eFire Electronic Firing Head

eFire electronic firing heads for tubing-conveyed perforating (TCP), coiled tubing (CT), slickline, and wireline give you a safer, more efficient, and economical method for a wide range of downhole explosive operations. Fully controlled from the surface, these firing heads do not require prerecorded downhole parameters. With total control, you can arm, fire, or abort the operation at any time. This flexibility lets you perforate under less rigid conditions.

eFire-TCP tubing-conveyed perforating electronic firing head enabled by Muzic wireless telemetry 

The eFire-TCP firing head enabled by Muzic wireless telemetry combines two field-proven technologies into a single firing head—IRIS intelligent remote implementation system and Muzic telemetry. With this technology integration, perforating guns are selectively triggered across multiple zones using wireless signals instead of pressure pulse commands. The eFire-TCP electronic firing head can also be run with pressure pulse commands, if necessary.

eFire-CT coiled tubing–deployed electronic firing head 

The eFire-CT firing head provides an efficient and economical method for performing a wide range of downhole explosive operations—from perforating with through-tubing equipment or HSD high shot density perforating gun systems to setting packers or plugs and running cutter services.

eFire-SL slickline-deployed electronic firing head

The eFire-SL firing head uses a unique coded sequence of tension pulls on the slickline wire to create pressure pulses, which are translated into a special signature to communicate with the firing head. The eFire-SL firing head is fully controlled from the surface and does not require prerecorded downhole parameters. Download product sheet (0.22 MB PDF)
