THE ISLAMIC STATE’S OIL BUSINESS: A detailed analysis of Islamic State oil production, from the last six months of 2014 to this year.

How much ISIL received per barrel from the brokers and smugglers became known gradually as information could be extracted from those sources. It apparently averaged about $25 per barrel meaning that ISIL obtained about $40-45 million a month in 2014 from this source. In 2015 that fell to $20-30 million and in 2016 it was $10-15 million in 2016. In 2017 it was down to $5 million or less per month and this decline was verified by ISIL prisoners, defectors and deserters through that period as well as data provided by civilians escaping ISIL controlled territory as well as those few who managed to use cell phones or Internet access to communicate from ISIL territory in that period.

These economic woes played a major role in ISIL losing control of the territory it ruled during that period.
