Plumes from this study attribute one fth of detected emissions to midstream and two thirds to production. In contrast, state greenhouse gas reports for reporting year 2021 indicate include 14,400 metric tons of methane emissions from midstream and 8,000 metric tons from production -two thirds midstream, predominantly due to known compression and processing emissions. Results from this study illuminate this disagreement. Data developed here indicate that maintenance and other known, short-duration, emitters are likely overrepresented in aerial detections on production facilities, while unpredictable detection of known, long-duration, emission sources at midstream facilities are likely under-represented in aerial detections.
