CSU and subcontractor AECOM partnered with nine U.S. midstream operators to characterize emissions from natural gas gathering and boosting stations (“gathering stations”) – a sector of the natural gas supply chain where few measurements have been made and little data are available for component emissions.

Partner companies provided the study team site access to:

1. Measure methane emissions
2. Collect activity data on equipment and operations.

Field Measurements

Field measurements were made at 180 facilities in 11 U.S. states during June-November 2017. Measured facilities were sampled from 1705 partner facilities located in 28 American Association of Petroleum Geologists (AAPG) basins. Measurements were made in basins representative of current U.S. production and facilities selected for measurement shared key characteristics in proportion to all partner facilities.
