing Complex (KPC) – with a capacity of over 150,000 barrels/day – before they are sent to western markets through the Caspian Pipeline Consortium Oil Pipeline and, since 2006, also through the Atyrau-Samara pipeline, which is connected to the Russian export system. The non-stabilised liquids and the gas that is not re-injected into the deposits are sold on the local Russian market through the Orenburg terminal.
