SUPER Unique Sharp-Razor™ Scraper

Introduction

SUPER Unique Sharp-Razor™ Casing Scraper is a heavy duty wellbore clean-up scraper suitable for all downhole conditions and with robust, high performance features.
Running separately or as part of a comprehensive wellbore clean-up, the SUPER Unique Sharp-Razor™ is designed to effectively remove cement and other debris from the casing wall, through reciprocation.
The scraper cage flexes like a spring, to conform to the casing internal surface, to mechanically remove hard debris from the casing.
The alloy bronze bearings feature both axial and radial elements to allow extended rotation in harsh environments preventing tool and casing wear. The Heavy Duty version includes an integral string mill. The Standard Duty version comes with a plain external diameter.

Features

Solid state scraper cage and centralizers, manufactured from a single billet without the need for springs, bolts or pads.
Non-rotating design with high performance alloy bronze bearings, compatible with high temperature and chemical applications.
Optional integral string mill with crushed carbide blades to remove cement.
Available with all API and premium drill pipe connections.

Benefits

A properly executed wellbore clean-up mitigates risk during completion operations and the productivity of the well.
Prevent debris related premature packer setting while RIH
Assists in chemical cleans action
Prepare casing wall to ensure packer element sets and mitigate premature elastomer failure
