The DynaStage perforating system incorporates new addressable firing system technology and an improved mechanical design to operate more efficiently than traditional perforating systems. Field trials showed the system can achieve improvements in perforation quality and reliability while lowering completion costs. Key benefits include: (1) Increased safety by eliminating risks of inadvertent detonation and allowing simultaneous operations; (2) Improved reliability from reducing mechanical assembly errors and misruns; (3) Faster surface assembly and transitions between stages by testing components above ground. The system successfully completed over 7,500 field trials with a misrun rate of 1 per 420 runs.

The use of wireless technology in industrial automation systems offers a number of potential benefits, from the obvious cost reduction brought about by the elimination of wiring to the availability of better plant information, improved productivity and better asset management.
However, its practical implementation faces a number of challenges: not least the present lack of a universally agreed standard. This whitepaper looks at some of these challenges and presents the approach being taken by Yokogawa.

China has a rapidly developing submarine cable system manufacturing industry which operates in a healthy competitive manner. Subsea cables can fall into several different system product streams including relatively standard products for long haul telecoms projects (the subject of this paper) and customised products for the Oil & Gas, Scientific Observation Systems, Defence applications and HV subsea cables. While much of the Telecoms product has been sold in the domestic market, Hengtong Marine has broken into the International Market by addressing client concerns over quality and now has a track record for deployed overseas systems. This has been achieved in part by completing an offshore cable system sea trial, which is a requirement of the cable system qualification to ITU-T G-976 & ITU-T G.972 standards. The requirement for a sea trial is a barrier which every cable system producer has to address to achieve international sales. Hengtong Marine is moving forward to promote and improve the image of “Global Quality from China”.

The continuity of the electrical power supply is very important to consumers especially in the industrial sector. Protection relays are used in power systems to maximise continuity of supply and are found in both small and large power systems from generation, through transmission, distribution and utilisation of the power. A good understanding of their application, operation and maintenance is critical for operating and maintenance personnel.
In this workshop, you will gain a thorough understanding of the capabilities of power system protection relays and how they fit into the overall distribution network. The practical sessions covering the calculation of fault currents, selection of appropriate relays and relay coordination as well as hands-on practice in configuring and setting of some of the commonly used types of protection relays used in industry will give you an excellent understanding. Simulation software and real relays (but at safe voltages) will be used to give the participants practical experience in setting up and configuring the various power parameters. Both electro-mechanical and microprocessor relays will be used to demonstrate the key configuration settings required and the major differences in the approach adopted between these two classes of relays.
The strengths and weaknesses of the latest microprocessor (or numerical) relays as compared to the older electromechanical relays will be outlined. You will also gain a solid appreciation of how the modern relay communicates not only to the central SCADA system but also between themselves resulting in a truly multifunctional system which includes protection, control and monitoring. Finally, you will gain a solid understanding of issues of reliability and security for the modern relay.

