Frtom Amir: " "Powerful Sunni Muslim tribes have deployed armed fighters around oil production facilities and pipelines that have fallen under their control and set up smuggling and trade deals, according to sources in the province including rebels, an oil company employee and people with ties to the tribes." "Thousands of barrels of crude are smuggled to Turkey daily by small tankers using farm roads, said Abu Ramzi. The oil is taken to the Bab al-Hawa or Tal Abiad border posts, a source close to the smugglers in Deir al-Zor said. The price of a barrel depends on the quality of the crude oil and the cost of transport - the shorter the trip the cheaper - but it could be 8,000 Syrian pounds, slightly over $50, he said."
