Summary of Detections To-Date
• 1st Demo Flight in December 2007• Over 1150 Leak Detections (Not including discounted
leak detections, etc. Also missing data from 09’ SW Flight)
• Over 400 leaks verified• Approximately 2,178.6 mcf/d recovered• More than 3,000 miles of pipeline flown in SE, SW and
North Districts
![Page 20: A Case Study in GIS Usage for Pipeline Leak Detection ... · PDF fileA Case Study in GIS Usage for Pipeline Leak Detection Process Improvement and Efficiency GeoGathering 2010 August](https://reader031.vdocuments.net/reader031/viewer/2022021421/5aa0a79e7f8b9a89178e5b5d/html5/thumbnails/20.jpg)

Example of Operational Cost Savings
• Sept. 2008 Flight in SE District was approx. 616 Miles• To cover the same area with ground patrol:
• 2 Crews (4 Total men)• 6 Hours / Day• Average 6 Miles / Day Total• Equals 100 days, 3200 man hours, not including 2
vehicles and fuel for these 5 months• 299 Tags (CHK, Foreign, Natural (Mine Cracks))• Flight time was 64 hours• Savings not only in time, but in recovered gas carried
over the time frame saved by not using ground patrols.

GIS Input to Cost Savings
• GIS interprets the detection findings via CH4/HC ratio and graph to eliminate false positive interpretation by field personnel
• Utilizing ESRI PLTS extension, individual maps for each detection can be generated with extreme efficiency and time savings yielding a user friendly output.
• Field maps can be distributed by Superintendents to the various crews for each area and they have a coordinate and map to help locate the detection on ground (direct location)
• Similar to Operations cost savings, the recovered gas carried over the time frame saved by not using standard ground patrols, and utilizing GIS to streamline the data analysis and dissemination to the field, has a very large ROI.

Possible Future Project Expansion
• Using gyro mounted high-def camera and external drive storage for digital record of patrols (with gps time frame stamp), hyperlinked to pipeline segments in GIS
• FLIR use in conjunction around compressors and dense facility groups like meter manifolds, multiple valve settings, etc.
• Explore possibility of using this as a method of meeting DOT line patrol requirements
