Meetings

NOGEC Meeting 4/11/2024

Summary of Topics Discussed

  • 2022 EPA Oil and Gas tool updates – Regi Oommen (ERG) and Jeff Vukovich (EPA)
    • Discussion of the 2022 version of the tool that is being used for the 2022 Modeling Platform emissions
    • Tool will be released this week, and will be available to download
    • The tool uses 2022 activity data
    • EPA is asking for state feedback on updated default storage tank capture efficiencies incorporated into the tool
    • Additional Notes:
      • NOx and VOC emissions decreased by 11.2% and 8.8% compared to 2021
      • Decreases in emissions from emissions drilling and well completions mirrored changes in activity
      • Factors obtained from Subpart W reporting resulted in changes to emissions from all states

  • Additional sources in the oil and gas sector whose emissions are estimated outside of the EPA tool - Regi Oommen (ERG) and Jeff Vukovich (EPA)
    • Abandoned wells - approach developed in 2020 and updated for 2022
      • Approximately 3.9 million abandoned wells in the U.S.
      • Primary data sources for emissions estimates: Enverus (apprx. 2.8 million abandoned wells identified with location by county)
      • Historical USGS and state databases identify another apprx. 1.1 million abandoned wells
    • Blowdowns
    • Pigging emissions
    • Note that emissions from these sources will be included for evaluation in the 2022 EMP Data Retrieval Tool to help states review these emissions

  • Information & Action Items – Michael Ege (TCEQ)
    • Summary of latest content added to the Oil & Gas Emissions Information Repository, available at: http://vibe.cira.colostate.edu/ogec/home.htm
    • Request for state presentations on the impacts of the recently finalized Oil & Gas Methane Rule on state emissions and/or state work. Contact Jeff Vukovich or Michael Ege

NOGEC Meeting 3/14/2024

Summary of Topics Discussed

  • EDF’s study on Low-Producing Oil and Gas Wells – Jon Goldstein and Mark Omara (EDF)
    • Low-producing wells (less than 15 barrels of oil equivalent per day) account for 6% of the nation’s oil and gas production.
    • However, they are responsible for about half of the methane emitted from all wells sites.
    • These wells emit methane at a rate 6-12 times the national average.
    • Approximately 10% of the gas leaks directly to the atmosphere.
    • Study published in Nature Communications, and is available at: https://www.nature.com/articles/s41467-022-29709-3

  • Reviewing the 2022 point source oil and gas emissions – Jeff Vukovich (EPA)
    • Summary of the draft 2022 inventory for oil and gas point sources.
    • Comparison of the 2022 point inventory with oil and gas point sources in the 2020 NEI.
    • Discussion of plans for future year (analytic year) projections and possible approaches for oil and gas point sources.
    • Discussion of the April 2024 review period.
    • Update on oil and gas sector work for the 2022 EMP.

  • Information & Action Items – Michael Ege (TCEQ)
