UPDATE 1-Russia mulls oil output cut, no decision yet -energy minister

Before OPEC meets next week, Russia has already spoken to members Venezuela and Saudi Arabia about the need to support the oil market, and Moscow expects to send a high-ranking delegation to Vienna before the meeting to press the message on prices.
Russia's already weak economy has been hit by the falling price of oil, which together with natural gas generates half of state revenue.
