Quantifying Regional Methane Emissions in the New Mexico Permian Basin through a Comprehensive Aerial Survey with Yulia Chen & Evan Sherwin
Methane is a potent greenhouse gas and the primary constituent of natural gas. Improving gas conservation practices throughout the oil and gas supply chain presents a great opportunity for methane emissions mitigation. Recently, aerial screening of methane point sources has made regional comprehensive surveys possible. In this study, we leverage a comprehensive aerial survey of the New Mexico Permian Basin, finding that a relatively small number of high-impact super-emitting events drive total emissions. Our Monte Carlo simulation, implemented in Analytica, provides rigorous statistical treatment of these highly consequential, low-frequency, often intermittent emission sources while accounting for measurement uncertainty. Accounting for these uncertainties, our estimate is significantly higher than the estimate from the official US Greenhouse Gas Inventory (GHGI). This suggests that aerial measurement campaigns can find key emissions that are missed in previous methods, flagging this small number of highly consequential sources for quick repair.

Meet the speakers:
Yuanlei (Yulia) Chen is a PhD student in Adam Brandt’s lab at Stanford studying greenhouse gas emissions from oil and gas operations. Yulia earned her Bachelor’s Degrees in Environmental Engineering and Applied Mathematics from Johns Hopkins University.

Dr. Evan Sherwin is a data-informed energy policy analyst investigating the role of hydrocarbon fuels in a rapidly decarbonizing economy. Evan is the founder and chair of the Methane Emissions Technology Alliance an international seminar series and a founding member on the Board of Directors of Climate Change AI.
