House Science, Space, and Technology Committee

Detecting and Quantifying Methane Emissions from the Oil and Gas Sector

The purpose of this hearing is to assess the challenge of oil and gas sector methane leaks from a scientific, technological, and policymaking perspective. The hearing will discuss the current scientific consensus regarding the role of methane leaks as a driver of oil and gas sector methane emissions. The hearing will highlight recent advances in innovative leak detection and repair technologies, as well as the importance of deploying such technologies broadly throughout oil and gas sector operations to achieve large-scale reductions in methane emissions. Finally, the hearing will examine research gaps related to oil and gas sector methane emissions and opportunities for the Federal government to support scientific research activities pertaining to oil and gas sector methane leaks.

Hearing charter

Committee report

Committee staff conclude that oil and gas companies are failing to design, equip, and inform their Methane Leak Detection and Repair (LDAR) activities as necessary to achieve rapid and large-scale reductions in methane emissions from their operations. The sector’s approach does not reflect the latest scientific evidence on methane leaks. Oil and gas companies must change course quickly if the United States is to reach its methane reduction targets by the end of this decade. The Committee staff also learned that oil and gas companies have internal data showing that methane emission rates from the sector are likely significantly higher than official data reported to EPA would indicate. A very significant proportion of methane emissions appear to be caused by a small number of super-emitting leaks. One company experienced a single leak that may be equivalent to more than 80% of all the methane emissions it reported to EPA – according to EPA’s prescribed methodology – for all of its Permian oil and gas production activities in 2020.
