Methane emissions from sources in global oil and gas supply chains are estimated as approximately 100 Tg/yr, accounting for approximately 15-20% of total global anthropogenic, biogenic and geogenic emissions . Large emission events, with estimated emission rates >100 kg/h, have been identified as a significant source of methane emissions from the oil and gas sector. For example, made aerial observations across multiple oil and gas production basins in the San Joaquin Valley, Uinta, Denver-Julesburg, Permian, and Marcellus production basins in the United States and estimated that point source emissions >10 kg/h accounted for 40% of regional methane fluxes. reported on measurements from tank battery sites in the Permian Basin and concluded that 80-90% of emissions from the tank battery sites were accounted for by sites with emissions rates >10 kg/h, and 50-65% of emissions were accounted for by sites with emissions in excess of 100 kg/hr.
