Russia, the second largest natural gas producer closely behind the U.S., faces a 
struggle between declining production from ageing fields and new expensive and time 
consuming developments in Northern Siberia and offshore. Russian gas production 
reached a first peak in 1989 when the largest fields passed peak production. Gazprom 
production never reached that level again. Ageing fields force Russia to speed up the 
development of new fields. The developments of Shtokmanskoye in the Barents Sea 
and of other fields in Yamal are delayed. If the gas fields in the Yamal Peninsula 
would be developed in time, they would have produced 310-360 bcm in 2030 
according to Gazprom. But even this will not be sufficient to compensate for the 
decline of ageing current fields. Domestic consumption in Russia and growing demand
from Asia will put increasing pressure on volumes available for export from Eurasia to
Europe in the coming years.
