The wax deposit causes flow problems in oil poduction and production and transportion. Visocity's of waxy crude oil in presence and absence of sufactants mixture have been measured at wax content between 9-28%, temperature between 45?C and 65?C shear rates ranging from 30 to 300s-1. The behaviors of waxy crude oil before, during and after an application of shear force have been studied. The results of this study reveal that the viscoity of the waxy cude oil decreases as the temperature increases. The results also indicated that the rheological behaviour of waxy crude oil at low concentration of wax and disperstants. In additions
