Abstract: A gas-operated, fixed-volume, downhole setting tool includes a mandrel having an upper portion and a lower portion. The mandrel has a first end on the upper portion and a second end on the lower portion. The mandrel also includes an interior combustion chamber having a first end proximate to the first end of the mandrel and having an interior upper portion. The setting tool further includes a pressure bulkhead with a pressure igniter disposed in the mandrel at the first end of the mandrel in the interior upper portion of the mandrel. The pressure igniter is sealed to at least a first threshold pressure. The pressure bulkhead and pressure igniter form a seal on the first end of the mandrel and thereby define a fixed volume for combustion gases. Other settings tools and assemblies are presented.

Abstract: Igniter assemblies for use with setting tools are disclosed. The igniter assemblies have an electronic heating element disposed adjacent to an energetic material within a setting tool. In some embodiments, the electronic heating element is a resistor or a PCB mounted resistor. Electrical connections are attached to the heating element to provide electrical current to activate the heating element. In some instances, the electrical heating element is disposed onto an insulator cap that is coupled to a pressure block attached to the setting tool, and in some instances the electronic heating element is attached to a non-explosive portion and the energetic material is disposed within an explosive portion. When the non-explosive portion and the explosive portion are assembled, the electronic heating element is adjacent to the energetic material. Other assemblies are described.

Abstract: In the context of downhole tools, bulkhead igniter assemblies having snap-on insulators are disclosed. In some embodiments the bulkhead igniter assemblies have a bulkhead with a first end formed with at least one ridge or groove, a pressure block, a setting tool, and a snap-on insulator. The snap-on insulator has an annular body having a tubular channel through a center portion. Ridges or groves on the snap-on insulator mate with ridges or grooves on the bulkhead igniter to hold the snap-on insulator in place on the bulkhead igniter by interaction of the ridge or groove of the snap-on insulator with the ridge or groove on the first end of the bulkhead igniter. Other embodiments are disclosed.

Abstract: In the context of downhole tools, fixed volume power charge initiator assemblies and bottom hole assemblies utilizing fixed volume power charge initiator assembly are disclosed. The fixed volume power charge initiator assembly has a pressure bulkhead coupled to a cartridge. The cartridge includes an igniter disposed within an interior cavity of the cartridge. When used in a bottom hole assembly the fixed volume power charge initiator assembly is located in a setting tool adjacent to a power charge located within a combustion chamber of the setting tool. The combustion chamber and the cartridge together define a fixed total combustion volume. In some instances, the fixed volume power charge initiator assembly includes a power charge detector switch. Other assemblies are discussed.
