This tool is ideal for the removal of dirt which may be left over the inside walls of casing, suchas solid cement, hard wax, various salt crystals or deposits, perforation burrs, iron oxideresidues resulted from rusting, so as to make all down hole tools pass through unblocked.Especially when a small circular clearance is available between the down hole tools andcasing inside diameter, the complete scrapping becomes more necessary before furtherworking. At present in the large petroleum well scrapping in the internal wall of casing by useof casing scraper is a necessary step.
