PREVENTATIVE PIPELINE LEAK DETECTION
HIFI ENGINEERING
Steven Koles – President & CEO
Hifi Company Background
• Founded 2007, Calgary, Alberta, Canada
• High end electrical and software engineers, with significant energy experience
• We develop turn key distributed fiber optic sensing systems sensors, hardware & artificial intelligence / machine learning interpretation software
• We use best in class components, and are open / non-exclusive
• We develop our own in house technology, and 50+ patents
• This structure allows us to focus on key goal - high quality data
• Strategic investors – focus on pipeline safety
• Downhole systems in over 1000 wellbores
– Licence to service suppliers
• Technology and co-marketing relationship for control room software
Traditional Pipeline Sensor Coverage
The industry needs more advanced & intelligent sensors
• Point sensors (mass balance sensors, microphones)
may not have sufficient resolution and precision
• Periodic surveys (manual inspections, drones,
helicopters, smart-balls) may not be deployed at the
right time
There will always be doubt across “space and time”
unless we can achieve 100% coverage and get closer to
100% assurance
Fiber Optics as a Distributed Intelligent Sensor
CONTINUOUS - EVERY CENTIMETER is sensitive with high DYNAMIC RANGE
100% COVERAGE 24/7/365 COST EFFECTIVE
World Class Sensing For Pipelines
• Hifi ceased telecom fiber based system development due to lack of fidelity
• Hifi fundamentally redesigned sensors, interrogators, and software to be
optimized for high fidelity; with integrated operation and hassle free for customers
• Each element of the system specifically designed for sensing, not telecom
• ONE SYSTEM, ONE FIBER: integrated acoustic + temperature + strain/vibration
• Costs similar to other fiber sensing technology but with significantly higher fidelity
(multiple orders of magnitude increase in sensitivity) and effective over much
longer distances representing a responsible investment with an attractive payback
• Higher sensitivity eliminates false positives, which supports 100% alarm accuracy
and more intelligent decision making ultimately to support

Fiber Optic Deployment
EXTERNAL / ON PIPE DEPLOYMENT
• Strap fiber sensor in electrical conduit directly on the pipe
• Fiber jetted in after construction or preloaded in advance
• Applicable for new construction
• Best / cheapest for new construction (< 1% of new pipeline cost)
EXTERNAL / NEAR PIPE DEPLOYMENT
• Place fiber sensor in electrical conduit close to pipe (12”)
• Fiber jetted in after construction or preloaded in advance
• Applicable for new construction or existing pipelines
• Best / cheapest for new construction (< 1% of new pipeline cost)
• Can be used for horizontal boring / directional drilling and micro trenching
INTERNAL DEPLOYMENT
• Place protected fiber sensor (stainless steel cap tube) inside pipe
• Very similar to downhole wellbore applications
• Very cost effective for existing pipelines
• Can be retractable in high consequence areas (short KM’s)
• Testing ability to co-exist with pigging
On pipe and near pipe external deployment in multi-micro duct electrical conduit
Deployment Examples
Reactive Leak Detection Performance
Leak signature from
acoustics and strain
Leak (rupture) detection using integrated acoustics, strain (and temperature)
Why integration of acoustics, strain &
temperature are so important
Preventative Security Intrusion Detection
Preventative Geotechnical Earth Quake Monitoring
Earthquake detected with an intensity rating of 3.0 at a distance from
the epicenter of over 300KM where in the intensity rating was 5.2

Preventative Geotechnical & Slope Stability Monitoring
Other pipeline integrity management applications can be leveraged using discrete data such as strain
Pig
Detection & Tracking Earthquake
Strain - Pig Tracking During Earthquake Cumulative Strain – Slope Stability Monitoring
Other Event Identification & Processing (Train)
• The pink visualization is one
that has been tagged by the
auto classification algorithm
as having a signature that
matches the training data (in
this case, previous train
crossing examples)
• Successful Event ID is not
used to notify the pipeline
operator, but instead to
eliminate from other running
algorithm such as leak
detection
Summary Lessons Learned
• Distributed fiber optic sensing and machine learning based algorithms can be
effectively utilized for faster pipeline leak detection on a real time basis, even
for low level leaks, which allows the pipeline operator to shut down the pipeline
and contain the leak that much quicker
• The same technology can detect other events enabling operators from
preventing leaks through preventative shut downs before a potential leak
occurs; example events include earthquakes, landslides, and hill slide
sloughing, third party interference such as construction crews accidentally
digging in the wrong place
• High fidelity sensing can also be leveraged for other pipeline integrity
management related applications such as pig detection / tracking, real time /
cumulative strain, security monitoring and other event identification
