The casing centralizer is designed to center casing strings and liners during descent in vertical, directional, and horizontal wells

Improving the quality of cementing operations in wells with a high angle of inclination and in horizontal wells

Rigid Casing Centralizers have lower resistance compared to steel centralizers

A 30° inclination of the end of the Casing Centralizers' blades creates direction and helps guide the casing string to the bottom of the well

Reduces frictional forces under torsional and axial loads, improving operational efficiency through better power transmission to the tool

The option to reinforce the AVRORA-290 Casing Centralizers with steel rings on both ends

Exhibits zero starting resistance

SPRING CENTRALIZERS AVRORA FOR WELLS

The Avrora spring centralizer for casing pipes is an excellent solution for centering casing strings in wells of any type. Our well centralizers, with their semi-rigid design and convenient fastening with locking rings, ensure an even gap between the casing and the well walls, improving the cementing process and preventing potential risks.

PRECISION IN TESTING

Avrora LLC has its own high-precision technological test stands to determine the Axial Starting Force and the Centralizer Pushing Force, as well as to measure the Magnitude of Radial Centering Force. Avrora centralizers, designed for well equipment, guarantee uniform centering, optimal lowering, and high-quality cementing.

ENGINEERING SUPPORT

We accompany the supply of centralizers with the development of specialized programs, providing recommendations on the optimal number and positioning of the centralizers. To ensure direct monitoring of program execution, we are ready to send a service engineer to supervise the running of the casing.

SOFTWARE

Our licensed software suite accurately models the casing running and calculates the placement of centralizers, taking into account factors such as cementing quality, torque, drilling conditions, and wellbore deviation to minimize risks during the casing running.
