  • U S Natural Gas Leakage Model User Guide 4

    • Howarth et al4 argue that leak rates for shale gas from well to city gate are 3.6-7.9% and 1.7-6.0% for conventional gas, but as with industry assertions, there are few actual measurements. The model allows for a total leak rate as high as 12% — but this is considered extremely unlikely to be the actual case.
