What will Iran do after it runs out of space to store its crude oil in 22 days?

Iran is running out of space to store its crude oil, with just 12 to 22 days of unused storage capacity remaining. After cutting 2.5 million barrel/day production since the start of war, Iran may cut output by another 1.5 million barrel/day by mid-May. US naval blockade has prevented two million barrel/day of Iranian oil from entering the world's markets.
