Since sanctions were lifted in early 2016, Iran has sharply increased its oil production (CNN Money), and the country is aiming to hit a rate of 4 million barrels per day in the near future (PressTV). Question will be resolved using monthly data for "Iran, I.R." reported in the "OPEC crude oil production based on secondary sources, tb/d" table of the "World Oil Supply: OPEC Crude Oil Production" section of OPEC's Monthly Oil Market Report.
