MULTIBACK

Configured for specific applications or requirements

The MULTIBACK tool is run in the well as a conventional wellbore preparation tool on the workstring. The lanterns for the scraper and brush unit are flexible, non-rotating, and provide the force to contact and clean 360° of the casing’s internal diameter. Its self-centralizing design ensures equal cleaning force at all angles of inclination. The magnet section comprises a mandrel with fins that allow for large flow channels between them. The magnets are installed on the inside faces of the fins using a method for retaining the individual magnets so that the debris is collected in the high volume channels. The magnet section is integral in the tool while the scraper and brush sections are interchangeable (see below).
