RAZOR BACK

Casing cleaning tool

Our standard RAZOR BACK casing cleaning tool represents a step-change improvement over the metal-bladed casing scrapers used previously. This new-generation design controls even the most complex wellbore cleanup operations.

The RAZOR BACK tool incorporates critical and evolutionary features not found on any other metal-bladed casing scraper. We designed this technology as an effective, robust, and safe alternative to other devices used in wellbore cleanup and casing scraping operations.

The RAZOR BACK tool is run as an integral part of the drillstring to scrape the casing as the pipe is run in hole. It can be run as part of most drilling, milling, and polishing assemblies as a stand-alone device. More often, it is run with circulating tools and the WELL PATROLLER validation tool as part of a total cleanup system. It can be rotated and reciprocated without damaging the casing or tool itself.
