Top-down Regional Methane Gas Field Emission Estimates | TOP Energy Training

This presentation by Zachary Barkley was delivered as part of an online TOPCORP symposium, "Hot Topics", for oil and gas inspectors broadcast through Penn State Extension on October 7, 2020. Zach is a researcher for the College of Earth and Mineral Sciences from Penn State University. He explains methane emissions, how to measure them using the Bottom-Up Approach and Top-Down Approach, and modeling methane enhancements through this data.
