Chemical Cutters for Stuck Tubing or Drillpipe
The chemical cutter is a tool designed to cut and allow retrieval of stuck tubing or drillpipe in a well. The primary advantages of this tool over explosive methods are its ability to sever tubing without causing the following undesirable problems:
- damaging the well casing or adjacent tubing
- enlarging or leaving a burr on the OD of the cut.
In addition to cutting, the tool can be adapted to perforate one to four holes in the same plane to establish circulation or equalise pressure . . .
