Iran produced 3.795 million barrels per day of oil in May, an increase of 4,000 bpd from 3.791 million bpd in April, the Organization of the Petroleum Exporting Countries (OPEC) announced in its monthly report released on Tuesday.

Iranian oil export to Turkey increased more than two times to 211,101 barrels per day during the first quarter of 2017 compared to the same period last year.

Iran's oil exports to the West surged in May to their highest level since the lifting of sanctions in early 2016 and almost caught up with volumes exported to Asia, a source familiar with Iranian oil exports said.
