The heavy and extra heavy crude oil from all over the world possess the non-Newtonian flow behavior which results in serious problems related to its transportation from oil fields to refineries. The rheological behaviors of synthetic oil with or without surfactants were studied in the present work. Synthetic oil was prepared by mixing heavy paraffin and mineral oil in different proportions. Anionic surfactant SDS (sodium dodecyl sulfate), cationic surfactant CTAB (hexadecyltrimethyl ammonium bromide) and neutral surfactant Brij S-20 (polyethylene glycol octadecyl ether) were used. Experimental measurements were carried out by physica MC01 Rheometer. Effect of several parameters like shear rate, temperature and addition of mineral oil on viscous behaviors had been studied. US200 software package was used to measure desired parameters. The experimental results showed that viscosity of synthetic oil decreased with increasing temperature b
