  • Downhole fishing tool for retrieving metallic debris from a borehole
    Patent number: 6629562
    Abstract: The invention is a system for retrieving loose metallic debris, such as stray radioactive marker bullets, from a borehole in a subterranean formation. The system can be used to retrieve stray radioactive marker bullets during placement of the radioactive marker bullets in the subterranean formation. The system utilizes a downhole fishing tool having at least one recessed magnetic surface for attracting and holding stray radioactive marker bullets. The recessed magnetic surface allows the fishing tool to be removed from the borehole without scraping off retrieved marker bullets that are held against the magnetic surface.
