Declining methane emissions and steady, high leakage rates observed over multiple years in a western US oil/gas production basin

Abstract Methane, a potent greenhouse gas, is the main component of natural gas. Previous research has identified considerable methane emissions associated with oil and gas production, but estimates of emission trends have been inconsistent, in part due to limited in-situ methane observations spanni...
