In the past three months, Tehran has sold almost half the oil it had held in floating storage, which had tied up many of its tankers as it struggled to offload stocks in an oversupplied global market, Reuters said in an exclusive report.
The amount of Iranian oil held at sea has dropped to 16.4 million barrels, from 29.6 million barrels at the beginning of October, according to Thomson Reuters Oil Flows data. Before that sharp drop, the level had barely changed in 2016; it was 29.7 million barrels at the start of last year, the data showed.
Unsold oil is now tying up about 12 to 14 Iranian tankers, out of its fleet of about 60 vessels, compared with around 30 in the summer, according to two tanker-tracking sources.
The oil sold in recent months has gone to buyers in Asia including China, India and South Korea and to European countries including Italy and France, according to the sources and data. It was unclear which companies bought the oil.
Iran is also looking to use the opportunity to push into new markets in Europe, including Baltic and other central and eastern European countries, said separate oil industry sources, though it was not clear if any oil had been sold there.
Tehran scored a victory when it was exempted from the OPEC deal agreed in November to reduce production by 1.2 million barrels per day for six months, an accord aimed at addressing the global oversupply and bolstering low oil prices.
The country successfully argued it should not limit its production which was slowly starting to recover after the lifting of international sanctions in January last year.
