    Abstract: A method includes conveying a sacrificial tool into a wellbore on a conveyance, the wellbore penetrating one or more subterranean formations and the sacrificial tool including an overshot fishing tool, a tubing operatively coupled to and extending from the overshot fishing tool, and a liner hanger arranged at an upper end of the tubing. An uphole end of a downhole tool is received within with the overshot fishing tool, the downhole tool being stuck in the wellbore adjacent the one or more subterranean formations. The uphole end of the downhole tool is sealingly engaged, and a cement is subsequently circulated through the sacrificial tool and the downhole tool and discharged into an annulus defined between the downhole tool and an inner wall of the wellbore.
