Patent abstract
An overshot tool is provided for interconnecting and sealing between a lower tubular (C) in a well and an upper tubular (30). A tubular expander sleeve (36) and an overshot sleeve (26) are supported in a well on an upper tubular. The tool housing (60) encloses a plurality of axially stacked pistons (58, 68, 74), 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.
