This is a few years old so let's not get hung up on $ costs, just the underlying conditions.
Russia is one of the most expensive places in the world to produce oil, new analysis produced for Saudi Arabia’s state-owned oil giant Saudi Aramco has found.
The cost of producing a single barrel of Brent crude oil came in at around $42 for Russian onshore projects, and $44 for offshore projects, IHS Markit estimated. That was more than twice the $17 per barrel production costs in Saudi Arabia — the cheapest in the world.
Brent crude is currently trading at $62.40 a barrel on the world markets.
Thin margins with which to rebuild a destroyed military. lol
