A plugging assembly includes a plug and a setting tool attached directly to the plug, wherein the plug includes an elongate core with an uphole end and a downhole end opposite the uphole end, and a sealing element disposed fully around the core to seal against the casing. The plug additionally includes an anchoring system for anchoring the plug to the casing in a fixed position, a compression fitting disposed around the core at or near the uphole end of the core, and a nose at the downhole end of the core. The setting tool includes an elongate housing extending between an uphole end and a downhole end opposite the uphole end, an open passageway extending from the uphole end to the downhole end of the housing, and the downhole end of the housing is aligned to directly engage the compression fitting of the plug.

A downhole tool includes a plurality of mechanical components with some that move relative to others. The tool includes an annular charge cannister associated with the plurality of mechanical components that delivers a gas to move mechanical components. The annular charge cannister includes an annular chamber having a back wall, an interior sidewall, an exterior sidewall, and an open side opposite the back wall. The back wall and the interior sidewall and exterior sidewall form an interior space, and a power charge is disposed within the interior space of the annular chamber. An annular lid is sized and configured to mate with the open side of the annular chamber. The charge cannister may include an ignition port formed in the annular lid for receiving an igniter.

A compact setting tool that sets a packer or bridge plug in a wellbore and then self bleeds the gas pressure prior to pulling the string out of the wellbore.

A setting tool for actuating a downhole plug in a wellbore includes a housing, a piston positioned at least partially within the housing wherein the piston defines an internal firing chamber that is in fluid communication with an exhaust port, an expansion chamber positioned between an outer surface of the piston and an inner surface of the housing wherein the exhaust port is configured to convey combustion products along a combustion flowpath extending from the firing chamber and into the expansion chamber, and an exhaust diffuser distinct from the piston and the housing and including an exhaust passage and at least one baffle face, the baffle face configured to redirect the flow of combustion products along the combustion flowpath and channel the flow of combustion products into the exhaust passage.

A gas operated setting tool comprising a piston rod and an outer tool assembly having a hollow interior within which the piston rod is disposed coaxially. The outer tool assembly comprises a top cap connected to the cylinder's upper end and a bottom connector connected to the cylinder's lower end. The piston rod comprises an upper section to which a firing head attaches and a lower section to which a setting adapter attaches. The piston section's exterior surface fits within and is sealed against the cylinder's interior surface. The piston rod has a hollow power charge chamber and port holes that open into the bottom connector's upper surface. A shear ring engages a counterpart surface feature to prevents axial movement of the outer tool assembly relative to the piston rod until the power charge has fired and sheared the shear ring.

A setting tool having a tool body, a chamber configured to contain a non-explosive fuel configured to generate gas and plasma, a cavity, a bleed sub located between the chamber and the cavity. The bleed sub is configured to bleed pressure from the chamber to the cavity after the non-explosive fuel has been initiated. The setting tool also includes a piston disposed within the cavity oriented to stroke in a first direction after the non-explosive fuel has been initiated. The piston may divide the cavity into an upper volume that may receive the pressure increase from the bleed sub and a lower volume. The setting tool may also include a shaft mechanically connected to the piston within the lower volume of the cavity. The shaft may include a dampening conduit configured to drain a fluid from the lower volume after the non-explosive fuel has been initiated.

A setting tool includes a housing having an initiator compartment to receive an initiator for initiating combustion of a combustible element, a combustion compartment to receive the combustible element, and a switch compartment to at least partially receive a switch circuit for activating the initiator, a piston configured to impart a setting force against the plug in response to combustion of the combustible element, and an interrupt flowpath configured to connect at least one of the combustion compartment and the initiator compartment with the switch compartment whereby combustion products that may be created in the initiator compartment or combustion compartment would be circulated from the at least one of the combustion compartment and the initiator compartment to the switch compartment to disconnect the switch circuit in response to the activation of the initiator charge.

An actuator for setting a downhole tool comprises a first propellant configured to be ignited by an igniter, and a second propellant configured to be ignited by combustion of the first propellant, the first propellant abutting the second propellant such that the first propellant covers an axial end of the second propellant. The first propellant is configured to combust more quickly than the second propellant.

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. Exemplary embodiments for a method for setting the plug within a wellbore casing include initiating the ballistic components with the initiator and causing 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.

A power charge for actuating a wellbore tool. Combustion of the power charge generates gas and corresponding gas pressure within the wellbore tool and the power charge and wellbore tool are configured for providing a path to an expansion chamber for the gas pressure. A body of the power charge may have the shape of a regular polygonal cylinder, thus defining flow-paths for the expanding gas. The power charge may include a cylinder of energetic material and an interior space formed within the energetic material and configured for receiving an igniter and/or ignition material. Ignition of the igniter or ignition material results in combustion of the power charge.
