Uncertainty Quantification of Methods Used to Measure Methane Emissions of 1 g CH₄ h^-1.

ABSTRACT: The recent interest in measuring methane (CH₄) emissions from abandoned oil and gas wells has resulted in five methods being typically used. In line with the US Federal Orphaned Wells Program's (FOWP) guidelines and the American Carbon Registry's (ACR) protocols, quantification methods must be able to measure minimum emissions of 1 g of CH₄ h^-1 to within ±20%. To investigate if the methods meet the required standard, dynamic chambers, a Hi-Flow (HF) sampler, and a Gaussian plume (GP)-based approach were all used to quantify a controlled emission (Q_av; g h^-1) of 1 g of CH₄ h^-1. After triplicate experiments, the average accuracy (A_r; %) and the upper (U_u; %) and lower (U
