In this work, a Drag Reducing Agent (DRA) has been employed to reduce the drag of Iraqi crude oil using Poly Vinyl Pyridine (PVP) at different concentrations (0, 500, 750, 1000, 1250 and 1500 ppm). Results show that a significant decrease in flow index values has been achieved at a concentration range of (750-1500 ppm) in which the lowest value is obtained at a PVP concentration of 1000 ppm. This has been clarified by obtaining flow indexes of less than unity indicating the sample shear thinning. Thus, using a DRA concentration of 1500 ppm decreases the pressure drop by 35.7 % for a pipeline capacity, pipe diameter and length of 0.02 m³/s, 0.0508 m and 10 m, respectively. In addition, a maximum drag reduction of 35.1 % has been achieved at the highest concentration (1500 ppm). Therefore, the DRA addition saves the pumping power and increases the produced flow by 35.1 % and 27.5 %, respectively.
