Abstract
An electromagnetic jarring tool and related systems and methods provide for the use of an electromagnetic system to generate jarring forces within a wellbore. The electromagnetic jarring tool includes a chamber having a first end and a second end, a magnetic hammer disposed within the chamber, and an electromagnet operable to generate an electromagnetic field across at least a portion of the chamber. The magnetic hammer is operable to move toward the second end of the chamber in response to the electromagnetic field to deliver an impact. One or more electromagnets may be included to enhance operation of the tool, and the tool may be actuated by a surface controller that selectively delivers electrical power or a control signal to the tool to specify a mode of operation of the electromagnetic jarring tool.
