ORION-02 Hydromechanical Firing Head

ORION-02 Hydromechanical Firing Head is used for initiating tubing conveyed perforating systems. The firing head allows the gun system to be detonated by releasing a drop bar into the tubing or pumping rubber ball.

NOTES: Standard Drop bar and Rubber Ball are allowed to be used to initiate the Hydromechanical FH in the wells up to 40° deviation.
Deviations from 40° to 60° require a roller assisted bar or a rubber ball.
Deviations from 60° to 180° require only rubber ball.

DESIGN FEATURES AND APPLICATION:

  • Maintains pressure integrity before and after firing;
  • Can be used during perforation at drawdown (packer and packer-less application);
  • Can be used in deviated or horizontal wells with 180° deviation.
