Summary:

The pipelining of high paraffin wax crude oils of the Western Kazakhstan during cold winter months is accompanied by deposition of asphaltene and paraffin wax on the internal surfaces of pipelines. This results in narrowing of pipelines and thus reduces production, and necessitates time consuming line pigging and oil-slam utilization. As a rule of thumb, oils are transported using preheating and/or adding pour point depressants. Preheating in Kazakhstan and some other countries is not economically sound especially during high oil prices. Also it is not environmentally friendly procedure because burning oil or gas in the preheating furnaces causes pollution. Using pour point depressants is environmentally friendly way to facilitate oil transportation. From the economical point of view, however, it is comparable to preheating. Physical methods of oil treatment have attracted considerable attention of researchers due to necessity to make oil transportation more economical and eco-friendly. This report demonstrates the effect of magnetic field on the viscosity of different paraffinic oils of Western Kazakhstan. It is shown that the effect depends on the oil compositions and different parameters of oil treatment.
