What type of fishing tool is referred to as a Tapered Tap?

A Tapered Tap is specifically designed for the purpose of retrieving an open-ended fish, which refers to a piece of equipment or debris that has become lodged or stuck in a well. This tool utilizes a tapered design to effectively grab hold of the obstructive fish by cutting threads into it. The threads allow for a secure grip, enabling the operator to pull out the obstructions safely and effectively from the borehole.

This functionality is critical in the drilling process, where equipment can sometimes become lodged, creating delays or complications in drilling operations. Therefore, the tapering feature provides an efficient means to retrieve those items without causing additional damage to the well structure or other tools.

Other options, while mentioning different tools related to fishing in the context of well drilling and maintenance, do not describe the unique purpose of the Tapered Tap, which is focused on threading and retrieval capabilities.
