Circulating Vented Hydraulic Firing Head
Product No. 30-11

Purpose
The BRICO Hydraulic Firing Head is designed to initiate the perforating system or other pyrotechnic tools at a predetermined value by applying tubing pressure.

The Circulating Vented Hydraulic Firing Head is to be run in on tubing or coil tubing until the system is on depth. With the vent holes being open to the annulus, the tubing fills with well bore fluid and the pressure remains balanced between the tubing and annulus allowing for well control or circulation of different fluids before firing the head. Once the conditions are correct for firing the head, a ball of the correct size and composition is pumped down the tubing making a seal on the piston. This allows the tubing to be pressured up to the calculated pressure and fire the perforating system or pyrotechnic tools below the head. The piston continues to travel and locks open the vent holes allowing for communication between the annulus and tubing again.
