Customer PortalProving a Gas Leak
eTrac was commissioned to survey a pipeline to confirm the existence of a pipeline gas leak. The team had visually observed a bubbling-like disturbance at the surface of the water. In addition to seeking confirmation of the gas leak, the team needed to accurately identify the location of the leak in order to repair it.
The processor imported the data into Qimera and confirmed a plume was observed in the data.
The plume was observed in 3 data lines.

Disproving the fixed gas leak
After the gas leak was discovered, structures were installed to fix the leak. The following images were to prove the gas leak was no longer present. The structures installed on the pipe are clearly visible as is the pipe itself. The water column is clear with no evidence of disturbance.
