Abstract

This study investigated the effect of different percentages of microwax on the viscoelastic profile of crude oil samples. The viscosity results agreed with the literature and revealed increased viscosity with higher amounts of wax. However, during the oscillatory tests, no significant differences in viscoelastic behavior were observed between the samples, even when fully crystallized. Furthermore, all samples exhibited nearly identical stresses during yield stress analysis. Gelation temperature varied between the samples, as did WAT, as identified by DSC. These findings highlight the complexity of the interactions between wax and the crude oil’s viscoelastic properties, emphasizing the importance of a comprehensive analysis to fully understand its behavior under different conditions.
