Casing centralizer is a mechanical device that secures the casing from contacting the wellbore walls. It is placed at the center of the hole which enhances the efficiency of the cementing. The casing centralizer helps in providing continuous annular clearance around the casing and it allows cement to completely seal the casing to the borehole wall. The casing centralizer is an important element in ensuring the quality of cementing by preventing mud channeling and poor zone isolation.  

There are four types of casing centralizer, and bow spring and rigid blade types are deployed in any casing size, grade or thread. This factor has increased the adoption of such casing centralizer in the upstream operations in oil and gas industry. The major advantage of casing centralizer is protection of casing string and reduces drag when running casing. 

The use of different type of materials is to ensure the safety and successful cementing operations. The deployment of carbon-fiber ceramic-composite casing centralizer bonded directly to casing with adhesion and the blades are truly integral to the pipe. The advancement in casing centralizer such as isolizer centralizer is used for tight-tolerance applications. It is an alternative solution to conventional centralizer. Such advanced products are getting deployed in challenging wellbore configurations such as deep water, under-reamed holes, and tight tolerance wells. These type of products can be installed on any grade of casing including corrosion resistant alloys, and are deployed in high temperature environment.
