Field Deployment of a Portable Optical Spectrometer for Methane Fugitive Emissions Monitoring on Oil and Gas Well Pads
Published 2019-06-01“…We present field deployment results of a portable optical absorption spectrometer for localization and quantification of fugitive methane (CH<sub>4</sub>) emissions. Our near-infrared sensor targets the 2ν<sub>3</sub> R(4) CH<sub>4</sub> transition at 6057.1 cm<sup>−1</sup> (1651 nm) via line-scanned tunable diode-laser absorption spectroscopy (TDLAS), with Allan deviation analysis yielding a normalized 2.0 ppmv∙Hz<sup>−1/2</sup> sensitivity (4.5 × 10<sup>−6</sup> Hz<sup>−1/2</sup> noise-equivalent absorption) over 5 cm open-path length. …”
