Case Study on Methane Migration and Changes in Aquifer Properties
Recorded: March 14, 2019, 1:00 PM - 2:00 PM
The origin of methane migration into water resources has been an area of concern in areas of shale development. Pennsylvania does not regulate private homeowner water wells on top of the naturally occurring methane. Detection of a methane leakage source can be difficult to determine. Recent Penn State research has found new tracers that can help determine impacts from recent gas migration.
Josh Woda, graduate student with Penn State Department of Geosciences, will be presenting the findings of the research for the March shale webinar. “Very little is understood about how methane migrates in the subsurface and what geochemical changes it can induce along its flow path,” Woda stated. “We studied an area containing elevated methane for over seven years to understand observations related to and the plausible causes of methane migration. Observed changes in metal concentrations and sulfate depletion at the study site might allow better prediction of what happens in the subsurface at other locations when methane is introduced, as well as revealing whether methane is natural or anthropogenic in origin.”
