    Centek Ltd, together with Protech in the US, has introduced the Centek CT (Close Tolerance) centralizers to operations in the Gulf of Mexico. The centralizer system produces cost savings through its robust and flexible single-piece construction, combined with low friction and low drag design. A characteristic of deepwater wells is reduced tolerances, as operators must run casing through an existing casing, and the centralizer must be flexible enough to compress fully to pass through the close restriction, then expand fully back to gauge with no permanent set occurring. Because of the close tolerances involved, the centralizer does not use conventional steel stop collars on the outside of the liner casing. Instead, the end-bands are notched, allowing low-friction composite limiting-blocks to be inserted, ensuring that the centralizer is pulled into the well rather than pushed, reducing drag.
