Abstract: A method and apparatus for inserting a detonator into a door on an end fitting and closing the door into a recess of the end fitting, enabling a quick wireless install of a detonator and resulting in a side-by-side arrangement between the detonator and the detonating cord.

Abstract: A method and apparatus for containing one or more shaped charges in a single plane, arrayed about the center axis of a gun body, and detonated from a single initiator in a shaped charge cluster assembly, having one or more detonator circuits located within a recess within the shaped charge cluster assembly electrically coupled to the single initiator located at the center of the arrayed shaped charges.

Abstract: A method and apparatus for controlling a perforating tool string using a perforating unit with a control board and shooting power supply.

Abstract: A method and apparatus for detecting the orientation of each perforating gun in a wellbore and using that information in arming and firing each perforating gun in a perforating gun string.

Abstract: A method and apparatus for a perforating gun having a movable detonator holder in a first perforating gun that is positioned inside the carrier such that the detonator is not directly positioned end to end nor side by side with the detonating cord in the loading tube. When a second perforating gun is screwed onto the first perforating gun, the entire charge tube assembly moves, closing the detonator holder further into the carrier such that the detonating holder closes in on the detonating cord until the detonator is adjacent to the detonating cord to connect the detonator to detonating cord ballistic train.

Abstract: A method and apparatus for containing one or more shaped charges in a single plane, using a shaped charge housing containing a cluster of one or more shaped charges. The cluster contains with the apex ends facing each other, arrayed about the center axis of a gun body, and detonated from a single initiator located in the middle of the cluster of the one or more shaped charges. The shaped charge housing can be one of many shaped charge housings coupled together to perforate in a plurality of single planes.

Abstract: A method and apparatus for providing a universal plug in cartridge detonator capability in box-by-box perforating guns by providing a tandem sub, having a cartridge detonator assembly, that is capable of connecting to a box end of a perforating gun on one side and connecting to a pinned end of a second perforating gun.

Abstract: A method and apparatus for coupling a pre-wired end fitting with a shaped charge loading tube where the end fitting centers and orients the loading tube within a perforating gun and further includes a selective switch, feed through contact and orifices to insert a wireless detonator and detonating cord, the loading tube being pre-wired with insulated wire.