1. TECHNOLOGY UPDATE
24 JPT • APRIL 2016
Achieving greater efficiency in perforation
systems can help lower operating costs,
particularly when completing long hori-
zontal wellbores in unconventional plays.
The DynaStage perforating system,
developed by DynaEnergetics, incorpo-
rates new technology in the addressable
firing system and an improved mechan-
ical design that eliminates potential
human error. The system can operate
more efficiently than traditional systems
and, with its additional safety features,
allow other wellsite operations to run in
parallel with the perforation process.
As a result, the system can achieve
improvements in perforation quality and
performance reliability, with fewer mis-
runs, while operating efficiently enough
to lower total completion costs. The
DynaStage system has successfully com-
pleted field trials in multiple basins and
been commercialized.
The system targets two areas to im-
prove operational efficiency and reduce
operating cost.
◗◗ Safety—the system has a simple,
intrinsically safe design that
eliminates the risk of inadvertent
detonation from stray current or
voltage. Surface explosive handling
and arming can be conducted in
less time and in parallel with other
operations. The design eliminates
the need to hold the gun system
at shallow subsurface depth
during simultaneous operations.
Both factors reduce wait times
at the wellsite.
◗◗ Reliability—the design of
the electronic system and
simplification of the mechanical
field assembly process help to
reduce the number of misruns,
which increases efficiency and
lowers the cost of completions.
Surface Assembly
Perforating operations with explosives
place the explosive components and
workers in close proximity, especially
during the arming process. Traditional
resistorized detonators can contribute to
an increased risk of injury and destruc-
tion when connecting the detonator to
the gun string and the wireline truck.
Safety procedures have been devel-
oped to address the risks in this process,
and the American Petroleum Institute
(API) provides guidelines for safe han-
dling of explosives through Recommend-
ed Practice 67 (API RP 67). One of the
established best practices is to suspend
all surface operations while working with
the resistorized detonators. The arming
and connection of a gun string at the sur-
face can take up to an hour, meaning that
no other wellsite operations can be com-
pleted during this time.
The DynaStage system removes the
risks of this process by providing an
addressable and radio frequency (RF)-
safe system with immunity to high
voltage and current levels. The firing
system is built on a low-voltage, digi-
tal communication platform that uses
the DynaEnergetics detonator technol-
ogy, proven to successfully communi-
cate and initiate on command during
more than 300,000 perforating opera-
tions, without a safety incident. This
technology enables the verification of all
components in the system, including the
addressable switch, the RF-safe detona-
tor, and the RF-safe ignitor, during all
phases of the operation.
Electrical connections and compo-
nent functions can be checked during
assembly and pumpdown operations
with a communication verifier, proving
that the gun string is fully functional,
with no mechanical or electrical con-
nection issues. Independent, third-party
testing verifies the additional protection
against voltage and current provided by
the DynaStage system (Table 1).
The safety measures built into the sys-
tem allow surface assembly to happen in
parallel with other operations. The gun
string can be fully built and tested before
connection to the wireline and without
stopping other wellsite operations. Sys-
tem features, including the plug-and-go-
style detonator and single-use connector
subs, minimize the assembly time. The

