The Circulating Vented Hydraulic Firing Head has Produced in Asmary and designed 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.
