Global assessment of oil and gas methane ultra-emitters

T. Lauvaux et al.

Summary: Methane emissions from oil and gas production and transmission significantly contribute to climate change, with ultra-emitters being the primary source. Reducing emissions from ultra-emitters can lead to substantial economic benefits at a low cost.

Simulated Methane Emission Detection Capabilities of Continuous Monitoring Networks in an Oil and Gas Production Region

Qining Chen et al.

Summary: Simulations of atmospheric dispersion of methane emissions were conducted for oil and gas production sites in the Permian Basin. The study examined the trade-offs between sensor numbers and precision in detecting methane emissions. The results indicated that a fixed monitoring network with one continuous monitor per site can reliably detect site-level methane emissions in the range of 5-10 kg/h.

Impact of the High-Emission Event Duration and Sampling Frequency on the Uncertainty in Emission Estimates

Colette Schissel et al.

Summary: Short duration measurements of methane emissions from oil and gas operations have uncertainties due to the variability of emissions. Sampling frequency and duration of emission events affect the accuracy of annual emission estimates. This study found that routine emissions are accurately captured with semiannual sampling, but infrequent high-emission rate events increase the error of annual estimates. The temporal persistence of emission events is an important factor in measurement protocol design.

Intermittency of Large Methane Emitters in the Permian Basin

Daniel H. Cusworth et al.

Summary: The Permian Basin is the largest and fastest growing oil and gas producing region in the US, with 1100 unique methane emission sources identified through airborne surveys. Most emissions come from O&G production, and frequent high-resolution monitoring is needed to accurately pinpoint persistent leaks.
