Who benefits from high oil prices?

 Putin is on a military incursion to take over Ukraine, or at least a portion of it.

Oil futures have been rising uncontrollably, even when oil production hit a record high. 

According to Worldometer.info, the US is pumping out 14 billion barrels per day, Saudi Arabia and Russia right behind it. The US oil industry stands to gain heavily from the Russia-Ukraine conflict. 

On the revenue (minus production costs) side, Saudi Arabia seems to operate most efficiently, accruing revenues of $113bn in 2020. Russia at $72bn and the US at $50bn. Higher prices will increase margins for the US drillers. The same goes for other countries. However, the US has the most to gain from inflation. The production cost cannot be avoided for the US. Saudi Arabia and Russia both have a competitive advantage over production costs. 

Does this mean that the US oil companies have more ways to go?

Exxon Mobil Corp's stock price has gone up 39.25% in 6 months. Can it still go up even higher?

Chevron Corporation improved its stock pricing by 36.88% in 6 months. Are these valuations overreached? or are we going to see more of it as the Russia-Ukraine conflict drags on?
