Abstract:
A stress-free centralizer system for wellbore tubulars having a centralizer portion with hollow vanes or solid vanes. An injectable material can be configured to harden at ambient or elevated temperatures and installed into the hollow vanes while coating a portion of the inner surface of the centralizer portion. Alternatively, a swellable encapsulation and shape shifting material can be used instead of the injectable material. Additionally, primers and adhesives can be used with the centralizer portion. Both materials when hardened or swollen can be configured to withstand temperatures and pressures within a wellbore for twenty-four hours without melting or degrading. The centralizer portion can simultaneously prevent axial movement and rotational movement while installed on the wellbore tubular, distribute load evenly around the centralizer portion, and provide cathodic protection to the wellbore tubular without using a stop collar with screws.

Claim (Index 3):
The stress-free solid vane centralizer system of  claim 1 , wherein the plurality of solid vanes are helically oriented around the longitudinal axis of the solid vane centralizer portion.
