A perforating apparatus (100) includes a plurality of shaped charges (102)
each having an initiation end and a discharge end. A detonating cord
(116) is operably coupled to the initiation ends of the shaped charges
(102). A carrier (106) contains the shaped charges (102). The carrier
(106) includes at least one discharge location corresponding to the
discharge ends of the shaped charges (102) when the perforating apparatus
(100) is in its operable position. The discharge location has first and
second material layers (122, 124) wherein the second material layer (124)
exhibits resilient recovery such that an opening created by a jet formed
from detonating one of the shaped charges (102) in the second material
layer (124) is smaller than an opening created by the jet in the first
material layer (122), thereby retaining debris in the perforating
apparatus (100) with the second material layer (124).
