Centralization diagram

A secure cement job is the backbone of well integrity. Centralizers keep casing centered in the wellbore while cement is pumped between the casing and the well walls.

Improper casing centralization can result in a poor-quality cement job that threatens well integrity. Off-center casing makes it difficult or impossible for cement to adequately fill annular spaces and create a barrier that protects the casing, prevents water flow, and isolates the producing formation. The right selection and placement of centralizers can improve casing standoff, which enables the slurry to rise uniformly into the annular area for high-quality cementing.

Variform Centralizers
