FUNCTIONAL PURPOSE

The Casing Scraper is used for removing the stuck mud cement embedded bullets, perforation burrs, rust, mill scale, paraffin and similar unwanted material from the inside wall of the Casing.

OPERATIONAL HIGHLIGHTS

For removal of the Cement Sheath the Scraper should be installed between the Drill Bit and the Drill Collar so that both the drilling out and the sheath removal can be accomplished at the same time. It is a good practice to maintain circulation while these operations are being conducted. For removal of  perforation burrs and bullets, the scraper is installed pin up on the first joint of the drill pipe with an old three cone rock bit installed in the box end of the scraper.
