Researcher said "that at any given time, roughly 75 percent of the methane emissions from production sites in the Barnett Shale tend to come from a set of elusive and dispersed sources," EDF reports. "Higher emissions from these sites are often a result of avoidable operating conditions such as equipment leaks and tank venting that are relatively easy to prevent with frequent monitoring and repair practices."
