摘要
A shaped charge assembly for selectively expanding a wall of a tubular includes first and second explosive units that are each symmetrical about an axis of revolution. Each explosive unit includes an explosive material that is liner-less. The first and second explosive units comprise a predetermined amount of explosive sufficient to expand, without puncturing, at least a portion of the wall of the tubular into a protrusion extending outward into an annulus adjacent the wall of the tubular.
