This talk addresses scientific and technical challenges to identifying and quantifying fugitive methane emissions from the production, transmission and end use of natural gas. We will examine a Bayesian inference approach built around turbulent transport theory applied to stationary and mobile measurements of methane concentration. Additionally, an information-theoretic sensor path-planning algorithm will be demonstrated for scaling the approach from the single well to the region or enterprise. It is based on a principle of maximum expected entropy reduction in the fugitive source distribution, conditioned on wind fields, associated dispersion, and prior sensor measurements.
