All crude needs refinement. Cost of transportation, and how much cost of refinement is saved by higher quality crude would be the relevant economic factors.
Here are a couple of excepts from the link below:
"In recent weeks, some wealthy smugglers have begun using "mobile refineries" stationed on trucks to process crude into fuel and other products. Costing up to $230,000, a medium sized mobile plant can refine up to 200 barrels a day. Fuel smuggled into Turkey sells for roughly 50 percent more than in Syria."
"The illicit oil business has a direct health impact too, residents say. The primitive distillation tanks which have sprouted across the province create a blanket of black smoke over villages, causing breathing problems."
"A resident called Nour said that some people are burning the oil to refine it. "There are many diseases appearing. Some people are now covered with boils. They do not wear anything for protection, they even smoke cigarettes while they are doing it."
