jpetrosky, welcome to HN.
If the wells in question are "well below drinking water aquifers," can you comment on the water contamination shown in the documentary, Gasland?
- anamax 15y agoNot so fast. From http://en.wikipedia.org/wiki/Gasland http://en.wikipedia.org/wiki/Gasland "Laboratory tests concluded that Markham’s water well contained biogenic methane, a combustible gas that occurs naturally in underground coal beds.[10] Further investigation revealed that Markham’s water well had been drilled through four different coal beds containing naturally occurring biogenic methane gas. The 2008 investigation concluded that "there [were] no indications of oil & gas related impacts to [Markham's] water well." It was also concluded that the water well of Weld County landowner Renee McClure, also featured in the film, contained naturally occurring biogenic methane not related to oil and gas activity in the area.[11] On the other hand, Dr. Anthony Ingraffea, the D. C. Baum Professor of Engineering at Cornell University, whose research has involved fracture mechanics for more than 30 years, has said that drilling and hydraulic fracturing can liberate biogenic natural gas into a fresh water aquifer. Thus, just because gas is biogenic does not necessarily indicate that it reached a well by natural means. [12] "The COGCC concluded that a well belonging to Weld County landowner Aimee Ellsworth, also featured in the film, contained thermogenic methane that was attributable to oil and gas activity in the area. The report states that Mrs. Ellsworth and an operator in the area had reached a settlement in that case.[9] Note that "oil and gas activity" doesn't imply fracking wells.
