Jerome,

What will be the impact of Gazprom's declining gas fields on Gazprom, Russia and Ukraine?  I believe many geologists believe that two of Gazprom's 3 "giant" gas fields will go into decline by 2010.

The 3 giants (Urengoy, Yamburg and Mendeleiev) are already declining. Zapolarnoye has covered that. Whether Russian production keeps on increasing depends on how fast they put on line fields like Shtokman, the Yamal fields and a few others. The reserves are still there; the middle term worry is how quickly they come online and, in the meantime, how the available gas is allocated.
