Description
The System consist of an Absolute Pressure Firing Head connected to a Pyro-Electric Time Delay and is run with the TCP Guns.

The Absolute Pressure Firing Head is a pressure actuated firing system. It Detonates when predetermined pressure is applied to the tensile stud within the head allowing the Firing Pin to strike the TCP initiator.

The Pyro-Electric Time Delay is an Electronic Time Clock rated at 300°F. for 200 hours. It is placed between the Absolute Head and the Gun Assembly. The Tool can be Pre-set to activate at 7 , 15 or 30 Minutes 1, 2, 4 up to 8 hours time intervals. This allow the operator time to achieve needed underbalance condition prior to Perforation.
It is functioned by the output of the percussion initiator of the Absolute Firing Head. Once activated will function at the Pre-set time. The circuit close and dump the electric current to the electric detonator.

Note: This tool is beneficial in all artificial lift perforating underbalanced below a completion string.
