6.  As a greenhouse gas, methane is twenty-two times
more potent than carbon-dioxide.
 Prolonged gas leaks cause soil to become
hydrophobic, thereby destroying vegetation/crops.
 Produced fluids may contaminate soil and
groundwater.
 Gas leaks result in the loss of a valuable resource.

9. Conducting A Leak Detection Survey:
• Identifies pipeline and casing failures
• Finds above grade leaks
• Helps assess pipeline integrity
• Meets ERCB requirements
Scope & Purpose of a Leak Survey

10. Foot Patrol
Involves walking directly over the pipeline and
sampling from the ground surface.
ATV Survey
Involves riding directly over the pipeline and
sampling near the ground surface.
Aerial Survey
Involves flying over the pipeline right-of-way and
sampling the atmosphere.
Gas Trak SuprSnifr™ Survey
Involves atmospheric sampling downwind of
pipelines using available roads and access trails.

11. Method Advantages Disadvantages
Foot Patrol Exhaustive
Permits simultaneous pipeline
locates
Fences, most terrain negotiable
Slow
Expensive
Subject to weather, ground conditions
Requires locating in absence of visual
ROW
ATV Survey Exhaustive
More efficient and cost-effective
Fences problematic
Overgrowth conditions not negotiable
Land owner issues
Requires locating in absence of visual
ROW
Aerial Survey Very quick
All season surveys
Majority of leaks not detected
Expensive
Gas Trak SuprSnifr™
Survey
Fast, efficient and cost-effective for
entire gas gathering systems
Not completely exhaustive
Requires road, access trails
Dependent on meteorological
conditions
Not effective in summer
Not a visual survey

12. In 2000, Gas Trak Ltd. developed a quick and
cost-effective method for detecting natural
gas leaks.
This proprietary method relies upon an
understanding of the topographical and
meteorological effects on natural gas
plumes. Using an extremely sensitive flame
ionization unit allows for the interception
of the plume, which is followed to the
source.
