This article attempts to forecast european (Western and Eastern) natural gas demand an gas supplies up to 2010. It shows that at such a horizon both Norway and North Africa will have substantially increased their gas exports supplied to the European markets while the largest increase in terms of additionnal volumes will comes the former USSR, essentially from Russia. According to this analysis, Russia would be able to produce the required volumes even without putting into production the Yamal Peninsula fields, while the Russian Barentz Sea gas reserves (namely Stockmanovskoye) could be developed by 2005 or even earlier. During the period 1995-2005 only very limited gas exports to Europe would be required from the Middle East gas sources but the first gas pipeline between this region and Europe could begin to operate around 2010. Later on additionnal Middle East gas will be required in order to keep Europe＇s gas supplies in line with the demand.
