US 2022/0025728 A1 · MAGNETIC FISHING TOOL AND USE THEREOF IN FISHING OPERATIONS

Abstract

A method of removing a target fish from a wellbore includes preparing a fishing assembly having a magnetized pipe coupled to an end of a work string. The fishing assembly is run into the wellbore, and the magnetized pipe is positioned at an effective position in which a threaded end of the target fish is aligned with a threaded end of the magnetized pipe by magnetic attraction between the magnetized pipe and the target fish. A threaded connection is made up between the threaded end of the target fish and the threaded end of the magnetized pipe. The fishing assembly with the attached target fish is then retrieved from the wellbore to a surface location.
