  • Shearing tool and methods of use
    Patent number: 8376055
    Abstract: A shearing tool for shearing, trimming, or reducing objects being pulled through a drill string and methods for retrieving retrievable tools with fins from the drill string, where the retrievable tools must pass through restrictions in the drill string having interior diameters less than the outer diameters of the fins. The fins, affixed to the retrievable tools, provide stability to the tools, while within the drill string, and can be made of rubber, plastic, other shearable materials, or combinations thereof. The apparatuses and methods include inserting a shearing tool with a flange into a box end of a section of drill string, where the flange keeps the shearing tool in place. The shearing tool further comprising a cutting surface for cutting materials pulled through the shearing tool.
