Advanced Leak Detection and Quantification of Methane Emissions Using sUAS

Detecting and quantifying methane emissions is gaining an increasingly vital role in mitigating for the oil gas industry through early detection repair will aide our understanding of how natural ecosystems are playing a global carbon cycle its impact on climate. Traditional methods measuring utilize chamber methods, bagging individual equipment, or require release tracer gas. Advanced leak techniques have been developed over past few years, utilizing technologies, such as optical imaging, mobile surveyors equipped with sensitive cavity ring down spectroscopy (CRDS), manned aircraft satellite approaches. More recently, sUAS-based approaches to provide, some ways, cheaper alternatives that also offer sensing advantages traditional including not being constrained roadways able access class G airspace (0–400 ft) where aviation cannot travel. This work looks at reviewing can be, are, carried out using small unmanned systems (sUAS) well provide clear comparison future practitioners. includes current limitations, capabilities, assumptions, survey details. The suggested technique LDAQ depends desired accuracy function time distance. Based complexity precision, most promising sUAS near-field Gaussian plume inversion (NGI) vertical flux plane (VFP), which comparable those found conventional state-of-the-art methods.
