SURVEY REPORT
Report Name: Demo Report
Date: November 7, 2021
Contractor: Aerial Production Services
OVERVIEW
Aerial Production Services performed an Aerial Gas Leak Survey of Compressor Station and 3 Well Site Locations Outlined in the Report. The Gas Leak Survey identified 9 Total Methane Leaks. See Report Below for additional Details.
| Name | Anomaly Type | Severity(Low) | Severity(Medium) | Severity(High) |
| Compressor Station | Leak | 1 | 4 | 0 |
| Leak | 1 | 0 | 0 | |
| None | 0 | 0 | 0 | |
| Leak | 3 | 0 | 0 |
Methodology
An Aerial Flight is conducted to find locate leak areas. Larger leaks are captured with the OGI system from the UAV. Smaller leaks that the TDLAS picks up on during the flight and a good OGI video cannot be obtained are captured during the Ground Scan.

Compressor Station Crew Flight Readings
Notes: Flight path covered all visible exterior equipment. The readings above are shown from the location of the UAV at time of recording (every .80 Seconds) and are not indicative of the location of the leak. The UAV with sensor stands off from the equipment on average of 15-20 meters. See Leak information for data that corresponds to each leak.
