TUR-SUB Centralizer Sub

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.

TUR SUB Wide

Precise Manufacturing Eliminates Risk of Failure

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.

In tight annulus applications and deep-water operations, centralizers must compress virtually flat to allow travel through narrow under-reamed well sections.

Precise manufacturing and the TUR SUB’s single piece constructions eliminates the risk of failure associated with welded bow spring centralizers. This integrity and strength allow the sub body to rotate within the TUR centralizer at minimal torque values.

During operations, the TUR centralizer will recess entirely into the sub body enabling it to pass through the tightest of restrictions. The sub body is manufactured to API 5CT requirements and will meet or exceed burst, collapse and tensile ratings and will be threaded to fit the casing string. 

Centek has the capability to supply sub bodies tailored to meet customer specifications.

Key Benefits

  • Designed specifically for ultra-tight tolerance applications
  • Low equivalent circulating density (ECD) signature to lower surge effect during run-in-hole (RIH)
  • Allows for rotation when fully compressed
  • Fewer bows for more efficient RIH
  • Will meet or exceed host casing burst and collapse specifications
  • Interlocked band design gives the strength of a single piece centralizer

Targeted applications

  • Deepwater
  • Ultra-narrow, close tolerance
  • Alternative to standard subs that will have higher initial insertion forces due to bow design

"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.”
