Using direct measures of emissions from devices on 377 wells operated by 10 companies cooperating on the survey, Allen gathered data that reshaped the EPA’s pie chart of E&P emissions of methane. The study concluded that emissions during flowback have sharply dropped from 26% in the EPA’s Greenhouse Gas Inventory to 1%. That decline, plus larger-than-expected emissions by gas-powered pneumatic control devices, pushed its share of the natural gas emissions from the EPA estimate of 26% to 42%, making it the largest single category. | Using direct measures of emissions from devices on 377 wells operated by 10 companies cooperating on the survey, Allen gathered data that reshaped the EPA’s pie chart of E&P emissions of methane.
