Optimizing sensor placement to guarantee site coverage and inform analytics: how Nubo Sphere turns raw data into actionable insights, part two

Nubo Sphere measures unintended, fugitive methane emissions at oil and gas sites using a combination of purpose-built sensor technology, an informed siting procedure and advanced analytics. In part one of this series we looked at how the photoacoustic-based laser spectroscopy Nubo Sphere methane sensor provides the most accurate raw data on methane concentrations in air. In this article, we look at the Nubo Sphere siting procedure.

Nubo Sphere's performance in ADED 2023 | Version 2; the latest advancements in continuous methane emissions monitoring

Our Nubo Sphere continuous methane monitoring solution was put to the test at the Advancing Development of Emissions Detection (ADED) campaign of 2023, a blind controlled-release testing campaign organized by the Methane Technology Evaluation Center (METEC), of Colorado State University (CSU). In last year’s ADED campaign, Nubo Sphere used a common metal oxide (MOx) sensor to measure ppm concentration of methane in the air. It showed great performance compared to other technologies and solutions.

Continuous monitoring of methane emissions using Sensirion’s Nubo Sphere solution - a performance evaluation at METEC

November 2022 - Nubo Sphere is a continuous monitoring solution for methane emissions. In this test campaign in 2022 at Colorado State University’s Methane Emissions Technology Evaluation Center (METEC), a university test site simulating conditions of upstream gas wells, we evaluated its ability to detect, locate and quantify methane emissions from different equipment types under changing environmental conditions.
