The Evolution Model ERB Pulling Tool is designed to engage and retrieve downhole tools with an external fishing neck.  Upward jarring is utilized to release the tool to be pulled.

Operation

The tool is operated by locating the lower end over the external fish neck of the tool to be pulled. The pulling tool dogs latch onto the fishing neck. Cam surfaces on the dogs force the lower end of the dogs to be pressed inward, thereby ensuring  a strong latch.

The ERB pulling tool (R body with a B core) pulls Otis® B, C, and W lock mandrel assemblies and mandrel assemblies with full relative motion.

Should the pulling tool not be able to retrieve the downhole tool, it can be released from the fishing neck so it may be brought out of the well. The shear pin can be sheared with repeated severe jarring. Once sheared, the cylinder spring forces the core to move up. This releases the pulling tool dogs.

Once the lips of the pulling tool dogs release, the ERB can be removed from the hole and the shear pin replaced.
