Abstract
A shaped charge assembly for use in a perforating gun that comprises a shaped charge holder, two or more shaped charges, slots formed to receive the shaped charges, and an impedance barrier disposed between adjacent shaped charges. The impedance barrier can comprise a gap formed in the shaped charge holder, where the impedance barrier runs across the shaped charge holder. The impedance barrier can be a void formed on the surface of the shaped charge holder, or can include shock attenuating material therein, such as wood, cork, cotton, polymeric materials, and combinations thereof, to name a few.
