//The low price of oil which is harming the Russia economy is the result of Saudi Arabia over producing.//
The Saudis have not been 'over producing' but they have refused to cut production. The Americans are not buying oil on the world market, being self sufficient since their fracking programme in the States and the development of the Alaskan oil fields, so the demand for oil has reduced bringing down the prices. The Saudis cannot just turn off the taps due to the technical issues, neither do they need to do so, because their production costs are much lower than every other producer, they can ride the low price storm. But if the Russians can disrupt the supply lines, or destroy enough oil producing facilities, the price will rise to a level that makes their own oil and gas production viable again. An even worse case scenario is that China, being happy with low priced oil, intervenes if it feels the prices are likely to affect them unduly.
