Abstract
A well abandonment tool comprising an elongate housing extending between top and bottom ends locatable within a wellbore having a longitudinal pumping cylindrical bore with a pumping piston therein. The apparatus further comprises a wellbore seal located around the housing operable to engage upon the wellbore and to be expanded into contact therewith upon an upward motion of the housing so as to seal an annulus between the housing and the wellbore and a bridge plug engagement connector adapted to secure a bridge plug thereto at a position below the bottom end of the housing. The pumping piston is suspended from a wireline wherein longitudinal movement of the pumping piston discharges a fluid into a bridge plug activation chamber having a movable cylinder adapted to draw the bridge plug engagement connector against the bottom end of the housing so as to expand the bridge plug into engagement with the wellbore.
