Oil market sources say Iran has sold all the oil it had stored at sea for years – a sign of the country’s positive performance in marketing its vital crude oil supplies.

The recent reports indicate that the Islamic Republic of Iran has already been able to escalate its oil exports to levels that existed before sanctions were imposed on the country in 2011.

A Reuter’s survey estimates that Iran’s crude oil production rose by 10,000 bpd (barrels per day) to 3.77 MMbpd (million barrels per day) in March 2017—compared to the previous month.
