My thinking is that if the EU has to back down from the price cap due to the effects on their economy, Russia can dictate terms on restarting the oil deal, which I would assume would cover the fines from the breaches of contracts and other compensation. It comes down to who blinks first. Also, OPEC could also tighten the supply even more.

also, I did not know about the oil industry and the effects of stopping the oil drilling. thanks for the info :)
