Abstract

A shaped charge assembly for selectively expanding a wall of a tubular includes a housing comprising an outer surface feeing away from the housing and an opposing inner surface facing an interior of the housing. First and second explosive units each includes a predetermined amount of explosive sufficient to expand, without puncturing, at least a portion of the wall of the tubular to form a protrusion extending outward into an annulus adjacent the wail of the tubular.
