In general, in one aspect, embodiments relate to a detonator assembly that includes a detonator housing that includes a detonating cord receptacle and a detonator receptacle, a detonator seated within the detonator receptacle, a detonating cord seated within the detonating cord receptacle side-by-side the detonator, and a grounding clip that extends lengthwise along a substantial portion of the detonator housing, where the grounding clip extends beyond an axial end of the detonator housing.

Detonator assembly for a perforating gun assembly

Some implementations include a modular gun system for use in a wellbore comprising one or more charge segments each including a first electrical conductor having a first set of integrated electrical contacts.

Segmented gun components with integrated contacts

A detonator housing facilitates assembly of detonator components of a perforating gun. In an example, the detonator housing comprises a housing body configured for coupling to a charge tube of a perforating gun. A detonator receptacle is formed on the housing body for receiving a detonator. A detonating cord receptacle is formed on the housing body adjacent the detonator receptacle for receiving an end portion of a detonating cord in an overlapping relationship with the detonator. A detonating cord stop is formed on the detonating cord receptacle to limit an insertion depth of the detonating cord within the detonating cord receptacle.

Detonating cord depth locating feature

In general, in one aspect, embodiments relate to an electrical contact that includes a contact plate, a support plate, and three or more bends disposed between the contact plate and the support plate to counteract a force applied to the contact plate when engaged by a contact pin, where the electrical contact is configured to convey a detonating signal through an electrical feedthrough extending through at least a bulkhead of two or more perforating guns.

Electrical contact for perforating gun assembly

In general, in one aspect, embodiments relate to a charge tube assembly that includes a charge tube, a detonator housing interlocked with the charge tube, an end alignment interlocked with the charge tube, and a detonation cord extending from the detonator housing to the charge tube.

Charge tube assembly

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.

Self-shunting detonator for well perforating gun

In general, in one aspect, embodiments relate to a perforating gun that includes a gun body, a bulkhead assembly for coupling the perforating gun to an uphole perforating gun, where the bulkhead assembly is at least partially disposed in the gun body, and where the bulkhead assembly includes a bulkhead and electrical feedthrough formed in the bulkhead, and a charge tube assembly attached to the bulkhead assembly, where the charge tube is disposed in the gun body, and where the charge tube assembly includes a charge tube, a detonator housing interlocked with the charge tube, an end alignment interlocked with the charge tube, and a detonation cord extending from the detonator housing to the charge tube.
