COMPARISON OF CO-LOCATED LASER AND METAL OXIDE CONTINUOUS MONITORING SYSTEMS

Payne Institute Research Scientist Kellis Ward, Student Researcher William Daniels, and Faculty Fellow Dorit Hammerling write about how accurate measurement of methane (CH4) concentrations on oil and gas sites is essential for accurate estimates of methane emission rates via inversion algorithms. Different types of continuous monitoring sensors are offered as commercial solutions, with varying accuracy. In this paper we compare data from co-located Metal Oxide (MOx) and Laser Spectroscopy (LS) sensors on a midstream oil and gas site, with the goal of quantifying the differences in raw concentration measurements between the two technologies.  September 12, 2024.
