Abstract
Perforating assemblies and perforating safety systems capable of being disposed in a wellbore for hydrocarbon fluid production are described. The perforating assemblies can include an isolation device that is capable of preventing a detonation train when the assemblies are in a first orientation and allowing a detonation train when the perforating assemblies are in a second orientation. The isolation device can be automatically reoriented or reconfigured upon a change in the orientation of the perforating assembly.
Claims14
A perforating assembly capable of being disposed in a bore of a subterranean formation, the perforating assembly comprising:
- an isolation device that is configured to prevent a detonation train when the perforating assembly is in a first orientation and that is configured to allow the detonation train when the perforating assembly is in a second orientation,
- wherein the isolation device comprises a weighted swivel structure.
A perforating safety system for use in a subterranean well, the perforating safety system comprising:
- a perforating assembly including a perforating gun, a firing head, and an isolation device, wherein the isolation device is configured to (i) selectively prevent transfer of detonation from the firing head to the perforating gun and (ii) be positioned in a configuration to allow the transfer of the detonation,
- wherein the isolation device comprises a weighted swivel structure that is gravity dependent.
