The most useful measurements in the evaluation of potential leakage will be those of CO 2, CH 4 and light alkanes in soil gas and measurements of these constituents’ exchange with the atmosphere. Light alkanes are not likely to be detectable in exchange (flux) measurements in most field locations but may be observed in soil gas of petroliferous areas.

  • The U.S. natural gas industry is leaking way more methane

    What’s Wrong with MethaneWhat Causes These LeaksInventory Tallies vs. Aircraft SurveillanceHelpful Gadgets and Sound PolicyOne way to quantify the magnitude of the methane leakage is to divide the amount of methane emitted each year by the total amount of methane pumped out of the ground each year from natural gas and oil wells. The EPA currently estimates this methane leak rate to be 1.4 percent. That is, for every cubic foot of natural gas drawn from underground reservoirs, 1.4 percent of it is lost into the atmosphere. This study synthesized the results from a five-year series of 16 studies coordinated by environmental advocacy group Environmental Defense Fund (EDF), which involved more than 140 researchers from over 40 institutions and 50 natural gas companies. The effort brought together scholars based at universities, think tanks and the industry itself to make the most accurate estimate possible of the total amount of methane emitted from all U.S. oil and gas operations. It integrated data from a multitude of recent studies with measurements made on the ground and from the air. All told, based on...
