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.
