It's also interesting to know that Russia could not maintain its production of oil at last year's market price, due to the lack of investment (it had simply become unprofitable). https://ogst.ifpenergiesnouvelles.fr/articles/ogst/full_html...

The war may force Russia to sell their oil to non-Western countries but the crisis helped support oil price and made global investments in O&G profitable for them again (and for every other producers too). Just like with the war in Iraq - which explains why Putin did not oppose the US invasion for long after they realized it would bring enormous profits to Russia.
