<p>Some conclusions:</p>
<p>"Comparison of state inspection and well spud reports (where the “spud” date is the start date of drilling) indicates a loss of well integrity in 1.9% of the oil and gas production wells spudded between 2000 and 2012. This value agrees well with some previous estimates in the literature; however, this superficial indication comes with important caveats and is an incomplete assessment. The data suggest large differences in structural integrity issues between well types, with unconventional wells showing a sixfold higher incidence of cement and/or casing issues relative to conventional wells statewide ... Unconventional wells spudded before 2009 in the northeastern (NE) counties of the state are associated with the highest occurrence of loss of structural integrity (9.84%). ... Unconventional wells spudded in the NE region since 2009 (2,714 wells) show a similarly high rate of occurrence (9.18%)."</p> Yes, about a third of methane…tag:gomarcellusshale.com,2017-11-30:2274639:Comment:7677402017-11-30T23:45:16.405ZPaul Heckberthttps://gomarcellusshale.com/profile/PaulHeckbert
<p>Yes, about a third of methane is emitted by cows, in some countries, but check this historical graph, which shows methane levels were fluctuating around 500 ppb for a million years, and then hit 1000 in 1930, and 1500 in 1980, and are now approaching 2000 ppb. Methane from cows (raised by humans) and methane leaks from natural gas production are big contributors to global warming.

<p>Yes, about a third of methane is emitted by cows, in some countries, but check this historical graph, which shows methane levels were fluctuating around 500 ppb for a million years, and then hit 1000 in 1930, and 1500 in 1980, and are now approaching 2000 ppb. Methane from cows (raised by humans) and methane leaks from natural gas production are big contributors to global warming. And as David points out, the methane melts snow and glaciers, sea levels rise, coasts are inundated, economies are shattered, and refugee crises are sparked. Look at Syria, for example.</p>

<p>Depending on info from Tony Ingraffea on these leaks would be like putting</p>

<p>A complete joke and totally unreliable.</p>
