Multiscale Measurement and Modeling of Methane Emissions in US Oil and Gas Production Regions.

The emergence of the United States as the leading global producer of oil and gas has driven increased interest in the greenhouse gas emissions from US energy supply chains. Methane emissions are a major portion of these greenhouse gas emissions, and the spatial and temporal patterns of methane emissions from oil and gas sources are complex. A wide variety of measurement and modeling approaches for estimating methane emissions from US oil and gas supply chains have emerged over the last decade, and this review summarizes their current status and prospects for improvement. Although no single measurement method or modeling approach will be successful in accurately characterizing all emissions, the integration of multi-scale measurement and modeling approaches can provide accurate and comprehensive estimates of emissions.
