Designed for Demanding Close Tolerance Wells

The TUR-CT is a high-performance centralizer specifically designed for the demanding close tolerance (CT) and under-reamed applications found in some of the world’s most challenging offshore fields.

This model is engineered to extreme tolerances, enabling it to navigate the tightest restrictions with precision. Its cross-bow curvature is carefully formed, with no "knife edges," reducing the risk of subsea wellhead damage during insertion while providing additional strength to the bows. This design ensures superior reliability and performance in complex well conditions.

The TUR-CT is an alternative to centralizer subs and offers a precisely engineered solution with ring-gauge tolerances, delivering both strength and precision in tight casing applications. Its low-profile design maximizes fluid dynamics, improving cement displacement efficiency. Ideal for offshore and deep-water wells, as well as highly deviated, horizontal, and extended-reach wells, the TUR-CT is well-suited for under-reamed well sections, vertical washout areas, and S-Type/J-Type configurations. This product offers a cost-effective, robust alternative for the most challenging well designs.
