Abstract: A ballistically actuated plug (2100) for being deployed in a wellbore casing includes a ballistic housing (2106) and an outer seal housing (2102). The ballistic housing includes a first housing portion including a chamber (2208), and a second housing portion having a noncompressible core. The outer seal housing is circumferentially disposed around the noncompressible core (2216). According to an aspect, the initiator (2206) is positioned within the chamber and a detonation extender (2222) is in ballistic communication with the initiator and is circumferentially disposed around the noncompressible core. The detonation extender is configured to, upon detonation, expand the outer seal housing (2102) from an unexpanded form to an expanded form to secure the outer seal housing within the wellbore casing.

Abstract: A ballistically-safe wellbore tool may include an explosive device (114, 404), an initiator including an initiating charge (128), and a bias member (130). A relative configuration of the explosive device and the initiator may be switchable between a first configuration, in which the initiating charge is at a ballistically safe distance from the explosive device, and a second configuration, in which the initiating charge is within a ballistically operable distance from the explosive device. The bias member is configured to bias the explosive device and the initiator to the first configuration.

Abstract: A control module for use with a plurality of wellbore tools may include a power source and a logic circuit operably coupled to the power source. The logic circuit may be operably coupled to the plurality of wellbore tools through a topmost wellbore tool of the plurality of wellbore tools. The logic circuit may be configured to, in response to an initiation condition and for each wellbore tool of the plurality of wellbore tools in a sequential order from a bottommost wellbore tool to the topmost wellbore tool, determine whether the wellbore tool is a responsive wellbore tool or a non-responsive wellbore tool. In response to a determination that the wellbore tool is a responsive wellbore tool, the logic circuit may initiate the wellbore tool. In response to a determination that the wellbore tool is a non-responsive wellbore tool, the logic circuit may skip initiation of the wellbore tool.

Abstract: A self-erecting launcher assembly includes a mobile unit, and a magazine positioned in a receptacle of the mobile unit. The magazine includes a plurality of drones. A rail unit is secured to the mobile unit and moves between a closed position and an elevated position. A platform may be secured to the rail unit and is movable in an upward direction and a downward direction along a length of the rail unit. The platform is movable when the rail unit is in its elevated position. The magazine or the plurality of drones may be positioned on the platform, such that the platform moves the magazine or the plurality of drones from the mobile unit to at least one wellhead. A manipulator arm is secured to the platform and selects a drone of the plurality of drones and delivers the selected drone into a lubricator positioned at the wellhead.

Abstract: An exposed perforating gun assembly includes a perforating gun module. The module includes a first connector end, a second connector end opposite and spaced apart from the first connector end, and a communication channel extending along a central axis of the perforating gun module between the first and second connector ends. The communication channel is configured for receiving a detonator and optionally, a bi-directional booster. A socket extends from an outer surface of the perforating gun module towards the chamber, and is configured to receive an encapsulated shaped charge. The encapsulated shaped charge may include a protrusion having an external thread that threadingly engage a complimentary threaded portion of the sockets. The threads of the socket and the shaped charge may be angled. An alignment sub may be secured to the first connector end. An eccentric blasting shield may be circumferentially secured to the exposed perforating gun module.

Abstract: Exemplary embodiments of an instantaneously expanding, ballistically actuated wellbore plug and associated systems and methods are disclosed. Exemplary embodiments of an instantaneously expanding, ballistically actuated wellbore plug include, among other things, a ballistic carrier carrying ballistic components and an initiator and housed within a hollow interior chamber of an outer carrier having an unexpanded form and an expanded form. According to an exemplary method for setting the plug within a wellbore casing, initiating the ballistic components with the initiator causes the outer carrier to instantaneously transition from the unexpanded form to the expanded form in which the outer carrier is in frictional, sealing engagement with the wellbore casing.
