Casing Roller |
| The GOTCO Casing Roller is a repair tool designed to restore buckled, collapsed, and dented casing to its original diameter. |
Construction |
| Manufactured from specially selected alloys, designed specifically to resist wear, the casing roller can be used to restore any size and weight of casing. The casing roller consists of a mandrel with a box connection up and three heavy duty rollers. the I.D. of each roller is precision ground to assure proper rotation on the mandrel. Securing the rollers to the mandrel is a nose cone which is retained by large ball bearings. A through bore provides circulation capabilities. Tools may be run effectively at relatively slow rotary speeds and are avialable with left hand connections if desired. |
Operation |
| The casing roller should be made up to the bottom of the drill string. Lower the pipe and rotate slowly until the damaged section is reached. Start circulation, increase rotation speed and continue to lower slowly. The tapered nose cone will enter and guide the tool, allowing it to open the collapsed portion to its original size. Use of too little pressure will wear the tool without restoring the casing. Be sure adequate downward pressure is maintained. Add drill collars if the string weight is insufficient to assure continued downward progress. |
