A well tool () includes a perforating gun (), a sealing element (), at least one pressure sensor (), a detector (), a controller (), and an anchor (). The perforating gun () perforates the wellbore tubular in response to a firing signal. The sealing element () is connected to the perforating gun () and generates a pressure differential thereacross. The at least one pressure sensor () is associated with the sealing element () and detects a surface transmitted pressure signal. The detector () detects at least one marker () positioned along the wellbore () and which includes a perforating marker () associated with a perforating depth. The controller () is in signal communication with the at least one pressure sensor () and the detector () and is configured to transmit the firing signal to the perforating gun () only after: (i) the at least one pressure sensor () detects the surface transmitted pressure signal, and (ii) the detector () detects the perforating marker (). The anchor () is connected to the perforating gun () and selectively locks the perforating gun () to the wellbore tubular.

Perforating gun

An apparatus for detonating an explosive body associated with a downhole tool includes a plurality of firing heads, each firing head including an initiating explosive body generating a high-order input when detonated; and a funnel configured to detonate the explosive body associated with the downhole tool by using a single high-order output. The funnel has a body that includes: a plurality of input openings, each input opening positioned next to an associated initiating explosive body to receive the generated high-order input, a single output opening, and a flow path connecting the plurality of input openings with the single output opening.

Redundant firing system for wellbore tools

An interrupter for use with a wellbore tool may include a housing having an interior and a fusible body disposed in the housing interior. The fusible body may be solid below a specified temperature and liquid above the specified temperature. The fusible body communicates a first high-order detonation to a detonator only when liquid. The communicated the first high-order detonation is at a magnitude sufficient to cause the detonator to produce a second high-order detonation.
