Short summary
This work demonstrates a simple approach for using mass flow meters connected to rigid chambers for measuring gas emissions rates in situations the meter cannot be attached directly, such as orphan oil and gas wells. This paper shows the results of performance testing, demonstrates common sources of uncertainty, and provides suggestions for how to use the approach to generate the best quality data. The findings can be used by researchers, the petroleum industry, regulators, and carbon markets.
