The ballistic housing includes a first housing portion including a chamber (), and a second housing portion having a noncompressible core. The outer seal housing is circumferentially disposed around the noncompressible core (). According to an aspect, the initiator () is positioned within the chamber and a detonation extender () is in ballistic communication with the initiator and is circumferentially disposed around the noncompressible core. The detonation extender is configured to, upon detonation, expand the outer seal housing () from an unexpanded form to an expanded form to secure the outer seal housing within the wellbore casing.
