The problem, as is noted in Howarth's paper, is the huge amount of guesswork behind estimates of gas emissions from this (or any other) form of natural gas drilling and the subjectivity of interpretations of the greenhouse influence of such emissions (which are nearly all methane, a potent but short - lived heat - trapping gas).

Re: # 3, a big difference between horizontal drilling to exploit coal - bed methane production (which is what I think you mean) and EGS is that in CBM, the valuable item is the gas, not the water, which comes both from surface sources, and from the natural gas / coal resource.

Most studies have shown that more than half of the methane leakage from natural gas comes from drilling sites and gas processing plants (i.e. upstream emissions), with the remainder coming from pipelines and storage systems (i.e. downstream emission).
