Hunting’s H-1® Perforating System Advances Safety, Stage Efficiency and Success Rates

Next Generation Perforating Gun System Eliminates Common Issues
Associated with Conventional Perforating Guns

HOUSTON–(BUSINESS WIRE)–Hunting, the international energy services company, today reported that
operators using its Titan Division’s H-1® perforating system have
performed more than 38,400 runs since introduction last year without any
safety-related incidents and with fewer personnel. The H-1 system
provides operators with an advanced select fire perforating gun system
that has no wires from gun to gun, fewer connections, no exposed
detonating cords and real-time shot verification.

“The H-1 perforating system’s safety and operational features are
performing extremely well in the field and have provided for our
customers a record of zero safety incidents, a ‘game-changing’ success
rate, and a significant increase in operational efficiency,” said Rick
Bradley, President of Hunting’s Titan Division. “After more than 8,200
stages involving 38,400-plus runs to date throughout North America, our
customers are seeing incredible reliability, but more importantly, no
safety incidents related to the equipment.”

The H-1 perforating system, introduced in 2016, addressed common causes
of misruns by eliminating the potential for pinches or nicks in the lead
wire, reducing the risk of O-ring seal-point failures, and providing
more precise operational confirmation downhole on the gun string’s
status, which reduces lost time to misruns. Eighteen pounds of loaded
weight per gun was also eliminated, and the tool string was shortened to
allow more guns to be run per stage.

One service company/operator completed over 3,300 stages totaling more
than 16,000 H-1 guns with zero failures. By comparison, a successful run
rate for conventional gun systems is one failure for every 200 stages.

The service company/operator also reported an 80% decrease in gun
loading time, 66% elimination of seal connections, and the replacement
of three wire connections with the H-1 system’s simple cartridge insert.

Another service company/operator perforated approximately 3,000 stages
without a single H-1 system-related misrun. In their review of the H-1
perforating system, several cost efficiencies were noted, including
fewer personnel on site, reduced time spent handling live explosives and
preparing perforating guns, and less time onsite during
frac/plug-and-perf operations.

According to Bradley, these cost-efficiencies were by design. “Our team
engineered a ‘next generation’ system. Electrical contact components
replaced the lead wire so there is no wire from gun to gun. More than
half of the O-rings were eliminated in the gun assembly because of our
box-by-pin design, and we used Hunting’s ControlFire® package to provide
real-time shot verification and confirmation.”

ControlFire gives customers the option to skip over a perforating gun
failure and continue firing. In contrast with conventional perforating
gun systems, when an error occurs in the firing sequence, the
perforating operations stop; the gun string is removed from the wellbore
and disassembled for troubleshooting.

The H-1 perforating system’s third-party tested initiating system
enhances safety by protecting personnel from inadvertent explosive
detonations. The H-1 perforating system is electrically unarmed until
multiple specified software commands are given from the surface after
the tool is safely below ground.

“We addressed the primary reasons for conventional gun misruns and
commercialized a system that not only mitigated common failures but also
significantly improved personnel safety and operation efficiency,” said
Bradley.
