Characteristics and Quantification of Methane Emission from Oil and Gas Production Wells
Production wells in oil and gas production are significant sources of methane emissions,which have a substantial impact on climate change.This study utilized portable Flame Ionization Detectors(FID)and Hi-Flow meters to investigate the methane leakage emissions characteristics of production wells in a specific oil and gas field in China.The study identified component leakage rates,quantified the emission rates of key sources,performed emission accounting,and proposed control strategy recommendations.The results indicate that the methane leakage rate from equipment components and pipelines in oil and gas field production wells is 1.9%,with pressure gauges,valves,and tanks being major contributors to the leakage sources.Significant differences in emission rates were observed among different types of components,with tank methane emission rates ranging from 4.61 to 16.73 L/min and the average methane emission rate per production well ranging from 1.43 to 43.37 L/min.The cumulative annual methane emission from the sampled production well was 76 085.86 m3,with tanks being the primary emission source,contributing 82.66%to the total emissions.
