Can Centek S2 single piece bow spring centralizer travel through a restriction?

Our S2 centralizers are developed to be utilized in gauge applications. We do not recommend their use in a continuous restriction or under-ream application without simulations. We would advise customers to run our TUR or UROS centralizers which are specifically designed to pass through tight restrictions and engineered for under-reamed applications.

S2 HIGH PERFORMANCE SINGLE PIECE

The revolutionary S2 bow spring centralizer is a high-performance, single-piece solution specifically designed for challenging wellbores.

Its engineered combination of strength and flexibility enhances run-in-hole (RIH) efficiency, reducing time and costs for operators aiming to reach total depth.

The S2's single-piece construction eliminates weak points, making it highly durable in demanding casing running environments. It is particularly suited for severe well geometries, high build rates, extended reach, and J-type and S-type wells, as well as high-temperature, high-pressure (HTHP) applications.

UROS PATENTED OFFSET BOW DESIGN

The UROS centralizer features a patented offset bow design that significantly reduces starting and running forces in wells with under-reamed sections.

It is specifically engineered to address challenges in navigating through previously set casings and expanding into open-hole sections. With its ultra-high-strength, single-piece bow spring design, the UROS centralizer offers enhanced durability and flexibility, allowing it to handle both axial and radial loads effectively without any weak points.

TUR FLEXIBLE WITH LOW START AND RUNNING FORCES

The Centek TUR bow spring centralizer is engineered for use in close tolerance, under-reamed applications commonly found in some of the world’s most challenging offshore fields.

The flexible TUR centralizer excels in providing effective cementation through restrictions. Its large flow-by area enhances fluid dynamics, ensuring improved circulation and displacement efficiency, which are crucial for achieving optimal cementing results in difficult wellbore environments.
