Product Description
Casing scraper is one useful tool designed to remove scale, mud cake, cement sheath, embedded bullets, and
other foreign materials from inside of the casing wall in work over operation. Jereh offers various casing
scrapers and also can supply highly customized casing scrapers as per customer's requirements.
This tool is ideal for the removal of dirt which may be left over the inside walls of casing, such as solid cement, hard wax, various salt crystals or deposits, perforation burrs, iron oxide residues resulted from rusting, so as to make all downhole tools pass through unblocked. Especially, when a small circular clearance is available between the downhole tools and casing inside diameter, the complete scrapping becomes more necessary before further working. At present in the large petroleum well, scrapping in the internal wall of casing by use of casing scraper is a necessary step.
