For horizontal wells with long laterals, tortuous boreholes, and severe well geometries (including high doglegs), our unibody bow spring centralizers are the ideal choice. The one-piece, non-welded construction eliminates weak points, allowing for confident casing string rotation and reciprocation in tight wellbore situations.
During casing rotation operations, these centralizers remain in place while the pipe rotates inside them. This agitation capability during cementing operations improves cement bond and long-term cement integrity.
Unibody bow springs act as semi-rigid centralizers, designed to be slightly under gauge to minimize drag while offering both flexibility and high restoring force. They compress and deform to navigate restrictions, then revert to their original form without permanent deformation.
