As of 1 January 2018, over the course of cooperation over 129.56 bcm of gas has been supplied to Romania, including 1.19 bcm in 2017.

Romania also plays an important role in the Russian gas transit to Bulgaria, Turkey, Greece and Macedonia.

The gas cooperation with Romania began with the development of the Orenburg gas condensate field and construction of the Orenburg – Western Soviet Border gas pipeline, as established in the General Agreement between member states of the Council for Mutual Economic Assistance of 1974.

Russian natural gas has been supplied to the country since 1979, and its share on the Romanian market has varied from 2% to 25% of total consumption. Gas supplies from the Russian Federation are performed under long term contracts concluded with the companies Gazprom Schweiz AG (WIEE AG) and Conef Energy for natural gas supplies to Romania through 2030.
