Abstract
A jarring tool includes a main body having a central bore extending therein, an upper connection at a proximal end of the main body for attaching the jarring tool to wireline or slickline, a lower portion at a distal end of main body, and a reciprocating hammer fixed at a first position within the central bore of the main body. The jarring tool further includes a central aperture extending along a length of the reciprocating hammer, an electrical connector extending from the upper connection and through the central aperture of the reciprocating hammer to at least the lower portion of the main body, and a release mechanism on the main body for releasing the reciprocating hammer from the first position and allowing reciprocating movement of the reciprocating hammer along the central bore. The electrical connector is configured to break when the reciprocating hammer is released from the first position.
