Only thing IRAN has is 30,000,000 million barrels in floating storage. Which they will probably sell 500,000 barrels per day over a 60 day span. They aren't dumb and they don't want to crash the market either.
I think they can only increase their daily production by about 1,200,000 million barrels. It will take them 18-24 months to modernize their oil fields with new technology.
