Downhole jarring tool with electrical pass through

A system for impacting a downhole tool or a stuck component in a wellbore, comprising:

• a wireline tool string or a slickline tool string configured to be inserted into the wellbore;
• a jarring tool attached to a portion of the wireline tool string or the slickline tool string, wherein the jarring tool comprises:
• a main body including a central bore extending therein;
• an upper connection at a proximal end of the main body for attaching the jarring tool to the wireline tool string or the slickline tool string;
• a lower portion at a distal end of the main body;
• a reciprocating hammer fixed at a first position within the central bore of the main body and including 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;
• 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 of the main body;
• and
• a controller for reciprocatingly moving the reciprocating hammer along the central bore of the main body, wherein the electrical connector is configured to break when the reciprocating hammer is released from the first position, and wherein the reciprocating hammer is configured to impact the downhole tool or the stuck component in the wellbore via the reciprocating movement.

A method for impacting a downhole tool or a stuck component in a wellbore, the method comprising:

• attaching a jarring tool to a portion of a wireline tool string or a slickline tool string, the jarring tool comprising:
• a main body including a central bore extending therein;
• an upper connection at a proximal end of the main body for attaching the jarring tool to the portion of the wireline tool string or the slickline tool string;
• a lower portion at a distal end of the main body;
• a reciprocating hammer fixed at a first position within the central bore of the main body and including 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 of the main body;
• applying an over-pull tension to the jarring tool to release the release mechanism, move the reciprocating hammer from the first position, and break the electrical connector;
• and
• reciprocatingly moving the reciprocating hammer along the central bore of the main body to impact the downhole tool or the stuck component in the wellbore.
