Wire Scratcher

COS's Aluminium Spiral Vane Solid Rigid Centralizers are developed in response to the need for better cementing in high deviated and horizontal well. These are designed to provide optimum flow and its fins or blades overlap the entire 360-degree open hole circumference. Therefore its reduced flow area between the spiral provides and creates vortex motion to increase fluid velocity with direction. Even without rotation, the relived angle fins/ blades induce turbulent flow for improved cutting and filter cake removal.

The angle of the uniquely designed spiral fin produced maximum fluid swirl, thus maximum removal of debris around the casing in any type of hole. These Centralizers withstand high well bore temperature while providing maximum horizontal standoff.

These are available in 2 7/8" to 30 " sizes. Any special sizes or combination can be made available on request.

Cable Wall Cleaner

The reciprocating cable wall is a slip-on cleaner with an internal locking device . The overlapping high-alloy cable is interlaced with a full 360 degrees around the band.

The bold holds the wipers in place and eliminates the need for stop collars. The Cable Wall Cleaner comes with a solid band styles and with a hinged design to use it on casing and tubing. This also takes away excess wall cake to improve the cement formation bonding by producing a wiping action during running and reciprocation.
