Detection and Quantification of Underground Natural Gas – Leaks, Geologic Seeps and Decomposition

Session ID#: 78409

Session Description:
Underground sources of methane – natural gas leaks from underground infrastructure, geologic seeps, and buried organic material – constitute a major source of atmospheric methane.  Detection and quantification of these sources remains challenging due to the distributed nature of the sources and dispersed atmospheric presentation of the constituent gas emissions. Recent work indicates that commonly utilized methods for detection and measurement may perform less well than previously believed. In parallel, a rapidly advancing portfolio of new technologies promise to improve both detection and quantification. This session will focus on new emissions data and methods that improve understanding of underground gas migration and surface presentation, advance atmospheric and subsurface detection or quantification methods.  Results from field studies, controlled experiments, or modeling advances are welcome. We are also interested in studies that demonstrate practical applications of continuous monitoring, survey methods, or regional monitoring to mitigate gas migration risks or reduce climate impacts.
