Rigid casing centralizer is used in deviated wells and horizontal wells. There are several blades on the rigid centralizer that can keep casing from contacting the wellbore wall

Roller rigid centralizer which is most suitable for highly deviated wells and horizontal wells has two or three rollers in each blade. It can change slipping friction to rolling friction, so it greatly reduces the friction between casing and wellbore wall and let casing go to desired position smoothly.
 

Rigid centralizers are an integral part of the cementing process. They provide the mechanism that centers the casing in the hole and allows uniform cement flow around the casing to help protect it at all points. Several styles of centralizers are available for matching different well specifications and hole sizes, including turbulence generating designs that help clean the annulus and distribute the cement more evenly and uniformly. All models offer ample clearance for fluid passage and are extra effective in centering the casing, even in highly deviated holes and improve cement flow by reducing the effects of channeling.
