-KINGWELL SUPER Unique Shape-Razor™ Scraper
KINGWELL SUPER Unique Shape-Razor™ Series is a heavy duty wellbore clean-up scraper suitable for all downhole conditions and with robust, high performance features.
Run separately or as part of a comprehensive wellbore clean-up, the KINGWELL SUPER Unique Shape-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.
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
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
The KINGWELL SUPER Unique Shape-Razor™ scraper is typically the first tool run in a BHA ahead of a brush, magnet or filter tool as it is the most aggressive and most robust tool of this type.
As the Scraper Cage enters the casing, the leading centralizer guides and centralizes the tool. The leading edge of the Scraper Cage blade compresses as it is squeezed into the casing, acting as a self-sprung solid state component.
While running in the hole, the self-cleaning teeth scrape the casing wall removing cement and other hard debris. Internal bearings ensure that the Scraper Cage is pulled into the well, rather than pushed, which prevents collapse of the Scraper Cage.
Once at the packer setting depth, the CHIMERA SUPER Shape-Razor™ is typically reciprocated three or more times across the critical depth while rotating and reciprocating the string.
The bronze alloy bearings have both axial and radial elements to allow extended rotation of the string without damage or wear to the tool or the casing.
The optional integral string mill can be sized to casing drift and is particularly useful when used in a cement milling BHA, as the string mill will help to break up cement and remove any
residual debris left by the mill.

The MATECLEAN  wellbore preparation tool builds on field proven scraper, brush, and magnet technology to supply a single fit-for-purpose tool that can be utilized in standard wellbore displacement and workover applications or sold as part of the completion assembly to provide additional cleaning during installation.
The design of the MATECLEAN incorporates existing technologies from other Baker Hughes wellbore cleanup products for increased reliability and synergy. The tool is designed with large ID’s to accommodate high flow rates. The integrated tool incorporates three independent technologies into one system. The scraper section is used to remove mud or cement sheath, perforation burs, rust, scale, paraffin or similar substances from the casing inside diameter (ID). The brush section assists the scraper in removing debris from the casing ID and helps to agitate fluid during displacement applications for improved effectiveness. The magnet section collects ferrous debris from the wellbore and retrieves it to surface.
The MATECLEAN wellbore preparation tool can be used in a variety of applications, whether it be temporary wellbore cleanup service or permanent installation with downhole completion and intervention systems. In standard wellbore cleanup and displacement applications, the MATECLEAN offers a cost effective, integrated solution for cleaning the wellbore. Additionally, the tool may be run ahead of bridge plugs, whipstocks, lower completion systems, or other systems that will be temporarily or permanently installed in the wellbore. The MATECLEAN assists in cleaning debris ahead of these other products and helps to prepare the setting area, improving the system reliability. The tool’s simplistic, yet robust design makes it a cost-effective solution for a variety wellbore cleanup applications.

 A clean well is essential prior to running expensive and sensitive completion strings or other debris sensitive equipment. Therefore removal, collection of debris and verification of debris removal are extremely important in a wellbore. These operations can be optimized by the Sharp-Razor™ Wellbore Cleaning equipment.

Sharp-Razor™ Casing Scraper is a mechanical tool for clean and polishes the casing or liner ID to remove mud solids, cement sheath, scale and perforation burrs in any wellbore.

The Sharp-Razor™ Casing Scraper can be integrated as a part of a complete
wellbore cleaning tool string used during displacement process prior to
running completion. It can be rotated and reciprocated without fear of
damage to casing or tool due to the rugged design and the fact that
it doesn’t contain external bolts that could work loose under extreme

A Sharp-Razor™ Casing Scraper tool consists of a one-piece Body, non-rotating
Stabiliser and Scraper assembly. The main mandrel rotates through the stabiliser and Scraper assembly to avoid wear or damage to the casing during drill string rotation. The Scraper assembly is self-centralising inside the casing or liner to ensure equal cleaning at all well conditions. It’s also rough, flexible and has the force needed remove and clean 360 degrees without rotation.

The tool is suitable for HPHT wells and can withstand chemical or acid attack.
