Abstract
A sealing tool, system and method for sealing a wellbore achieves increased expansion with the use of a seal seat extender. In one example, a seal seat (e.g., a ball seat) defines an axial flow bore in fluid communication with the wellbore to be sealed, a sealing profile for receiving a loose sealing element (e.g., a ball or dart) to close the axial flow bore, and a tapered outer profile. The seal seat extender is initially disposed against the seal seat and is expandable against the seal seat in response to an axial setting force, such as by sliding up the tapered outer profile of the seal seat and/or buckling outwardly, in response to a setting force. A compliant annular packing element disposed against the seal seat extender is deformable outwardly into sealing engagement with the wellbore in response to the axial setting force.
