Embodiments of the present disclosure include a method for fabricating a perforating gun including forming an expendable hollow carrier (EHC) via a drawing process. The method also includes determining a wall thickness of the EHC is above a threshold. The method includes machining a coupling component to at least one end of the EHC. The method further includes installing perforating components within an interior of the EHC.

Expendable hollow carrier fabrication system and method

A system and method for stimulating hydrocarbon production from a wellbore that perforates the formation around the wellbore in strategic locations so that fractures can be formed in the formation having specific orientations. The system includes deep penetration perforators that extend past a portion of the formation adjacent the wellbore having locally high internal stresses (a stress cage); and big hole perforators that form perforations with a larger entrance diameter. The perforators form perforations in the formation that are axially consolidated along the wellbore. After perforating, the wellbore is hydraulically fractured with high pressure fluid, which creates fractures in a formation surrounding the wellbore that extend radially outward from the perforations. Creating perforations that are axially consolidated reduces the chances of forming competing fractures in the formation during fracturing.

System and method for perforating a wellbore

A perforating system having annular connectors for attachment between adjacent perforating guns and connectors. The connectors include male and female connectors with respective outer and inner contact surfaces. The connectors also include attachment for electrical detonators and/or booster charges for transferring ballistic detonations between the perforating gun and connector sub.

Electric and ballistic connection through a field joint

A cartridge assembly for use with a perforating system having a contact terminal that connects to a perforating signal line when inserted into a receptacle end of a perforating gun. A detonator may be included in an end of the cartridge assembly for initiating a detonating cord in the perforating gun. The cartridge assembly is a modular unit that replaces the manual connections made when assembling a string of perforating guns. The cartridge assembly may optionally include a controller switch for controlling current flow through the cartridge assembly.

Connection cartridge for downhole string

A shaped charge assembly for use in a perforating gun that further comprises a charge carrier, and gun housing. The charge carrier substantially encapsulates the closed portion of the shaped charge and extends from the outer periphery of the shaped charge to the inner diameter of the associated gun housing. Encapsulating the shaped charge substantially reduces the introduction of debris into the wellbore resulting from detonation of the perforating gun shaped charges. The charge carrier can include a multiplicity of shaped charges therein.

Non frangible perforating gun system

A perforating system having a perforating gun with a pressurizable gun body. The gun body can be pressurized prior to deployment in a wellbore, or while in the wellbore. Pressurizing the gun body can include adding fluid into the gun body, such as a pressurized gas, a liquid, or combustion products. A seal diaphragm can be used to transfer wellbore pressure into the gun body.

Pressure compensation for a perforating gun

A shaped charge assembly for use in a perforating gun that comprises a shaped charge holder, two or more shaped charges, slots formed to receive the shaped charges, and an impedance barrier disposed between adjacent shaped charges. The impedance barrier can comprise a gap formed in the shaped charge holder, where the impedance barrier runs across the shaped charge holder. The impedance barrier can be a void formed on the surface of the shaped charge holder, or can include shock attenuating material therein, such as wood, cork, cotton, polymeric materials, and combinations thereof, to name a few.
