Uzen-Atyrau-Samara (UAS) Pipeline is an oil pipeline in the Russia and Central Asia.[1] The UAS pipeline provides transportation of crude oil to Atyrau and Samara refineries, as well as railway loading points.[2]


The pipeline originates at the Uzen field, Kazakhstan, and terminates at the Caspian port of Atyrau, Kazakhstan, to Samara, Russia.

Project Details

  • Operator: KazMunaiGas (Kazakhstan), Transneft (Russia)
  • Current capacity: 500,000 barrels per day
  • Length: 1,500 kilometers[2] / 932 miles
  • Status: Operating
  • Start Year: 1971 (upgraded 2009)


The UAS pipeline, commissioned in 1971, provided the first major export route for Kazakhstan.[1] It consists of two sections: the Uzen Atyrau pipeline, which originates at the Uzen field in southwest Kazakhstan and transverses 702 km north to the Atyrau port at the Caspian Sea, and the Atyrau-Samara pipeline.

The UAS pipeline was upgraded in 2009.


In July 2004, damage to the UAS pipeline at approximately the 283-km marker resulted in a spill of 2,500 to 3,000 tonnes of crude oil in the Mangistau region.[3]
