Casing scraper

The Casing Scraper is used to clean out the dirts which may be left over internal wall of casing, such as cement scale, sandy soil, embedded bullets, score mark, hard wax, various salt crystals or deposits, perforation burrs and iron oxide resulted from rusting, so as to keep the wall of casing clean and to lay down all downhole tools freely. Likewise, packers and other similar tools must have a clean junction surface.
