Rigid Centralizers

‘NeOz’ Rigid Centralizers are recommended for cased hole applications however they can function equally well in open hole applications. These provide optimum concentricity during casing cementing operations. The design allows cement to completely surround casing in tight casing to formation conditions.

They Rigid Bows reduce drag during the casing running operations.

NeOz has developed the following types of Rigid Centralizers for specific need of various drilling operators.
