Multi-scale methane measurements at oil and gas facilities reveal necessary frameworks for improved emissions accounting

This study pairs snapshot measurements with continuous emissions monitoring systems (CEMS) to reconcile data and account for intermittent emissions. This study highlights the importance of high spatial and temporal resolution data in improving methane emissions mitigation efforts. By conducting multiscale measurements across three U.S. natural gas basins, the research demonstrates how incorporating variations in methane emissions across both space and time can enhance emission inventories. The framework developed in this study provides a measurement-based approach that could be used as guideline for future emission estimation protocols.
