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.
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.

"The side track was run successfully with no issues. We would use Centek products again, this time in the first instance."
Read more..."No issue at all to get casing to the bottom…managed to rotate while cementing approximately 20rpm, 10-15kft lbs torque. Will be using the same for the next 2 wells"

"The Centek UROS-CT centralizers performed perfectly, allowing us to reach TD smoothly with tight clearances and no drag-related problems.
The cement bond log confirmed a good cement job, and overall borehole stability remained excellent throughout the operation. This equipment combination played a key role in achieving a successful, trouble-free liner run.”
