In this research, pour point and rheological experiments were carried out on three different crude oils those doped with pour point depressant. It was observed that when the amount of pour point depressant was increased from 500 to 2,000 ppm, pour points of all the crude oils were decreased considerably. In rheological experiments, shear rate versus shear stress values were obtained for all the crude oil samples with and without additives. It was observed that the Bingham Plastic model excellently fit the experimental data with the correlation coefficient > 0.999.
