Bow Centralizer is used for casing the center of a well bore or during a cement job. It is a metal strip shaped like a hunting bow and attached to a tool or to the outside of casing. It is a critical step in quality cementing as the lack of proper centralization can lead to severe cementing problems including lack of zonal isolation and improper casing support. Bow Centralizer allows the cement to be evenly distributed around the casing string.
