Abstract: A detonator housing facilitates assembly of detonator components of a perforating gun. In an example, the detonator housing comprises a housing body configured for coupling to a charge tube of a perforating gun. A detonator receptacle is formed on the housing body for receiving a detonator. A detonating cord receptacle is formed on the housing body adjacent the detonator receptacle for receiving an end portion of a detonating cord in an overlapping relationship with the detonator. A detonating cord stop is formed on the detonating cord receptacle to limit an insertion depth of the detonating cord within the detonating cord receptacle.

Abstract: A perforating gun connection is disclosed whereby a signal may be carried from surface, down through a wireline or other conveyance, and across the connection from the pin on one perforating gun to an electrical contact structure on the next perforating gun in the string. In an example, the connection includes a connector body with an electrical pin positioned for contact with an electrical contact structure on the next perforating gun. The electrical contact structure has a contact tab aligned for engagement by the pin when connected with the connector body. The electrical contact structure may be unitarily formed to include a number of features to facilitate connection between perforating guns.

Abstract: An impact sleeve is used for mitigating damage in a perforating gun resulting from shaped charge detonation. In one example, a perforating gun includes a gun carrier, with a charge holder and the impact sleeve inside the gun carrier. The charge holder holds a plurality of shaped charges capable of being detonated with sufficient explosive energy to generate high-velocity fragments inside the gun carrier. The impact sleeve comprises an energy-absorbing material and optional raised features for absorbing at least some energy of the high-velocity fragments. The materials, raised features, positioning, and geometry of the impact sleeve and raised features may be tuned to optimize energy absorption.

Abstract: The disclosed embodiments include bulkheads for perforating guns and perforating gun assemblies. A bulkhead includes a threadless exterior surface that spans a length of a threaded connection of adjacent first and second perforating guns. The bulkhead also includes a first exterior groove having a first sealing element partially disposed in the first exterior groove. The bulkhead further includes a second exterior groove having a second sealing element partially disposed in the second exterior groove, where the first sealing element and the second sealing element are positioned around the threaded connection.

Abstract: A method and systems for perforating a formation surrounding a borehole that include placing a perforating gun assembly into the borehole, the perforating gun assembly including a gun body comprising a connector and a shaped charge within the gun body. The shaped charges are detonated, thereby producing a shock wave in the gun body. The shock wave propagating through the gun body is attenuated using a shock attenuation feature in the gun body to decrease a stress from the shock wave communicated to the connector.
