Rheological properties of asphaltene-resin-paraffin sediments (ARPS) are shown depending on content of resinous components in crude oil. The results of experimental studies on low-paraffinic, high-paraffinic oil show that the presence of asphaltenes and resins in the oil dispersion system can lead to depressant effects. According to the obtained results, it was found that asphalteno-resinous components are natural depressants that reduce the temperature of wax crystallization in oil, and their depressant properties depend on the type of oil. The following types of additives were studied as additives in the work – Difron 4201 and BAF-1. It also follows that the greatest decrease in oil viscosity is observed in the presence of BAF-1 additive.