time required for changeover from a used
assembly to the connection of a new gun
system is less than 10 minutes from rig
down to rig up.
Parallel Operations
During assembly of conventional per-
forating systems, including mechanical
component assembly, arming the sys-
tem, and connecting the gun string to
the wireline, there is a risk that resistor-
ized detonators can be initiated with RF
energy,straycurrent,orstrayvoltageata
wellsite, under certain conditions.
When a traditional gun string with a
resistorized detonator is used, all sur-
face operations—including hydraulic
fracturing, radio communications, cell
phone communications, and other well-
site activities, are suspended at the start
of a perforating run until the gun string
is at least 200 ft into the well. Operations
must be halted again after perforation
when the gun is raised to within 200 ft of
the surface.
The DynaStage safe system provides a
level of safety that enables parallel oper-
ations with no depth restrictions and
without shutting down critical commu-
nications. With the protection afforded
against RF saturation, normal wellsite
operations can continue while the gun
string is lowered into and raised out of
the well. Operators using this protocol
can recover up to 30 minutes per fracture
stage in their simultaneous operations.
The overall savings during the comple-
tion can be substantial.
Reduction in Misruns
The system is intended to virtually elim-
inate misruns by aiming to achieve a
99.9% operating efficiency (1 misrun per
1,000 runs). To achieve this goal, the
mechanicalandelectricalassemblyofthe
gun system was redesigned. One major
improvement was to change the way the
detonator is assembled within the sys-
tem. A traditional detonator is assem-
bled into the perforating gun connector
sub requiring wiring connections and a
port plug with O-ring seals. Wiring con-
nection issues and leaking O-rings are
among the most common causes of per-
forating gun misruns.
With the DynaStage detonator, the
detonator wires have been removed
and replaced with an injection-molded
connector, eliminating crimped wire
connections and the associated risks of
wiring damage and poor electrical con-
nections (Fig. 1). The detonator was also
relocated to the gun body, from the tan-
dem arming sub, which allows the use of
a much shorter, disposable perforating
gun connector sub and eliminates the
port plug.
The gun is shipped to the wireline cus-
tomer fully assembled, except for the
detonator. All preshipping assembly
operations are performed in the Dyna
Energetics gun assembly line, which
has been optimized for high-volume
assembly, and automated inspection
and electrical verification of the assem-
bled product. The production line pro-
cess mitigates the risk of human error
typical in the manual redress, cleaning,
wiring, and assembly of conventional
perforating guns. Field assembly only
requires inserting the plug-and-go deto-
nator, shown in Fig. 2, and threading the
guns together.
Many additional design changes were
made to reduce the chances for human
error, assembly damage, or leakage. The
DynaStage gun system benefits are sum-
marized in the 2015 paper SPE 174922,
High-Performance Plug-and-Perf Com-
pletions in Unconventional Wells.
Field Trials, Commercialization
Field trials for the system began in Feb-
ruary 2015 and ran for 6 months. The
trials included two wireline companies
and were conducted with eight operators
in the Permian Basin and the Eagle Ford
and Marcellus shale formations. More
than 6,000 guns were fired, and more
than 1,000 stages were perforated dur-
ing the trials.
Weatherford chose to run trials of the
system based on its safety and operation-
al benefits. In addition to the intrinsi-
cally safe system that reduces the risk of
explosives handing and eliminates radio
silence concerns, the system required
less shop labor and made operations
easier at the wellsite.
Weatherford noted several advantages
ofusingthesystem.Communicationwith
the addressable detonators and igniters,
with surface and downhole verification
capabilities, enabled improved trouble-
shooting. The ease of changing from one
stage cluster of perforating guns to the
next reduced the surface transition time
for switching from a used to a newly
assembled tool string. And the ability
to continue other wellsite operations
while perforating saved equipment and
labor hours.
Cluster design changes can be made
“on the fly,” allowing operators flexibil-
ity with the number or sequence of guns,
and the guns need only to be screwed
together, with rewiring eliminated.
After the field trials, with the technol-
ogy commercialized, Weatherford began
running the DynaStage system in a high-
volume horizontal completion project
for a Permian Basin operator. The intro-
duction of the system allowed a side-by-

side comparison with a conventional gun
operation used in previous plug-and-
perforate stages. With a large data set of
more than 400 runs completed, the ben-
efits of saving time and reducing opera-
tional failures were significant.
Since the commercial launch, another
1,500 guns have been fired, bringing the
total guns fired to more than 7,500 by
the end of 2015. The production success
rate has been 1 misrun per 420 runs for a
perforating efficiency of 99.41%. Dyna
Energetics continues to refine the sys-
tem components, assembly process, and
operating procedures with the objective
of attaining the 99.9% efficiency rate.
Each perforating stage run with the
system reduced completion time by an
average of 32 minutes, compared with a
conventional system, because of the effi-
ciency of surface-level transitions from
gun to gun and well to well. Improved
downhole reliability was also achieved,
with an average decrease in nonproduc-
tive time of 2 hours per 100 runs. A sig-
nificant part of the improved reliability
was a reduced need for on-site user inter-
actions that often lead to electrical issues
andmisrunsinconventionalwiredperfo-
rating systems.
The use of the perforating system
resulted in fewer days on location and
operator cost savings (USD) as high as
six figures. The Permian Basin operator
who used the commercialized DynaStage
system has incorporated it into the com
pany’s normal completion program.
Conclusion
Through the implementation of design
and safety improvements, the DynaStage
system has demonstrated significant
improvementsinperforatingperformance
and enhanced operational efficiency,
while reducing well completion costs and
providing a safer work environment. JPT
