It seems Russia's not quite as flush with oil as they hoped.
http://news.bbc.co.uk/2/hi/business/7348463.stmMany of their oilfields are becoming exhausted, and they are finding it difficult to find investors to tap new oilfields further afield. All that capital flight can't have helped. There are problems keeping abreast of demand and with accessing existing supplies.
This is bad because Russia ia a major source of oil for us in Europe, despite all out efforts to diversify.
It is good because Russia will be far less inclined to play politics with their oil trade. While Putin has insisted that Europe is vital to their trade, he is more than capable of tinkering with the pipes for his own ends. This will become less of a threat. Also, Russia's oil industry needs funds and Europe has been the traditional investor over there. If he wants our investment he'll have to keep us sweet. Recently the EU signed a deal with Turkmenistan, looking to buy some of their oil. While unimportant immediately (we have no way of actually getting their oil) it will be a further reminder to Russia not to take us for granted.
VenezuelaIn other oil news, Venezuela is increasing taxes on foreign oil companies in an attempt to further control their monies.
