The TUR-SUB is designed to be run in the challenging, close tolerance, under-ream applications found in some of the world’s most challenging offshore fields.
The TUR-SUB is designed to be run in the challenging, close tolerance, under-ream applications found in some of the world’s most challenging offshore fields.
The TUR-SUB’s precise manufacturing and single-piece construction eliminates the risk of failure, ensuring reliable performance in critical wellbore environments. During operations, the TUR-SUB’s design allows the sub body to rotate within the centralizer at minimal torque, with the centralizer fully recessing into the sub body to navigate the tightest restrictions.
The TUR-SUB centralizer’s interlocked band design provides the strength of a single-piece construction, ensuring superior durability. The sub body is designed to meet API 5CT requirements, meet or exceed the host casing’s burst, collapse and tensile ratings, and be threaded to suit the casing string. Additionally, Centek offers the flexibility to tailor sub bodies to meet customer-specific requirements, making the TUR-SUB a versatile and reliable choice for challenging well operations.
Centek has the capability to supply sub bodies tailored to meet customer specifications. Talk to our Product Service Experts for more information.
Centek TUR-SUBs are available in sizing from 9 5/8” through to 17 7/8”.

"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.”
Read more..."Good decision to use the Centeks. Due to the development costs we had to invest more money, but the job went well and the investment was worth the money.”
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"
