"The agreement was struck after a short meeting in Qatar, but it came with a significant caveat: Iran and Iraq must also halt production increases. Iraq’s production has soared to record levels as it furiously pumps to generate revenue to fight a war against Islamic State, while Iran is trying to ramp up output now that western sanctions over its nuclear program have ended"
Not likely
Russia can't afford to stop pumping, Venezula is a corrupt mess and any cutback would be pumped, siphoned and sold illegally. Saudi Arabia is running out of cash. Qatar is the only country that can afford to not increase production. No way Iran is going to do shit, they need money and are sitting on enough oil to pump like madmen for 50+ years. Iraq will keep right on pumping also to cut the Saudis throat
It's more likely that WWIII will start and it will be over oil. Of course then, oil will be useless since everybody will be dead
