Also, it's worth mentioning that the Nature Conservancy used SGEIS and industry data and found a similar well development scenario to the one you present here. That report, An Assessment of the Potential Impacts of High Volume Hydraulic Fracturing (HVHF) on Forest Resources, can be found at www.nature.org/ourinitiatives/regions/northamerica/unitedstates/newyork/ny-hydrofracking-impacts-20111220pdf.nullTOM WILBERhttps://www.blogger.com/profile/16103105549852845055noreply@blogger.comtag:blogger.com,1999:blog-6949864949316311883.post-65693896491521107212012-08-15T12:35:38.747-07:002012-08-15T12:35:38.747-07:00Interestingly, estimates of how much gas the Marce...Interestingly, estimates of how much gas the Marcellus Shale might yield are seldom accompanied by estimates of how many wells would be needed to produce the predicted amount of gas. <br /><br />In his 2009 article "Marcellus 2008: Report card on the breakout year for gas production in the Appalachian Basin," published in the Aug. 2009 issue of Fort Worth Basin Oil and Gas Magazine (see reference #155 at http://www3.geosc.psu.edu/~jte2/references/references.html), Dr. Terry Engelder uses a model that assumes that 70% of the 73,333 "sections" (I believe a "section" is a square mile--i.e. 640 acres) in 117 counties would be drilled with 80-acre spacing (i.e. 8 wells per square mile). That's a lot of gas wells. <br /><br />Or, consider the figures given in the economic assessment portion of the most recent draft of the NYS DEC's SGEIS on shale gas. That document assumes that in an "average" development scenario, 21,067 gas wells would be drilled in "Region A" of NY state, which consists of Broome, Chemung, and Tioga Counties. That works out to about 13 gas wells per square mile, or about 1 gas well for every 16 residents of the area! It is not possible to drill at that density without creating profound negative effects on the landscape and the communities involved. Drilling at this density would also require a very, very large financial investment. It's little wonder that the gas industry seldom provides estimates of how many wells would be needed to fulfill their high-end extraction estimates.<br />Mary Sweeneyhttps://www.blogger.com/profile/08878546420428414773noreply@blogger.com
