SUPER Unique Sharp-Razor™ Scraper
Introduction
WELLBORE SUPER Unique Sharp-Razor™ Series is a heavy duty wellbore clean-up scraper suitable for all downhole conditions and with robust, high performance features.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 dril pipe connections

Giant-Mag™
Introduction
WELLBORE Giant-Mag™ is a wellbore clean-up magnet suitable for all downhole conditions and with robust, high performance features, is designed to recover large volumes of ferrous debris to ensure the integrity of the wellbore cleanup. The magnet features a large magnetic surface area along with discrete flow channels to combine higher magnet strength with greater volume to optimize recovery.
Features
Compact design- Single piece mandrel.
High strength rare earth magnets.
Fixed stabilizer sleeve to provide stand off when POOH.
Optional dedicated flow channel to prevent flow path restrictions when packed full of debris
Advantages
Mainly used in perforated casing or liner to remove perforation burrs and to ensure the safe passage of completion equipment.
Removable magnets for body inspection .
Recovered material is easily removed on location.
High temperature rating on magnets up to 350%F (177°C) .
Debris channels allow for larger volume of ferrous material to accumulate.
Applications
Run separately or as part of a comprehensive wellbore clean-up, which designed to capture ferrous metal debris in the wellbore. or as an integral part of the drillstring during wellbore preparation operations.
Grand-Mix™ (GM) Combination casing cleaning tools
Introduction
WELLBORE Grand-Mix™ (GM) consists of the latest generation scraper, brush and high capacity magnet, combined them into a simplified and rugged tool, which has an integral magnet section to capture ferrous debris, scrapers to dislodge difficult to-remove debris, and brushes to disturb the sheath and any other fluid build-up on the inner wall of the casing or liner. The tool can be run in the inner production riser, casing, and liner to remove a combination of scale, rust, mud film, drilling debris, ferrous debris, and pipe dope.
Features
One tool carries scrapers, brushes, or magnets on the same mandrel.
Large flow area between magnets to capture large debris
Brush component can be readily redressed at remote locations
Available with any tubing connection to run directly on the completion tubing.
Applications
The Grand-Mix™ can be configured for any Casing and Tubing combination with matching metallurgy and connections
