United Electric Controls has announced the availability of
beta versions of its Vanguard WirelessHART gas detector. The new detector, which has a five-year battery life, is
designed to maximize toxic or explosive gas detection points
but eliminates the need for costly and fixed wiring. United
Electric Controls says it is offering free beta trials to gain
additional feedback on customer experience and product performance prior to the official product roll-out in early 2017.
“Our new Vanguard gas detector has received approvals
from all relevant safety agencies, and we now want to
utilize the time we have, before officially releasing the
product next year, to learn as much as we can about
how it performs in the field,” said Wil Chin, Vice
President of Marketing and Business Development,
United Electric Controls.
United Electric developed the Vanguard detector in
response to the market need for a cost-effective way to add
multiple gas measurement points. The cost of adding one
new gas measurement point, including the cost and labor of
obtaining “hot” work permits, running conduits for wires,
and burying them, can exceed $10,000 per device for land-based systems and as much as five times more for offshore
applications. Wireless technology can reduce that cost up to 90% while
also making the plant much safer.
Vanguard field-interchangeable gas sensor modules detect and
record hydrogen sulfide (H2S) or methane (CH4) gas in parts per
million (PPM) or percent of lower explosive limits (LELs) respec-
tively, along with network and battery status. WirelessHAR T 7. 2
technology carries signals to local 128 x 64 pixel digital
displays or other IEC 62591 compatible connections –
all of which integrate seamlessly with existing
supervisory control and data acquisition or
asset management systems.
The Vanguard beta program will provide
companies running operations that generate H2S
or CH4 an opportunity to try it out in various set-
tings, including the following applications:
• Wireless remote and local gas detection, such
as tank farms, oil and gas production facilities, refineries,
pipelines, abandoned wells and waste treatment plants.
• Temporary situations in which the cost of setting up a wired so-
lution is completely unfeasible, such as a maintenance turnaround,
natural disaster, security breach or plant expansion.
• Asset management initiatives, where trending of emissions over
time through the deployment of multiple wireless sensors can initiate
the necessary predictive and preventive maintenance, or pollution
control monitoring. •
Schlumberger has introduced the AvantGuard advanced flowback services, which
are designed to protect the connection of the
hydraulic fracture to the wellbore to optimize
productivity in conventional and unconventional wells.
AvantGuard services comprise flowback
design and proactive fracture protection that
complement fracturing operations. Damage to the well and the formation is actively
prevented by tailoring a predictive flowback
design strategy with a defined secure operating envelope.
Application of the flowback design during
the transition to production protects and
stabilizes hydraulic fractures to efficiently
enable all the clusters in each zone to produce
without productivity impairment.
“Optimizing the poststimulation flowback
of hydraulically fractured wells is a significant
challenge for our industry,” said Wallace
Pescarini, president, Testing Services, Sch-
lumberger. “Protecting the investment made
in a complex multistage stimulation operation
is a must in today’s cost-constrained environ-
ment, and AvantGuard services provide the
integrated flowback solution that delivers
productivity and recovery.”
Modeling is conducted in the Flowback
Advisor design model built on Mangrove
engineered stimulation design. The Avant-
Guard model is adapted to the well’s specific
geological, geochemical, and geomechanical
environment. The resulting flow is continu-
ously monitored using Vx multiphase well
testing technology to accurately capture the
rapid transient changes of produced fluids and
sand content during early flow in the life of the
well. This level of control begins during coiled
tubing millout as the dynamic fluid and solids
rate information is transmitted in real time to
the coiled tubing unit to guide managing injec-
tion, return rate and pressure, and optimize
the balance condition.
Schlumberger says that the AvantGuard
services guided active control of coiled tubing
injection parameters and the wellhead choke
has kept wells in the defined secure operating
envelope to protect fracture connectivity and
