Viscosity reducers modify the physicochemical properties of heavy crude oil, facilitating its transportation; this, in turn, results in a decrease in cohesion between molecules and allows the heavy crude oil to flow easily through pipelines and processing equipment, which not only simplifies operations but also reduces the costs associated with handling heavy crudes.	cache/cet-15413.pdf	txt/cet-15413.txt
