The UROS-SUB centralizer is designed to be run in the close tolerance, under-ream applications found in some of the world’s most challenging deepwater wells.
The UROS-SUB centralizer’s single-piece design minimizes the risk of failure in high-risk wellbores, while allowing the centralizer to rotate on the sub body with minimal torque. This innovative solution is built to perform under extreme conditions, with the centralizer recessing into the sub body during run-in-hole (RIH) to pass through the tightest restrictions.
Key benefits of the UROS-SUB centralizer include its suitability for ultra-tight tolerance applications and a low equivalent circulating density (ECD) profile to minimize surge effects during RIH. The design enables rotation when fully compressed and features fewer bows for more efficient RIH performance. The interlocked band design combines the strength of a single-piece centralizer with optimized RIH performance.
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.
Centek has the capability to supply sub bodies tailored to meet customer specifications. Talk to our Product Service Experts for more information.
Centek UROS-SUBS's are available in sizing from 9 5/8” to 17”.

The UROS centralizer features a patented offset bow design that significantly reduces starting and running forces in wells with under-reamed sections.
UROS Under-Ream Offset Bow Spring Centralizer
The UROS-CT is designed to be run in the close tolerance, under-ream applications found in some of the world’s most challenging offshore fields. This close tolerance (CT) model is engineered to extreme tolerances enabling it to negotiate the tightest restrictions.
UROS-CT Close Tolerance Under-Ream Offset Bow Spring Centralizer
"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.”
