Urengoy gas field
The Urengoy gas field is one of the largest contiguous natural gas reserves in the world at over 300 TCF (= 300 trillion (10¹²) cubic feet or 8.5 trillion cubic meters ) . It is in Russia in the autonomous district of Yamal-Nenets the Tyumen Oblast ( Siberia ) south of the Arctic polar circle .
It was discovered in June 1966 and production started in 1978. From January 1984 onwards, exports to Western Europe began on the Urengoy - Uzhhorod (Ukraine) natural gas route. The formation of the gas field could not initially be explained by basin studies. Between 1995 and 1997 a joint investigation was carried out by the German Institute for Petroleum and Organic Geochemistry with two Russian research institutes. In 1997, Bernhard Cramer provided the explanation for the migration of natural gas dissolved in the groundwater from the south into a 2500 m thick aquifer and an uplift of the overburden in the Cenozoic .
Around 200 billion m³ of natural gas are currently produced annually. Exploration is being carried out by Urengoyasprom , a subsidiary of Gazprom . The city of Novy Urengoy was founded to develop the gas field .
