    Abstract: A setting tool fora downhole tool includes a setting housing, a setting assembly, and an integrated igniter. The setting housing has a passage therethrough. The setting assembly is positioned in the passage, and includes a drive portion and a deployment portion. The drive portion has an elongate body with a propellant chamber. The deployment portion has an opening defining a drive cavity shaped to slidingly receive an end of the drive portion. The deployment portion includes a deployment end connectable to the downhole component. The integrated igniter is positioned in the propellant chamber, and includes an integrator housing, an internal propellant, and a switch assembly connected to the internal propellant. Upon triggering the switch, the internal propellant is ignited to release an ignition fluid under ignition pressure to move the deployment portion and the downhole component connected thereto to an activated position.

    Abstract: An initiator head may include a housing extending in an axial direction, a circuit board provided in an interior space of the housing, a line-in terminal provided on a first side of the housing in the axial direction and accessible from an exterior of the housing, and a fuse displaced from the circuit board in the axial direction. A thickness direction of the circuit board may be substantially parallel with the axial direction. The line-in terminal may be in electrical communication with the circuit board. The fuse may be in electrical communication with the circuit board. The circuit board may be configured to activate the fuse in response to a control signal received at the line-in terminal.

    Abstract: A perforating gun includes a charge tube, a switch carrier body, and a pin contact spacer. The switch carrier body houses an addressable switch, a spring tube which holds a spring, a detonation block, a removable interrupter, and a pin contact spacer supporting a pin contact assembly. The spring biases a switch contact terminal towards an outer surface of the switch carrier body, and the switch contact terminal is electrically connected to the addressable switch. The interrupter includes first and second portions, and is temporarily adhered to the switch carrier body such that the first portion covers the switch contact terminal and the second portion extends between a detonation cord and an instantaneous detonator in the detonation block. A first end of the charge tube is positioned around the switch carrier body, and a second end of the charge tube is secured to the pin contact space.

    Abstract: This disclosure provides methods and apparatus for stimulating a well by using structural reactive material while perforating a well casing and well formation in a well at the same time. A structural reactive material member may be attached to a shaped charge to form a hybrid charge. A detonation signal may be transmitted to the one or more hybrid charges to detonate a main explosive in the shaped charges to generate a jet to perforate the well casing and the well formation, break apart the structural reactive material into reactive material particles, and propel the reactive material particles into the well formation for deflagration in the well formation to stimulate the well.
