Casing Scraper

The GOTCO Casing Scaper is designed to remove scale, mud cake, cement sheath, embedded bullets, and other foreign material from inside of the casing wall.

Maintaining a clean casing I.D. is vital to the efficient operation of down-hole tools used in drilling the well. The resulting smooth surface properly prepares the casing for subsequent down-hole operation such as packer setting and squeeze tools.

Construction

Manufactured from alloy steel and heat treated to provide strengh and durability, each scraper must pass rigid non-destructive testing to ensure the highest quality product.

Each tool has six blades specially aligned on the body to provide the maximum cutting surface area for vertical and rotational scraping. The blades are designed to give optimum shearing action with the least amount of restriction to returning well fluid. The splined body provides absolute safety and security by locking each blade onto an integral part of the scaper.

This unique body design aslo allows for ease of maintenance and dressing of the tool. All casing scrapers can easily set for positive or spring loaded scaping action. Even when set positive to drift, the spring loaded design will effectively scrape multi-weighted casing within the well. All blades are cast steel and heat treated to provide long lasting service life.

Assembly

Assembly of the casing scraper is quick, simple and can easily be done in the field.
  1. Secure the tool body.

  2. Insert springs into the blade body drive.

  3. Set blade over body splines at center of tool, compress blade and slide into splines.

  4. Install remaining blades in the same manner.

  5. Offset the upper blade set from lower set by one spline.

  6. Secure blades to body with split collar ring.
