Russia really needs to get their other brand of goods (besides resources) on the market. Real potential is its energy industrial goods (Rosatom and Power Machines), high tech, CNC and automotove. Hopefully it is those goods that will have big returns for Russia in long run after decades as that equipment will need to be replaced and people already trained on Russian gear will be inclined to buy Russian goods again (As example is defence industry with accordance to many former USSR allies).
As well, maybe this will reduce cost of fuel in Russia for average driver.
Thats 180 000 000 barels per year = 19.2 bin $ per year at 107$ per barel and thats a fricking lots of money that can buy lots of machinery and weapons and
products like planes or even entire factories. It could be that Russia will get that oil on a more privileged price and the total sum of money will be less but
nevertheless it is still big amount of money.
