Abstract: A perforating gun assembly includes an exposed perforating gun module. The exposed perforating gun module includes a housing having a first connector end, a second connector end opposite and spaced apart from the first connector end, and a chamber extending along a central axis of the housing between the first and second connector ends. The chamber is configured for receiving a detonator and optionally, a radial booster charge coupled to the detonator. A plurality of sockets extends from an outer surface of the housing towards the chamber. Each socket is configured to receive an encapsulated shaped charge. The encapsulated shaped charges may include a protrusion having an external thread that threadingly engage a complimentary threaded portion of the sockets. The detonator may directly initiate the radial booster charge or the encapsulated shaped charges.

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.

Abstract: An apparatus and method for wirelessly perforating a wellbore casing. The apparatus includes a body, at least one explosive charge, a trigger, a depth correlation device, a detonator cord, and a detonator. The depth correlation device is programmed to send a signal to the trigger to ignite/fire the detonator, which ignites the detonator cord and explosive charges. The method utilizes the apparatus of the present invention to perforate a wellbore casing.

Abstract: According to some embodiments, devices, systems, and methods for autonomously or semi-autonomously conveying downhole oil and gas wellbore tools and performing downhole oil and gas wellbore operations are disclosed. The exemplary devices, systems, and methods may include an untethered drone that substantially disintegrates and/or dissolves into a proppant when shaped charges that the untethered drone carries are detonated. Two or more untethered drones, wellbore tools, and/or data collection devices may be connected in an untethered drone string and detonated for efficiently performing wellbore operations and reducing the amount of debris left in the wellbore after such operations.

Abstract: Various well-perforating systems and methods are disclosed incorporating a self-shunting detonator. The detonator may include an electrically-conductive detonator body. A resistor initiator inside the detonator body includes first and second leads. A grounding element inside the detonator body couples the detonator body to the first lead. An electrically-conductive clip coupled to the second lead includes an arm biased to electrical contact with an external surface of the detonator body to shunt the detonator. The arm is moveable away from the detonator body to un-shunt the detonator, such as automatically in response to insertion into a detonator housing.
