UROS Offset Bow Spring Centralizer

• Under-reamed Bow Spring Centralizers
• UROS Offset Bow Spring Centralizer
• TUR Bow Spring Centralizer

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.

This robust centralizer provides over a 50% reduction in starting and running forces compared to traditional under-ream products, ensuring smoother run-in-hole (RIH) performance even in tight annular restrictions. The UROS centralizer is designed to return to gauge in open-hole sections, enhancing standoff and zonal isolation. Ideal for demanding applications like under-reamed well sections, tight annular spaces, offshore and deepwater projects, and complex well paths such as horizontal/ERD and S-Type/J-Type wells, the UROS centralizer meets the unique engineering challenges posed by compressed bows in under-reamed sections.

Under-reamed sections

Under reamed well sections create a number of engineering issues which affect the run-in-hole (RIH) performance due to the bows being ‘compressed’ while passing through smaller ID of the previous set casing.

The UROS is engineered to significantly reduce starting and running forces associated with under reamed well sections. Returning to gauge enhances RIH, stand-off and successful zonal isolation.

Performance ratings

Centralization and the ease of running casing is often a balance between strength and flexibility which combine to support, what we call, 'runability'. To help with product selection we've added a rating to all our products for flexibility, runability and inherent strength.

Sizing

UROS centralizers are available in sizes from 7 to 17"
