Towards multi-scale measurement-informed methane inventories: reconciling bottom-up inventories with top-down measurements using continuous monitoring systems

Payne Institute Student Researcher Will Daniels, Fellow Arvind Ravikumar and Faculty Fellow Dorit Hammerling write this article that discusses how government policies and corporate strategies aimed at reducing methane emissions from the oil and gas sector increasingly rely on measurement-informed emissions inventories, as conventional bottom-up inventories poorly capture temporal variability and the heavy-tailed nature of methane emissions. This work is based on an 11-month methane measurement campaign at oil and gas production sites. They find that basin and operator-level top-down measurements show lower methane emissions during end-of-project than during baseline 9-months earlier. February 10, 2023.
