Isis controls most of Syria’s oil fields and crude is the militant group's biggest single source of revenue. Here we follow the progress of a barrel of oil from extraction to end user to see how the Isis production system works, who is making money from it, and why it is proving so challenging to disrupt.
"""

"""
Though many believe that Isis relies on exports for its oil revenue, it profits from its captive markets closer to home in the rebel-held territories of northern Syria and in its self-proclaimed “caliphate”, which straddles the border between Syria and Iraq.
"""
"""
Once the oil is refined, it is bought by traders or taken by dealers to markets across Syria and Iraq. At this point, Isis is almost completely disengaged from the trade. About half the oil goes to Iraq, while the other half is consumed in Syria, both in Isis territories and rebel-held areas in the north.
