  • Patent number: 7828051
    Abstract: An improved perforating gun having a tubular housing, a tubular carrier and a charge carried by the tubular carrier. The tubular carrier comprises an inside diameter, an outside diameter and an opening disposed between the inside diameter and the outside diameter. The charge comprises a forward end positioned in the opening between the inside diameter and the outside diameter. The tubular carrier increases a collapsible-pressure rating for the housing and positions the charge closer to the formation.

  • Patent number: 7621342
    Abstract: 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).

  • Patent number: 7360599
    Abstract: A perforating apparatus (100) includes a plurality of shaped charges (102) each having a case, an initiation end and a discharge end. A detonating cord (116) is operably associated with the initiation ends of the shaped charges (102). An energy absorbing charge holder (104) has a detonating cord receiving area to receive the detonating cord therein (116). The energy absorbing charge holder (104) also has a plurality of charge receiving locations that closely receive the shaped charges (102) therein such that upon detonation of the shaped charges (102), energy is transferred from the cases of the shaped charges (102) to the energy absorbing charge holder (104), thereby reducing fragmentation of the cases.
