Audited Supplier This new-generation improvement in metal-bladed scraper design brings even the most complex wellbore cleanups under control. The RAZOR BACK (RB) tool has critically important features not found on any other metal-bladed casing scraper that render it more effective, robust, and safer to use in wellbore cleanup and scraping operations.
Advantages: The lantern is self-centralizing inside the tubular to ensure equal cleaning force at all angles of well inclination. The mandrel rotates through the stabilizer sleeves and lantern to avoid wear or damage to the casing during pipe rotation. The tool is HTHP-compatible and is not vulnerable to chemical or acid attacks.
The HEAVY-DUTY RAZOR BACK tool is run with a maximum running-in-hole and pulling-out-of-hole speed of 150 ft/min [46 m/min] and should be positioned at least 30 ft [9 m] above the drill bit or mill. The string should be picked up off the bottom and circulated regularly to clear any accumulation of debris.
Where possible, the bit or mill OD should be greater than the stabilizer sleeve OD of the tool. If this is not possible, it is recommended that a full-gauge mill be run below the first HEAVY-DUTY RAZOR BACK tool in the bottom-hole assembly.
