About the case
By combining source- and site-level methane measurements within a single coordinated program, Bridger provided the operator with both clear source attribution and facility-scale emissions visibility within a narrow operational timeframe.
Metrics That Matter
59kg/hr
total average emissions measured at the site level
64kg/hr
total average emissions measured at the source level
8%
variance between site and source-based measurement approaches
Challenge:
One offshore operator sought to better understand emissions at both the source and full-site level while validating alignment between different measurement methodologies across a complex asset. The operator also needed greater confidence in quantified emissions data to support operational decision-making and reporting accuracy for OGMP 2.0 Levels 4 and Level 5.
Approach:
The operator implemented a coordinated methane measurement program using Bridger’s UAV-based GML for Offshore, providing both source-level and site-level measurements. The program was designed to evaluate consistency between methodologies while providing visibility into emissions across the entire offshore facility.
Multiple distinct emission sources were identified and quantified across the site using source-level measurements, while two separate site-level assessments were completed within approximately one hour to enable direct comparability between approaches. By aligning within a narrow timeframe, the operator established a more reliable understanding of emissions performance across the asset.

Emissions Insights
The combined use of source-level and site-level methane measurement provided the operator with a more complete view of emissions across the offshore asset. Source-level measurements enabled detailed identification and quantification of individual emission sources, while site-level assessments provided broader facility-scale visibility into overall methane performance.
The program also supported prioritization of operational response activities by providing trusted measurement data down to the equipment-level.
Key Takeaway
By combining source- and site-level methane measurements within a single coordinated program, Bridger provided the operator with both clear source attribution and facility-scale emissions visibility within a narrow operational timeframe. The results increased confidence in total quantified emissions across the offshore asset.
Projected results are based on a third-party financial model developed using operator-specific inputs and assumptions. Actual results will vary based on site conditions, regulatory requirements, and other factors. This case study does not constitute a guarantee of performance, savings, or regulatory compliance.
