Abstract
An instrument for the mechanical removal of corrosive buildup, deposits or scale from within a wellbore. A tubing-conveyed scraping blade and/or other abrading devices () has a collapsible maximum outer diameter by using a multi-bar mechanism () to ensure physical contact with corrosive buildup, deposits or scale on surfaces of a surrounding wellbore, oil and gas tubular, or drilling/production marine riser (and, in particular, inner surfaces thereof). The multi-bar mechanism allows for a wide range of motion irrespective of the direction of loading and variable maximum outer diameter to clean corrosive buildup, deposits or scale from tubular goods with unknown configurations and/or dimensions.
