Abstract
Some implementations include a perforating gun configured for transport with an internal detonator, the perforating gun to be used in a wellbore proximate to one or more subsurface formations, the perforating gun comprising: a detonator assembly positioned proximate to a ballistic initiator end of the perforating gun, wherein the detonator assembly includes the detonator; and a detonation cord positioned proximate to a receiver end of the perforating gun, wherein the ballistic initiator end is on an opposing side of the perforating gun from the receiver end; and an isolation cask disposed at the ballistic initiator end of the perforating gun, wherein the detonator assembly is recessed within the isolation cask.
Claims18
A perforating gun configured for transport with an internal detonator, the perforating gun to be used in a wellbore proximate to one or more subsurface formations, the perforating gun comprising:
- a detonation cord;
- a detonator assembly configured for transport and including the internal detonator;
- and
- an isolation cask configured to isolate the internal detonator from the detonation cord, wherein the isolation cask is configured to shield the internal detonator from at least one of radio frequencies, electromagnetic pulses, other external signals, voltages, or currents.
A perforating gun system to be used in a wellbore proximate to one or more subsurface formations, the perforating gun system comprising:
- a first perforating gun configured for transport with an internal detonator, wherein the first perforating gun includes,
- a first detonation cord,
- a detonator assembly including the detonator, and
- an isolation cask configured to isolate the detonator from the first detonation cord, wherein the isolation cask is configured to shield the detonator from at least one of radio frequencies, electromagnetic pulses, other external signals, voltages, or currents;
- and
- a second perforating gun configured to couple with the first perforating gun, the second perforating gun including at least a second detonation cord.
A method comprising:
- configuring at least a first perforating gun for transport with a pre-installed detonator, wherein the first perforating gun includes the detonator and an isolation cask configured to surround the detonator, and wherein the isolation cask is configured to shield the detonator from at least one of radio frequencies, electromagnetic pulses, other external signals, voltages, or currents;
- and
- coupling the detonator of the first perforating gun with a detonation cord of a second perforating gun.
