Choose the Right Type of Centralizer

Jun. 28, 2018

In any wellbore, it is critical to choose the right type of centralizer and to place those centralizers at optimum position on the casing to achieve good and consistent standoff. Casing centralizers are available in many shapes and sizes. It is important to understand the differences in each type and which is best suited to each application. 

Centralizers are used to keep the casing from contacting the borehole, while providing a good standoff clearance around the casing to aid running and cementing operations. In horizontal wells, centralizers need to have a high restoring force to support the weight of the casing, and a low running force to reduce drag. They also need to allow pipe rotation and reciprocation to aid in the casing running process, reduce differential sticking tendencies, and improve mud flow and zonal isolation while cementing.
