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)

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)
