Given the importance of flaring and venting from both environmental and resource conservation standpoints, accurate and reliable data are necessary and should be readily available to the public. ONRR has advised me that they will begin posting flaring and venting data on their website within 2 months. This is a positive step. Currently, data from the 3 primary sources differ considerably.
Data Sources:
- US Energy Information Administration (EIA): Per EIA, their flaring and venting data are received directly from the Bureau of Safety and Environmental Enforcement (BSEE).
- Office of Natural Resources Revenue: ONRR is a sister bureau of BSEE within the Department of the Interior. Per BSEE regulations, all flared or vented gas must be reported to ONRR. As noted above, ONRR will begin regularly posting flaring and venting data within the next 2 months. This is a most welcome and positive step and may help address these inconsistency issues.
- World Bank Global Gas Flaring Reduction Partnership: “a multi-donor trust fund composed of governments, oil companies, and multilateral organizations committed to ending routine gas flaring at oil production sites across the world.”
Comments:
- The EIA (from BSEE) and ONRR flaring/venting numbers should be the same given that the ONRR data are reported in accordance with BSEE regulations, and BSEE is presumably providing ONRR data to EIA. This needs to be clarified.
- The World Bank’s gas flaring estimates are based on observations from satellites. This explains their lower numbers given that vented gas would not be detected and some flares might be missed.
- In a 1/2021 interview with World Oil, the exiting BSEE Director commented that the “industry has consistently achieved a ratio of less than 1.25% of flared, vented gas to produced gas.” However, based on EIA flaring and venting data (from BSEE per EIA) and EIA gas production data, the volume of gas flared/vented exceeded 1.25% of the gas produced from 2016-2020 and was as high as 1.8% in 2019. (See the chart below.) Even if the lower ONRR flaring/venting totals are used, those volumes exceeded 1.25% in 2019 (1.5%).
- BSEE/ONRR should make more detailed flaring/venting data available so that the differences between facilities and sectors (e.g. deepwater vs. shelf) could be assessed. Efforts should also be made to post these data in a more timely manner. At this time, 2021 data are still not available.
Reports of interest:
- Argonne report for BSEE (2017):
- p. 17 – “The 2015 BSEE/BOEM study on reducing methane emissions observed that “while natural gas production has declined, …vented and flared gas volumes as a percentage of produced natural gas are increasing” and noted that additional investigation is needed to determine why.” This is consistent with my observations and is probably due in large part to the fact that most gas production is now from oil-wells (e.g. associated gas).
- p. 24 – “Argonne estimates, in 2015, platform startups for deep-water floating structures accounted for roughly 15% of the total annual flaring volume on the OCS and an additional 20% of the annual total resulted from monthly spikes associated with compressor outage, pipeline maintenance, and well-unloading.”
- Univ. of Michigan study (2020): “Large, older facilities situated in shallow waters tended to produce episodic, disproportionally high spikes of methane emissions. These facilities, which have more than seven platforms apiece, contribute to nearly 40% of emissions, yet consist of less than 1% of total platforms.”
