Comprehensive Estimation of Basin-Wide Methane Emissions from the San Joaquin Valley and Denver Oil and Gas Basins Using a Multi-Tiered Measurement and Analysis Framework

Sonoma Technology is conducting a comprehensive assessment of annual methane emissions from the oil and gas basins of the San Joaquin Valley, California, and Denver, Colorado, using a multi-tiered measurement and analysis system. The project will use a variety of measurement tools to conduct a comprehensive multi-tiered assessment of annual methane emissions from oil and gas operations, including TROPOMI satellite data, ground-based monitoring, ground-level mobile flux measurement using the FluxSense mobile platform, and the GHGSat satellite methane super-emitter survey. This will be coupled with a bottom-up inventory analysis using the VISTA methane inventory for the two basins, as well as extensive inverse modeling with TROPOMI and ground-network data. The project will also provide a summary of the super emitter contribution to the regional oil and gas methane emissions inventories, as well as guidance on deployment strategies for different systems for comprehensive assessments of regions methane emissions.</p>

Sonoma Technology partnered with GHGSat, FluxSense, the University of California, Riverside, and the University of Colorado, Boulder, on this project.</p>
