Study to look at emissions from gas drilling
Published: Thursday, Oct. 11, 2012, 4:16 p.m.
A University of Texas study could answer questions about the extent of air pollution from natural gas drilling.
Researchers are studying several shale-gas fields, including the Marcellus, to measure methane emissions for a study to be finished in 2013.
Methane is a potent greenhouse gas and extensive leaks from well sites, processors or pipelines could offset environmental gains from using cleaner-burning natural gas. Early studies varied widely in estimating the extent of such leaks, making conclusions elusive.
Chevron, Shell, and ExxonMobil — which control some gas lands in Western Pennsylvania — are among nine drilling companies participating. The Environmental Defense Fund also is participating.
