  • Method and apparatus for catching and retrieving objects in a well
    Patent number: 9903183
    Abstract: A magnet assembly having selectively removable magnet members can be attached to, or placed in the vicinity of, a conventional bell nipple or riser on a drilling rig to generate a magnetic field within a wellbore. The magnetic field catches falling metal objects and prevents such objects from passing beyond the magnet assembly and entering subterranean portions of a wellbore. Hatch doors are provided for easy access to inner portions of the magnet assembly.
    Type: Grant

  • Method and apparatus for catching and retrieving objects in a riser assembly
    Patent number: 9458702
    Abstract: A riser magnet assembly having selectively removable magnet members can be incorporated within a riser assembly of a drilling rig to generate a magnetic field within a central bore of the riser assembly. The magnetic field catches falling metal objects and prevents such objects from passing beyond the magnet assembly and entering subsea equipment or subterranean portions of a wellbore without sacrificing fluid pressure integrity of the riser assembly. At least one stripper door is provided for easy access to inner portions of the magnet assembly.

  • Method and Apparatus for Catching and Retrieving Objects in a Well
    Publication number: 20130020096
    Abstract: A magnet assembly can be attached to, or placed in the vicinity of, a conventional bell nipple to generate a magnetic field within the central bore of the bell nipple. The magnetic field catches falling metal objects and prevents such objects from passing beyond the bell nipple and entering the subterranean portions of a wellbore. An optional diverter assembly slows the velocity of falling metal objects before reaching the magnet assembly, while also wiping the outer surface of pipe or other items lowered into a wellbore.
