A paper published in October 2015 in Water Resources Research examined an area in New York above the [[Marcellus Shale]] formation. This shale which contains more than 30,000 wells that date as far back at the 1880s. The authors, Dr. James A. Montague and George F. Pinder, used a mathematical model to map the probability that new [[hydraulic fracturing]] would connect to a previously used oil and gas wells, create damage, and let methane seep. The probability was found to be ten percent or more.<ref>[http://onlinelibrary.wiley.com/doi/10.1002/2014WR016771/full "Potential of hydraulically induced fractures to communicate with existing wellbores,"] James A.
