Patent number: 7621342Abstract: 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).Type: GrantFiled: August 29, 2008Date of Patent: November 24, 2009Assignee: Halliburton Energy Services, Inc.Inventor: Jerry L.
