Abstract
A wellbore system includes an adapter configured to couple to a downhole component. The wellbore system also includes a retrieval tubular, having a bore extending therethrough. The wellbore system further includes a piston assembly coupled to the retrieval tubular, wherein the bore is in fluid communication with a cavity of the piston assembly. The wellbore system includes a stem configured to couple to a casing section, the casing section being supported by a hanger. The wellbore system also includes a sleeve forming at least a portion of the piston assembly, the sleeve configured to couple to the adapter such that, responsive to a force applied by the piston at the casing section, the sleeve applies an upward force to the adapter.
