Using stable carbon isotopes to track potential leakage of carbon dioxide: Example from an enhanced coal bed methane recovery site in West Virginia, USA
International Journal of Greenhouse Gas Control(2015)
摘要
•CO2 injected into 396m deep Upper Freeport coal seam.•Wells drilled in overlying coal seam, aquifer and soil used to monitor CO2 leakage.•Carbon isotope signature of different end members at site are distinct.•δ13C signatures of injected/produced/ soil CO2, and DIC used to monitor leakage.
