The Autovent Firing Head is a hydraulically activated firing head incorporating a dump sleeve that is actuated by applied pressure. Once actuated, the dump sleeve exposes four ports that can be used for production, circulation or pump volumes.

• Safe, economical, simple and reliable
• Ideal for horizontal wells and extremely deviated wells.
• Uses industry standard initiators
• Single shear device (no combinations)
• Rugged design plus large flow area makes it well suited for extreme overbalance perforating operations
• Redress Kits Available
  
  

The Magnum Autovent firing head is run in a closed environment. The work string must be filled while running the TCP bottom hole assembly into the well. Once the TCP BHA is in position combined applied & hydrostatic pressure is applied down the work string. The combined pressure then enters into the firing head through the internal pressure ports shearing the shear stud in turn hammering the firing pin onto the CP initiator initiating the explosive train. When the firing pin shifts it exposes a port that transfers the applied pressure to shear the shear screws. This applied pressure creates a differential, shifting the shifting sleeve allowing communication between the tubing and annulus through the flow ports.

WARNING: Only qualified personnel should use or assemble Magnum TCP equipment. Use of Magnum TCP equipment in contrary to our specifications may result in property damage, injury or fatality. If you are not trained in the handling and the use of explosive devices, DO NOT attempt to assemble any Magnum Perforating Systems or Magnum Firing Devices.
