This inventory is developed using fuel information on drilling and oil & natural gas production from the U.S. Energy Information Admistration (EIA), and downscaled to a gridded 4 km x 4 km inventory using well-level production data from Enverus Drillinginfo. The emissions are mapped on the standard National Emissions Inventory (NEI) domain. The emissions are created for 2015 to coincide with the Shale Oil & Natural Gas Nexus (SONGNEX) 2015 field study.
NOx emissions are estimated from fuel use using emission factors from the EPA Oil & Gas Tool and described by Gorchov-Negron et al. (2018).
CH4 emissions are inferred using tracer to tracer correlations from in-situ aircraft measurements during the Southeast Nexus (SENEX) Study 2013 and SONGNEX 2015 field studies.
Similarly, NMVOC emissions are inferred using tracer to tracer correlations from in-situ field campaigns in conjunction with basin oil/gas production ratio information from Enverus Drillinginfo.
The gridded emissions are provided as an ArcGIS Shapefile, and columns as follows:
