Abstract
An overshot tool is provided for interconnecting and sealing between a lower tubular (C) in a well and an upper tubular (). A tubular expander sleeve () and an overshot sleeve () are supported in a well on an upper tubular. The tool housing () encloses a plurality of axially stacked pistons (), which generate an axial force to move the expander sleeve downward and radially expand a portion of a lower tubular to seal between an outer diameter of the lower tubular and an inner diameter of the overshot sleeve.
