Abstract
A combination jarring tool and disconnect device is disclosed in which the jarring events may be followed by separate disconnect event, or in which the jarring events may coincide with disconnect events. The tool generally comprises a housing and a sleeve in concentric arrangement and a disconnect interface. A plurality of axial and rotational locks is used to prevent premature energization of the jarring and disconnect events.
