[Sidley Shale and Hydraulic Fracturing Report] University study finds no relationship between groundwater methane and oil and gas development. As reported in a previous Sidley Shale and Hydraulic Fracturing Report, a recent study of groundwater contamination in Ohio concluded that the source of elevated methane levels was natural coalbed methane seams and not hydraulic fracturing operations. The study, which was conducted by University of Cincinnati researchers, included samples from more than 100 water wells over a five-county area in eastern Ohio. A chemical analysis of the methane demonstrated that the methane in the water samples was consistent with coalbed methane deposits. Earlier, we reported that the researchers were not planning to publish the study’s results; however, a full report has since been issued.
