Right after the news on the framework agreement on Iranian nuclear program, the oil prices in the world market collapsed. Thus, according to Bloomberg, the price of Brent Crude oil fall by $2.15 reaching to $54.95 a barrel.
As for the release of the Iranian oil and gas to the world market, then, according to The New York Times, it would take Tehran at least a year. And even in this case, it is unlikely that Iran until the end of 2016 will increase oil production by more than half a million barrels a day as today oversupply of oil is estimated as nearly 2 million barrels a day.
In 2014 Iran's oil exports amounted about 1.2 million barrels a day. In the case of lifting the sanctions, Iran could also use the oil accumulated in storage.
