FACTBOX: Russian gas export pipelines, projects

(Reuters) - European countries faced reduced gas supplies at the height of winter on Monday after Russia halted deliveries to Ukraine over a price dispute last week.

Russia's gas monopoly Gazprom supplies one quarter of Europe's gas needs.

This is how the gas gets to Europe from Russia and some of the new pipeline projects aimed at bringing more Russian gas to Europe and diversifying supplies.

* Eighty percent of gas bound to Europe travels via Ukraine. Russia says Ukraine is tapping gas earmarked for Europe and that Ukraine had shut down a pumping station supplying gas to the Balkans.

* Germany and Poland can also get gas via the Yamal pipeline which crosses Belarus. Its capacity is 30 billion cubic meters (bcm) a year compared to 120 bcm via Ukraine. Gazprom has increased exports through Yamal to help compensate for lower flows through Ukraine.

* The third export route is the Blue Stream pipeline, which runs from Russia to Turkey under the Black Sea. Gazprom said it was supplying additional gas through the Blue Stream pipeline as well as from its reserves in European underground storage.

PIPELINE PROJECTS

* YAMAL-EUROPE PIPELINE - The pipeline, which runs from the Yamal peninsula in Russia's Arctic north to Frankfurt on Oder on the Polish-German border, carries Russian gas for over 4,000 km (2,485 miles). The expansion of the pipeline, which is expected to be completed by 2010, should boost capacity to 67 billion cubic meters of gas a year through two stretches.

* GALSI PIPELINE - The 910 mile (1,350 kn) Galsi gas pipeline could bring up to 10 billion cubic meters a year of Algerian gas to Italy through Sardinia when it opens in 2012. Italy is pushing the developers, including state-run Algerian gas company Sonatrach and Italy's Enel, to finish the project before then.
