› Roller/wheeled centralizers are mainly used for high deviated wells and horizontal wells to centralize casing.
› Can remove wellbore cake and improve mud replacement efficiency.
› Provide superior wear resistance and remain functional throughout the life of the well and can aid in
casing/tubing retrieval.
› Smaller roller-contact area reduces the risk of differential sticking and maintains standoff when running
